ACADEMY OF MUSIC, or MUSICAL ACADEMY, 
By this name, formerly in France, and fiitl in Italy, were called 
an affgmbly of {uficians, or of Dilettantes, that is to fay, thofe 
who frequented Concerts for pleafin-e oaly, to whh the French

ROYAL MUSICAL ACADEMY, Is a title which is itl 
borne by the Opera of Paris. I will not here make any mentioa 
of this celbrated eabliflunent unlefs, that among all the Aca- 
demies of that kingdom, or of the world in vestal, that may 
a[redly lay the greate claim to fame. Vide O.. 
ACCENT By this name is calll, according to the mo 
general acccptation every modulation of the voice, while fak- 
iag, during its continuance, or in fle found of the fyllables 
ß nd words of which the cliikou, rl is comlfed  which deote 
an exa& uni10n between the two variations of tle Accents and 
the two diviiions of Melocty. 
AC, That is to tXy, tlm Rhyme, and the Mufical Harmony. 
CCClltUS thys the (irammarian Sergius in Donatus, is aa

are mctlods of molulating the voice thereunto, and tlmre are 
many various kinds of /[cccnts as there are general caulks for 
fucl'modulatioas. i cotlllnotl dilkourl}, tlere are dilngfled

Pun&uarion. LaXly, The Pathetic, or ccenr of Oratory, 
which, by different variations of the voJcc, hy a tone more or 
lefs ex'ared by a nethoct of dllourfe quicker, or more 
expretles thole fcmtimenrs which agitate the teakcr, am] 
icates them to r!e audience. A xdy of thet various 
and ,f their uFs in languaze, ould be the main buel 
a muticJan; and {)enn{s of Halicarnau% look% with juRice, 
ccenr in gcner;!, as the 6mmlatiot of every branch' in mufic: 
For which respire, we alG oglt to admit as an inconrciblz 
m:xi that a g::ater or legs {le%ree o' Accent, is the ral caul 
which renders language more orle} mufical; for what relation 
could muffc be:r ro clilour:, we,e not the modulations of the 
fingcranimlration of the vcrlml Accents. From whence ir fol- 
Iows that the lcl} quantity a language has of' thch like Jccen;s, 
more the harmony thercof mu be mono'onized, lanzuilhing, 
and diluful, unlel ;r teks, in the height and force of foandss 
tho' charms hich cannot be fund in their variety. 
I regnr,.l to the  ' 
  athetm and Oratorical Accent which is tim 
mo principal obk'& of the imitative mufic of the theatre, no one 
can oppoCe the maxim which I have .ut l,fin down, that every 
.man bein fubje& to the thme paffions, ought to haw a fini}ar 
exprco .{ theml for the univcrti Acccnrofnatur% which 
draxv5 from every man inarticulate tounds is one thin, and 
cc'eat of langdag% which produces an harmony FCcuiiar to a 
ation is another. The difference of a reter or lc:k imaei'- 
nation or lbntibility wch may be dmothcl bctveen one 
pyopl and anol;e:-, ought of ittif to introduce an infinite 
.rxetyn the accented idioms of a tongue, if' I have Iiberty to 
expre/ myself thus. The German, for cxampe railcs equally 
anti roughly his voice when in a r:,g% he cries ever in the three 
tone; the ltalian wixmn a thonit;d different motions agitate 
quick and fu, c,'tfivelv trom the tme cnt, varies his voice in a 
ti:utan,.t ',i,'er,::,t i'ains. The lame foun&tion of pattion 
'o&s ,OJ tbul; buc what a variety of cxprclfion in his Accents 
*p= , ;tguagc  Moreover, 't)s to this vircty alone, when

who tll it would fluX, ine-td of eakin. 
Th;s great difficulty in following, upon true, tte rules of all 
he Accents, obliges then often the comffer to give the pfer- 
ence to one or the other according to the diffe. ent kinds of 
muffcol which he is beating. For example, the airs of dane- 
ing require ?artlcularly an Accent of rlyme antl cadence, the' 
nrore of which is in every nation determined by the language. 
The Grammatical Accent ought to be the fir conthlted in the 
ecitative, torender the pronunciation of the words more atti- 
calate, which is ufd to be 1o. through the volubility o' the 
courlb, ia the lmrmonic lbuntl; but that Accent wlxich exprees 
the patfion claims the ?rece3ence in its turn in dramatic airs; 
an,1 both are lhbordinate, particularly in fymphony, to a third 
kind of Accent, which might be dcd mufical, and'is in Gme 
t])e&s determined by the nature of that melody whic! the 
clan wilhes to appropriate to the words. 
In fine, the fir anti elder defign of every kind of mufic, 
to pleit the ear, wherefore eve,y air flmuld have an agrexabte 
note: herein lies the tit2 laxv, whick is never fuffered to  
o;ated.It is necefihry then, fir to cont!t the harmony and 
the mufical Accent in the com:ofirion of any air wbatfoever; 
then, lhould our defign boa dram'trio and imitative Oantata, we 
muPr tkek the Patherin Accent, which gives to each Fentiment its 
proper expretfion, and the rational Accent, by the a2ance of 
which, tie mufician enters with ju2ice into the idens of the 
poet; for to in'flame others with that warmth, wherewith Our- 
lblves are anhnated in f['aking to tlem, we mu make t,em com- 
prehend what is the MtZi=& of ore- ditbourl. 'Fhe Grammatical 
ccent is nccellhrv fbr the tme realbn; and this rue, though 
placed here the }a in order, ia not lel indiqenCablc than tie

. hl; Inngang% has lldom occdion to be attentive to this Accent; 
he .cannot 'ia.g his air without perceiving if he lpeaks ill or 
wcli; an:t it ;s lhffi:icnt that he know's that it is always necetL 
t;-y to t}cak v:lt. Happy is it atways, when a flol½ing and

gencies of language. '['hc Frcm:h mulicians in particular, h.ve

In regard to the txvo otlmr kind, o'f Accents, they can be re- 
.duced into a letFur number of rules and the pra&ice of them 
xequiees lefs Rud% and more genius. 'l"here cannot be found 
any kind of Sang-froid in the language of the pailions; and it 
is a well known truth, that to inlire another with keling, we 
mu feel ourfelvcs. Nothing then can, in the (earch of the 
thetie ccent ful)ply the place of that natural fire, which 
4wakens at p[eafire every tbntiment; and there is no othcr art 
in this ca necery, imt to light up in one's own foul, that 
flare% xq2clx we xvifi to convey into the hearts of others. (Vide 
Fv:.) Is the rational Accent the ol'{ie& of our concerns 
l't haq lut little to do n the acquiring of it, for this rcabn, that 
the deaf cannot be taught to hear. It mu be confeffed al(o 
.that this Accent is in a lefs dcgree tl}an the orb0rs, the refult

ACCE'TS, T!c poets often ufo th: word in the phirat to 
%nlfy the bn it%if, and ordlnarily adoln to it an epithet, as 
fx'veet, ten.let, mournful Accemts. In this ca, this word receives 
exay the fcnth of its root, from whence ari;s the derivation 
f,r it is formed from Cane?e, Cantus, whence is derlved

ACCIDENT, ACCIDENTAI, We call accident, ov acc 
dental figns, the B mollare's, the Dcfis's, or B wlrato's, which 
are mt with by accident in thc courth of an air, and which, 
confrequently not being at the key, have no relation to the mode 
or p-incipal tRetn. (Vide Diefi, B mollare, Mode, Ceff or 
Key.) We call alb acciklental or ledger lines, thol which are 
added abore or below tle ulhal horizontal five, to fix the notes 
which are beyond their limits. Vide Lm. 
ACCONiPANIST, He, who in a Concert, accompanies the 
band  ith the organ, the harpfichord , or any other accompanying 
inRrument. Vide Accovavto. 
It is abfolutel neceffarV, that a good accompaniR be  ilful 
mufician; that'he be ac(luainted with the foundatlo of har- 
mony; that he know erfe&l his tRem of muffet that he 
. P Y 
hve a tnfible ear, phant fingers, and a well founded tare. 
'Tis the buffneff of the accompan;R to fix the key for the 
voices, and to give the change of motion to the orcheRra. The 
fir of there oces requires him to have always under the fin- 
ger the note of mufic, to reRrike it when neceffary, and to raife 
or let right the 'o,ce when it weakens, or is bewildered. The 
lbcond requires him to rike the bars; and his ccompanying 
with a firm roke, equal lain out, ,nd well regulated on each 
fide, for the pux'pofe of rendering the muficians tnfible of the 
time, particularly in the beginng of airs. 
In the three folloxving articles may be found thole detai! 
which are wantinff in the prefent. 
ACCOMPANING Is the execution of a complete and 
regular harmony on an inRrment proper for rendering it 
viz. the organ, the harpfichord, the theorbo, the guittar, &c. &c. 
Ve will take here, as an example, the harpfichord, a it is th:  
only inrument continued in ulb for accompanying. 
There is given, as a' direrion, one of the part of mufic, 
hich is ortfinarly the bari. qhat baff muR be touched with 
the left-hand, and with the right the harmony expreffed by th 
tone of the bari, by the melody of the other parts, which are

rcabas: the one lies in the metlxod tff marking the cyphers on the

g:'t treat of the fbrmer. 
Tie figns which are made ufe of for the purpo:b of 
the cypicrs on the ba/, are far too nu,ncrouq. Since there are 
fi few f:mdamental concords, why are lb nlanv cyphcrs necetry 
t, ex/,.'mi them } Thct three figns are cc/ui'vocal, oblbure, in- 
th/c;cnt: for example, they very' feldom determine the nature 
of the interva!a which they expre! or what is worlD, they 
note tho: rf another nature. We fix a bar to tlte one to mark 
Ixe I)icfis's, and to others, to mark the B :nollare's. The major 
=ncl [q3erfluous intervalg, and evcn the deminificd, are often 
prcflbd in the Gme manner. When the cyphers are double, they 
arc too confud when fingl% they very i]dom expre more 
thnn the idea of one interval aione; t0 rharwe have always a 
fro'at number to unde2and and to determine. But how caa 
we remedy thel i:conrenienccs? ,lu2 it be neccfiitrv to 
creal the number of tigns to exp,'cl each part? Ilar t[e com- 
pl.aint is that there are already too many. Should we reduce

' In harm'onv there am but confonances and dimances. Con- 
ffec'ntly" thee re only confonant 'accords and cliftonant. 
. Eacl; oe of diefe a&rds is fundamentally divided by tiercc$ 
6 thirds (this is M6nf. Rameau's fyem). The eoncinnos 
{ceord is compog-d of 13ree oyes, vlz. ut mi, fol, and the dif- 
naht of four, vlz. f; fi, re, fa, laying aftde the Cupportion and

Herein then we fee three dlflVerent te'xtm'es'.Of h.armonic

number of new modulations. Secorally, the dillbnance.s whlclt 
tcceed e.'ch other ordlnarilv' in the titme tone. Thtrdly and[ 
lafily, the conIbnanc½s and dlgonances wh[c1 are intcrmixt anll 
whcre the confonahce is, according to Montl Rameau, prec½lcd 
by the t'evcnth of the dominan,"or by the lixte uluinte of 
f(ua dominant. What then remains to be done foe the œncilit- 
of the accompaniment, except to polnt out, to the a½compan'/f. 
whick it is of there textures that is predomlnaat in whatever h 
-ccompanies. Moreover, tb. ls is what Monl; Rameau, wul 
hay. e. executed by clmra&eys of his invention. 
One fign alone can eatily denote th= tone, the tonic, and 
accord. From thence is derived the knowledge of the 
and B mollitre's which mutt enter into the compofitlon oœ ac- 
cords t¾om one tonic to another. 
The fundamental œucce:ition b thirds, or by' fifth.% a w61i in 
rifing as' in deftending, gives the firt texture of harmo'i: phrais, 
entirely tempofed of contbnant accords : ' 
The-fundamental thccettipn by fit'ths or by third% in 
fcending, gives the fecond texture compo!kd of cliftonant ac-

tlon gives a detending harmony. ' ' ' '

which are ulderfood, for this purpoIh, tha/: they mv be founded

h tns h0.1d t as their. opinion, .that nothing is. heartl in the ac-

moment from the air; and their, accompaniments are aIwa}' 
direc%d on this principle, tha tke plealure and'attention eva- 
porate in a dlvifion of each.. 
$ixthly, Though the accompaniment of' the organ be the 
fame with that of the harpfichord, the tafe of it is very dif- 
ferent: as the founds of the ogan are fuRalned, the courfe of 
it ought to be more bounded and !els changeable. We fhould 
raiœe the hand entire as little as poflil)le, flide the f/ngers froin 
one flop to another without removing thoih, wtfich, in the pIade 
where they are fixœ, may be neceffary to the accord wherein*we 
are intereied. There 'is nothing fo dilhgreeable as to 'hear 
rate on the oread, that kind of dry flackenlng acconpanimert, 
'3hich we. are c;lige?J .a;0 pracqlce on'the harpœchord. In generfil 
the orffan, that'i'dument, ib fonorous and majePdc, has no 
affociaton with any 0tler, and makes but an ill effect in the 
'accompaniment if it is not, at 'the mof, to f[rengthen the 
peano's and the choirs.. 
Monf. Rameau, in !is..Err.6.rsl in Mufic, has lately etablifhed 
or at leaf advanced, a fiev. 15binciple, for the omifiion of which, 
in my Encycopledie, he cenfures me highly i.e. tha the accom- 
p/mlment is a reprefentatlon of the tbnorous body. As I exa- 
mine this princip!e 'in another w'iting, I fhall dilen/ menti- 
oning it in this article which is already tOO long. My dif- 
pute with Mont'. Rameau are the mof ufelefs circumtance. in

An ingenious and agreeable air, an air cornpored with taffe and dlf-

RPEGG[O, The methed of caufing the different founds 
an accord to be heard fucccffively and rapidly, in'cad of riking 
them all at a time. There are inruments on which there can- 
not be formed a full accord but thro' the rpegglo. Such are 
the violin, the violincello, the viol, and all there which are played 
with the bow; for the convexity of the bridge hinders the bow 
from fixlog itfelf at once on all the rings. For the formation 
then of accords on there inRrumets, we are obliged to ufe the 
Arpeggio, and as we cannot draw more founds than there ar 
rings, the rpegg[o of the violincello, or of the violin, cannot 
be cornpored of more than four founds. In the Arpeggio each 
of the fingers mu be arranged on its chord, and the Arpeggio 
mu be drawn from a tingle and forcible.roke of the bow or 
fiddle-ick, which mu begin rongly on the lare ring, and 
conclude by turning and fotening o' the leffer raduall. If

Hexacord, le& the feventh without any other name than that 
of the letter B which is proper to it, as the C to ur, and the 
D to re, &c. Moreover this B was lung in two methods, that 
is to fay in a tone below la, according to the natural order of 
the gamut, or only in a remitone of the famo 1% when they 
wifhed to unite the-tetrachords, for at that time they knew 
thing of our modes or moi-rn tones. In the firit care, the 
founding very roughly, on account of the three confecutive 
tones, it was judged that it caufed to the ear an effe timilar to 
that which angulated and hard bodies caufe to the hand, for which 
reatbn it was called B hard, or B fharp, in Italian B quadro. In 
tlm feeend car% on the contrary, it was found that the fi was 
extremely left, therefore they called it B flat. By the .fame 
analogy -it might have alfo been called B round and eWe&ualllf 
the Italians called it often B rondo. 
There are ttvo methods of making ufe of the B flat the 'one 
accidental, When in ihe courl of an air it is placed on the left. 
of a note. This note is' aimoPt always the.fenfible note in the 
major tones, and rometimes the fixtlx in the minor tones when 
tle .clew ..is not' covre&ly_ numbered. The accidental B flat 
c. hanges only the note which it touches, and there which in/ne- 
tfiatcly anfwer to it or at the molt thol wMehf in the fame 
bar or fieafure, are found on the fame deere% without any 
contrary 
D Th 
z6 B 
The other method is to employ the B fiat hi tim clefF, and in 
that cat it modifies it, it a&s in the ;X'hole courfe of the air, 
and upon all the notes placed upo n the three degree, unlefs this 
B flat be accidentally deCroved by rome dieils or B a or 
that the cleft undergoes rome hange. .. , 
The potition of"the B flat 6 the clff is by no means arbi- 
trary; herein lies the reatbn: it is intended to change the place 
of t[: remitones of the fcale; moreover, tho/ two remitones 
ought always to preferve between them pretkribed intervals, i.e. 
that of a fourth on one tlde, and of a fiftlt on the other. 
Wherefore the note mi, inferice.to its fernitoh% makes in the 
flat the fifth of fi, which is its homologue in the other remitone; 
and in the flarp, the fourth of the fame fi, and the note fi, re- 
ciproeally make ia the flat the fourth of ml, and in the flarp, 
the fifth of the fame mi. If then as in example, leaving out. 
the naturM fi, a B flat was given to mid the remitone would 
change its plac% and e found a &gree 1oweri between the re 
and he mi B flat. Moreover, in this pofition, we fee that the 
to fe'tones would no longer prellrye the prefcribed diance 
tween each other for the re, which would be the inferior 
note of tim one, would mak in the flat the fixth of fi, its ho- 
m0togne in th* other, and in the flmrp, the third of the fame fi; 
a:nd this fi would mae in the flat the tl}ird of re, and in the 
thatp, the fixth of the fame re. Wherefore the two remitones 
would Be placed too near on the one fid% and t grea a 
aliirance on the other.. 
The der of B's flat ooght not tln to begin by mi, nor by 
a'nyother note of the oOave but fi, the only one which has not

B SHARP, A charaer of mufic which is written thus, ; 
and which, being placed on the left of the note, denotes that that 
note, having been precedenfiy cleYated by a dieds, or lowered 
by a B flat, ought to be replaced in its natural and diatonic 
elevation. 
The B/h/qrp was invented by Guy d'Arezzo. This authol', 
who gve names to the fix firft notes of the oave, left none but 
the letter B to expret the natural 5: For every note had, 
that tlm% its correiondent letter; nd as the diatonic chant of 
this fi is rough, w. hen we arcend to it froin the œa lie called it 
timply B dur, or hard, B quarr by an allufion w/rich I have 
mentioned in the preceding article. 
ß The B /harp fervcd in the end to deftroy the eff'e of the 
anterior B flat, on the note which followed the B /harp, that 
that the B flat being generally placed on the d, the ]3 /harp 
which followed direly after, by deftroying this B flat, produced 
only its natural. eWe, which was to repreiEnt the note fi with- 
out alteration. In the end, it was ufed for extendon, and-in 
default of another riga, to deftroy alib the eff'eEt of the diefs 
and 'tis in this mann6r that it is employed till this time. The.' 
]3 /harp effaces equally the B fla b or the diefis which have 
pYeceded it. 
There is, however, a diffin&ion to be made. If the dieds or 
the ]3 flat were accidental, they are defttoyed withgut return. by 
the ]3 /harp, in all the notes which follow it mediarely or im- 
mediately on the fame degree, until there prethnts ittlf a neur 
B flat or a ndw dieds. Bat if the ]3 flat or the dieds are or 
.the cle.ff', .the B fiarp eft.aces them only for the note which i.t 
immediately precedes, or at the m9ff for all thot which folloxr 
in the fame meafure and on the game degree; and in every note 
changed at the cleW[ whoœe alteration we wifix to deftroy, f 
many nexv B/harp's are ncetTay. All this is very poorly under 
fcood, but. fuch i tle. cuffom.." - ' 
Some lave given anotler fenfe t6 B lharp, and granting it 
only the right 'of eft.acing. tle accidental diefis's or B at's, deny 
it that of changing any thing in the Ponte of the cleft; 'fo that 
in this fcnf, '.ot'a fa dieils'd, or a fi marked with B flat on th

The tirft cuftom has entirely prevailed; rh: latter become

BALLET, A theatrical aion which is reD-efe,ted by the 
dance directed by the muœc :. 'I'llis word is de,'ived from tlle od 
French Ballet, to dance, to ting, to amufe one's tblf. The mu- 
'tic of a ballet ought to have fiill more cadence and accen than 
that of the vocal, hecauœe it is changeel to exp-ctk a greater 
number of things; and 'tis in it alone to into!re the dancer witlx 
the warmth and expreffion that the finger may receive from the 
words; and what is ftill more, it muff fupply, in the languago 
of the foul and of the pallions, every thing that the d;mce cad,- 
not exprefs to the eyes of the fpe&ators. 
Ballet is alfo the name-that is given in France to a conlured 
kind. of opera, wherein the dance is not in the leaft better regu- 
lated than in the reft, and cautks no bettel' effect. In the great- 
eft part of there operas, the acts form Ib many different fubjeets, 
lmted together only by rome general fyftems, fol'elgn to the 
aetlon, and which the t]eetator-could never perceive, had not 
the author given him a hint in tle prologue. Thetb ballets con- 
tain other ballets, which are generally called Ftes. They are 
a collection of dances which thcceed each other without plot, 
without an union in themfelves, or with the principal action, and 
Where the beft dancers inform you of nothing but that they' 
dance well. This condu&, fo little theatrical, "ffice for a ball, 
Where ever ator fatisfies his defir% rovided that lc ainures 
ß . Y . . P . . 
hun/elf, and where the intereft which the tpe&ator takes in the 
perfonages, difpenfes with an attention to things; but fuch a 
deficiency in ftbje&s and union, flould never b fuff'ered on the 
age, not even in the reprefeltation of a ball, where the vhole 
ought to be united together by rome tEcret a&iow, vhlch awakens 
the attention, and interefts tlie fpectator. This plan in cmnpo- 
fition is not without example, evm in the French opera; and 
there may be ten a very agreeable proof of it in .the F&es 
/'enetiennes. .' 
In general every dance that defcrlbes itfelf alone, and every 
'ballet, which is orilv a ball,' fhould be banifhed entirely from the 
lyric theatre. In.fhort, the a&ion of the fcene is always tlc re- 
lreœentation of another a&ion, and what we fee therein, is but 
the image'of what ftrikes our ideas; fo that it oug!t not to be 
this, or that dancer, vho prefcnts himfell before you, but th 
chara&er itfelf which. he repretEnts. Therefore, alt-l,o' a private 
dance reprcfents nothing more tha'n itfelf, that of the theatre 
ß Jh'0uld neceiarily be tlxc-imitation of romething elfe, as well a 
'the acqor, who, in his chara&er, reprefcntu a pcrlbn in difcourfe, 
and 
B A 
.,nd the fcenes which exhibit a .dilrerent place fi'om tIat whercia 
they ttand. 
The worf kind of ballets, is that which treats of allegorical 
fabje.]:s, and wherein, in contbquence, there is but imitation on 
imitation. Tke whole art of there tbrts of dramns contiffs, in 
reprefcnting under fenfible images, a reference purely intellc&ual, 
and in maffing the tpe&ator refleCt on things quite ditekrent from 
-ho/i he t[.es, as ig inecead of drawing his attention to tim 
tkence, itwere a merit to divert it from its objeOs. There kinds 
e}' ballets, be/ides, demand fo great an ingenuity in the dialogue, 
that the mufician rambles, as it were, in an unknown country, 
bctween the points, the allufions, aml eplg'ams, whil the fl)ec- 
ator doeg not forget himtlf for an infOant. According to fuclt 
a proceeding, there will never be any thing but the fentiment 
which can introduce this on the ttage, and identify it with the 
a&ors; every thing that is only intelleCtual bears it away to the 
piece, and reitores it to itfelf. As a proof, we ti:e that thole 
perfons, who with to pl'ace the mot'c wit in the theatre, are 
very men that leapt regard the illufion... 5Vhat then can the 
mufftiaa do in thole dramas which pay no refpe& or value to 
his art ? If mufie expreffes but fentlments or images, how caa 
it render ideas purely metapbyfic, fueh as allegories, vhere the 
mind is incerrantly employed With the reference which the ob- 
jeCts which are prefented io it bear to thoti: whiclt it mutt re- 
colle& in itfelf. ß ' 
Would the comPofers but refie& on the true principles of their 
art, they would ufe greater caution in the dramas which they 
receive, as well as more truth in the expreffion of their fubje&s 
and when the words of an opera will but give rome ideas, the 
mufie will loon be taught to fpeak. 
BARCAROLLES, ø A kind of longs in the Venetian language 
which are fun bt the Gondoliers in Venice. Though the airs 
of there Barcar'olls are chiefly formed for the people, and often 
cornpored by the Gondolleri themfelves; they have tb great 
a. melody, and fo pleating an accent, that there is no muffelan 
in Italy but piques himfe, lf on knowing and tinging them. 'The 
liberty that tl'e'Gondoliers have of vifit-ng all the theatres gratis, 
gives them an opportunity of forming the ear' and tare ivithout 
any Expenee, œ that they cornpole and ting their airs, as. per- 
ns, who, though conyerrant in the niceties of mufie, will not 
vary the timpie and natural difpofition of their Barearolles. The 
words of there longs are gene-rally more than natural, llke the 
½onverfation of thof$ who 6ng'.the; but thole who aredelighted 
ith the faithful i&are of a eolle's manners, and who, betides, 
love the Vneuan diale&, are eatfly led into a fondneœs for.them, 
œedueed by th beafity of the. air, fo that many curiolos have 
very large eoll. e.&in of their'piece. We 
$o B A 
%Ve cannot in confc;ence omit remarking, to tile g,'ory of' 
Taft'o, that tile greatef part of the Gondoliers can recite by 
heart, the chief part of his JeruthIem Delivered; th.at many kno(v 
it entirely, and fpend tile nights in their boats, tinging it 
ternativet from one veffel to another, that it is afibredly a 
ammtable Barclrolle. Homer alone had the honour before 
himfell of being thus celebrated, and no other epic poem has 
fince met with any timilar renown. 
BARDS, A kind of men, very ngular, and to this time 
much refpeed among the Gauls, which were at the fame tlm½ 
rophets, poets, and tauficians. Bochard derives tile word fi-om 
arat, to ting; and Camden agrees with Fcus, that Bard fig- 
nifies a finger, in the Celtic Ianguag% B_vr. 
BARIPYCNI, Tile ancients called fly this term, fire of tile 
eight founds, or ftable chords of their fyem, or diagram,. that is 
to fay, the Hypat-Hypaton, the Hypat-Mefon, tile Met, tile 
paramefe, and the Ne4, /)iazeugmenon. (Vide P¾cr . 
T/ AC HOR D.) 
BARITONO, A kind of note betveen tenor and bars. (Vide 
Cocova,.) 
BAROQ..UE, A Baroque, or rough. mufic, is that, whole 
harmony is conlured, filled with modulations and diffonances, its 
notes hard and unnatural, the intonation dicult, and the move- 
ment conicrained. 
It appears evidently that this term mu be derived from the 
13aroco of the logicians. 
' .RRE, C ]rr4, A kind of meafure. (Vide C.) 
B.a. RS, Lines drawn perpendicularly at the end of each inca- 
lure, on the five lines of the fcale, to feparate the meafure 
which finifhes from that which begins. For which veafou, thole 
notes contained between two bars always form a complete mea-. 
fur% equal in quafitity and duration to each of the other inca- 
fures comprifed between two other bar% provided the movement 
does not change; but as there are many tbrts of meafures which 
greatly differ in their duration, the fame differences are perceived 
in the quantities contained between two bars of each of there 
kinds of meafure.s. So in the great triple which is marked by' 
this fign- and which is fcruck deliberately s the œum of the 
notes comprifed between two bars ought to make a circular 
and a half s and in the finall triple  which is 'ruck quick, the'

œo thateight times the cuaritity contained between thetwo bars 
ß of 
B A 
of this IaPc meafu,'e, compo.Ces only once the quantity contained 
between two bars of the other. 
The chief fervlce of bars is to difiingui the meafures, and 
to expres their time which is always fixed on that note which 
immediately fbllows the bar. They are altb ufed in partitions 
to dcaotc the corretondcnt meathres within each divifion. 
Sme hundred years ag, a plan was laid dovn or drawing 
bars from mcatre o maire: The muc befbrc-hand wa 
timpie. There was nothing ten thercn bu ronnds rainurns, 
and black nos, exg crotchets, and hardly ever double crotchets.

tch parts as had been (ormerly Fung wifix rapidity by the 
clans o Henry I[I. and Charles IX. 
BxkSS, That of the four parts of mufic which is below the 
re, the 1owe of all whence is derived its appellation of bars. 
(Vide PARTITIOn.) 
The bars is the mo neceffary of all the parts 'tis on that 
the whole of harmony is eablied; and 'tisa general maxim 
among muficians that when the bat is. good tlxe harmony is 
rarely contrary. 
There are a eat number of diff'erent kinds of the bafs .vlz. 
The ffundamental 3 which we all treat of in the following 
article. 
The Continued, or horough BO, fo called becaufe it 
aroughout the whole pece: its chief ufe, omitting that of 
rc&ing the harmony, is to fuain the voice, and preferve tho 
tone. It is believed, that it was one Lodovico Viana, one of 
whole treatit$s is extant, who, about the beginning of the la 
century, fir brought it into ut. 
Tl? Figured Bqfi which in lieu of a tingle note, divides its 
quannty in feveral other notes under the fame concord. ' (Vide 
'IGUED HARMONY.) 
The ot]ra[cdfi whoFe air or fid)je&, bounded to a finall 
number ofmeafures, as four or eight, begins afrefh inceffatly 
whil the tperior parts purlhe their air and harmonyx' and vary 
them b 7 different m'ethods. This bars belongs originally to th 
c upIcts of the cbacon, a kind of tune but at prelent t : no 
lcnger ufed. The con,rained bars detkending diatonically or 
cnromatically and xvith flowne fi'om the tonic, or from the 
dominant, is admirable for pathetic pieces.. Tholb frequent and 
periodical returns touch inlnfibly the foul, and .infpire it with 
a dil]*otltion of hmguor and mckmcholy. Examples may be 
3z BA 
in œcveral fccnes of the F,'cnch opera. But tho' there kinds of 
the balk hav a good effe to the ear, it is feltloin the tilme in 
rega. rd to the airs that they are adapted to, which generally con- 
tute only a fimple accdmpaniment, Betide the rough and ill 
conduPed modulations, which can be fcarcely avoided, there 
airs varied in a .thourand methods, and frill monotonic, produce 
a confufion by no means harmonious; and as they have but 
little mufic in themfelves the parts above are greatly detained 
thru' the conftralnt of the bars. 
The Sin2ing .BaJ.;, is that kind of voir3e which tings the part of 
:tile bai. There are the hal's recitative, and the ba1 in chorus 
oncordants, or bars tenor, which have their place between the 
tmor and the baFs; bali's diftingmifhcd properly by that name 
alone, to which culture has given the name of bars tenor; and 
laftly, counter bars, the mort fo of all the notes which ting the 
bars below the bat itlelf, and which we muff not confound with 
a kind of inftrt, mcnt that bears a timilar name.. 
FUNDAMENTAL BASS Is that which is formed only 
from te fundamental founds of harmony, fo that below every 
concord it gives the true fundamental tbund of that concord, 
L e. the Found from whence it is dcrlved by the laws of har- 
tootry. 5/v'herein we fee that the fundamental bars can have no 
other texture than that of a regular and fundamental fucceffion 
uSthout which, the order of the fuperlor parts would be dif- 
cordaut. To underftafid this well it muff be premifed, that 
aording to the fyftem of Monœ Rameau, which I have con- 
ormed to in this work, every concord tho' formed of fevera! 
tbunds, has but one fundamental to it, that is to ihy, that which 
has produced this concord, and which ferves as a bars to it, in 
dire& and natural order. Moreover, the bat which reigns under 
all the other parts, does not alwa s exprefs the fundamental 
Y . 
œounds of the concords; for alnongft all the tounds that form a 
concord, the cornpurer may appropriate to the bars whichever 
he thinks prefe,'able, with a view to the order of this bars, to 
the beauty of his air, and above all, to the exprefllon, as I /hall 
explain it in the future pages. In this cal, the true funda- 
mental tbund, initearl of hcing in its natural plac% which is the 
baIi, is tranti, orted ilxto tile other parts, or perhaps is not 
protied at all; ad fitch a concord is ftiled a thbverted concortL 
In its foundation, a tubverted concord differs not fi'om the 
re& accord which has produced it, for they are fill the fame 
tbunds, but the/i: tbunds. forming a different combination, all' 
thotb combin;ttlons have Been long taken for to many different 
ftmdamental concords and they have received different names 
which may be feen under the'word Concord; and which have 
cominned to diitingt, ilh them, as if the difference of names 
could produce any variatlen in their nature. 
Monf. 
 A 
Vonf. ameau has flewn in his Treatire of Harmony, an?l 
VI; d'Alembert, in his Elements of Mufic, hns given a ill 
learer evidence that many of thet pretended concords were 
only the fubvertions .of a tingle one; S%. the coucord of tte 
flxth is only- a perle& concord, whole third is tranllorted to the 
b=a - i 'conveying to it the fifth' we all have the concord of 
the fixt fourih. Herein then we te three combinations of 
concord which has but three founds; thot ivhich have four ar 
capable Of four comhiations as every foufid may be conveyed 
to the bari. But by. introducing, unde[ this, another baIi, which 
under all the combinations of the time concord, prevents us al- 
ways a fundamental found; it is evident, that the number of 
eonfonant concoMs is ?educed t6 a third, and the number of dif- 
fortant to a fourth. dd to. that; all the concords by fuppofition 
which are ill reduced t8 the fame fundamentals, nod yo'u will 
find the ony. fimpIified to a dree that one could not have 
xpe&ed, cfidering the conlured ate in which its rules were 
founded-before the time of M. Rameau. It ii Certainly, as that 
author ob'lhrves i an aoniinz thing that it has been hobble 
Ie praice of'that aft to be crtied t6 he height t6 Wl'fich it 
has arrived wigout knowing its f6undatio% and that we have 
found exa4ly every rul% without being able to difcover the prin- 
ciples fr6m Wenee it is derived. 
After having e(vn what is thd fundamental bari finder the 
accord let us'now fpeak of its dreion and of the method 
by whidh it unites the concords together. The precepts of art 
on this head may be reduced to the fix followiffg rules. 
I. The fundamental bars ould never found any o'ther notes 
than th0fe of the Gamut of tliat ton% in which we ate em- 
1oyed or of that flro' which we iraend to pals... Tiffs is the 
rff and moff indifpeble of all its rules. 
II. In the fec0nd plac% its .courfe flould be fo filbmitted to 
the laws of mfdulation that it flaould never fuffer tlie idea of 
note to be loff but in taking up that of another that is to 
the fundamental bari oold never vander or fuffer the tone 
hich is, before us i to be forgot an inffant. 
III. In the third pine% it is fukjeed to the union of con- 
eords and to the preparation of diffonance% a preparation which 
as I vill e% is only one of the cafes of urea% and which 
 - 
ontEquently is never neeeary when the union can exiff Wiflx- 
but it. (Vid Uxo, to 
IV. By the fouith rule it ougt after every cliftonante, to 
follb the progrefi which is prefcribed.to it thro' the necety 
f prefervln :, ' . 
V. By th% fifth hih is only a rummary ot the precedcnt 
the funffamental bari ought only to move in conlbnant intervals; 
as it is only in a care oF broken cadence or after a concord of 
34 B A 
the dlmnifhed œeventh, that it aœcends diatonically. Every 
other movcmcnt of the œundamental bafs is erroncous. 
VI. Finally, by the fixth, the fundamental bat or harmony, 
fhould undergo no fyncope, but fhould denote the meathre and 
time by a well cedeneed change of concords; for the purpofe 
that the diffonances, which ought to be prepared, thould be fo 
on a weak time, but particularly that all the ops fhould be 
found on a fh-ong time. This xth rule meets with a great 
number of exceptions, but the compofer flmuld frill be attentive 
to it if he wiflms to form a piece, wherein the movement may 
be well pointed and ;vhofe meathre may fall with grace. 
Wherever there rules are obferved, the harmony will be re- 
gular, and without error, which will not however prevent the 
mufic from being difpleafing. (Vide Corosz';or.) 
One word of di/kuffion on the fifth rule will not be by any 
means ufelefs. Let the fundamental bars be fhifted as we pleafe 
if it be well formed, ve fhall find therein but there two things, 
either perle& concords or confonant movements, without which 
there concords could have no union, or diffonant accords in the 
a&s of cadence; in every other care, the diffonance can neither 
be well placed, or well preferred. 
Thence it follows, that the fundamental bats can have no 
recular courfe, but by one of thet three methods. Pt. 'o af- 
ced or deft:end from a. thir. d or fixth. adly. Fro TM a fourth or 
fth. 3dty. To arcend diatonically to the method of the diffo- 
hence, which. forms .the union, or by courlery, on a perfeCt 
concord. tn regard to the diatonic defcen t, .it is a plan entirely 
abolifhed in the fundamental bars, or at the ..moPe tolerated in 
cat of two con'cutive perle& concords, fepa,'ated by a ftop 
expre or underwood therein. This rule has no other excep- 
tion; and 'tis thro' not having difcovered tile true foundation 
of certain paflhgcs, that M. Rameau has made the fundamental 
bars detkend diatonically on the concords of the fcventh, which 
c.mnot be thffcrcd in a complete harmony. (Vide 
Dsso^vcz.) 
The fundamental be/5, which is added only as a proof of har- 
mony, is cut off in the execution, and often it would form a 
very ill effect; for it is according to M. Rameau, for the judg- 
ment and not 'the ear:It would at leaf} produce a very 
uPein monotony by the frequent returns of the fame concord, 
.hich?is diluild .4nd Varied  more agreeably in a combinatlon 
by different ethods on ttie thorough bars, without reckoning 
that the diffc,'cnt revolutions of harmon. y turnifl a thoufired 
methods o dding frefh beauties'to th'e ar and a new energy 
to the cxpreitlon. (Vide Cocortn.) ' 
' If tile fundamental' bat does not tkr've for the compofition of 
good muff% if cvcn it ought to b rctrenchcd in the execution, 
B A 35 
I fhall be afkcd in what particular it is of forvice ? ! ant'wet, 
that in the firPt place it trves as a rule for fcholars to learn the 
methods of forming a regular harmony, and giving to every part 
the diatonic and elementary courfe which is prefcrlbed to them 
by this fundamental bat. It foryes, fecondly, ts I have already 
f,,id, to dilkover if an harmony already cofnpoœed be good and 
regular; for every harmony which cannot be œubmitted to a 
fundamental baœs, is regularly incorre&. It is of uœe laPtly, to 
find a thorough baœs under a given ar; although, in fa, he 
who is not able to compofe dire&ly a thorough bars, will not 
be œuperior in the eompofition of a fundamental; and much leœs 
will he know the art of transforming this fundamental bars into 
a good thorough baœs. Herein then li the principal rules that M. 
Rameau l. ays down for the difcovering the fundamental bars in 
a given ar. 
I. To be certain of the tone or mode by which the air is 
begun, and of all thole thro' which we pals. There are alfo 
rules for this difcovery of the ton% but fo long, fo vague, and 
incomplet% that the ear is formed a long time before the rules 
are learned; and the fool who would endearour o make ut½ 
of them, will only gain the habit of procedlng note by not% 
without ever knowing where he is. 
IL To try fuccetilvely on each not th principal chords oœ 
the tone, beginning by the mo analogous, and continuing to the 
moec diecant, if we lle under that neceflit¾o 
III. To be attentive if the choœen chord can time with. the 
inferior parts in what precedes, and what follows, by a good fun- 
damental fucceffion; and when that cannot be døn% to return 
to our former nlan. 
IV. Never 'to vary the note of the fundamental bars till we 
'have exhaupted all the confequent notes of the parts below 
which can enter into i'ts accord, or till œome fyncopating note in 
the air, may receive two or more notes of the bafs to prepare 
the pretrved diffonances in a regular continuance. 
¾. To ptudy well the inter-union of phrafes, the potllble fuc- 
ceilion of cadence% whether full, whether avoided and particu- 
larly the Poops which come generally every four or two mealhres 
for the purpoœe of making thm aliirays fall on perle& or on ir- 
regular cadences. 
VI. LaPely, to obferve all the foregoing rules for the ½ompo- 
tltion of the fundamental bars, Here then, are the chief oblr- 
vations to b0 made for finding one under a given air, fo ther 
are often feveral to be found; but whatever may b fatd if the 
air has accent and charaEter, there is one fundamental bars only 
which we ca, adapt to it. 
Alger having given a clear rummary of the method of co m- 
poring a fundameixtal bal there would'l'cmain alfo to fhew the

TO BEAT TIME Is to fpeclfy the variety of time, by 
motions of the hand or foot which denote it duration, and by 
which all timilar meafures are rendered exa&ly equal in their

'].'he degrees of t]owne or' of quickhers whikh are given to

i-'he land on the right and left. However the French mutle 
would be in want o' a well-marked meaœur% much more than 
the Italia% for it does not convey its cadence within ifelf;' 
its mo'ements have no natural precifion: the meafure is ex-

There reigns herein a general error, which a llttle 
will eerily abolifh. It is imagined that a hearer beats the time 
of an air which he hears only becaut he feels it forcibly; and 
'rs on the conrrary beesure it is not fuciently fenfibl% or 
he does not well enter into its fpirit that he endearour% by the 
addition of motions of the hand or foot to make amends for 
what is mnting in this particular to the ear. As little as 
piece of mutic regards its cadence, we may fee the generality of 
the French, in attending to it, make a thouCand contortions, and 
you will not perceive the lea noife or fee the mo minute 
lure that has any conne&ion with the meafure'. Is it, poffibly, 
that the Germans and Italians were lefs thnfible of the meafure 
than the French ? There are feveral of my readers who,would 
not in the lea truple in hying G; but would they nifo ad- 
vane% that the mo ingcnibus muffclans are thofe who enter 
lea into the Cpirit of the mufic. It is inconteable that they 
are thoCe who heat the leafi and when y dint of exercifh they 
have gained tle habit of always.feeling :t they do not beat at 
all: this is a proof of experrance that may be feen daily 
throughout the world. It may be Cald elf% that the fame per-. 
fons, whom Iaccufe of beating time only thro' an infufficient 
feeling, do not beat in the airs where it is not to be felt; and 
angver, that in that cate 'tis becauCe they do not feel it at all. 
The ear mu be firuck at lea with fome kind of conne&i0n

The ancients, qys Monf. Burette, beat time in many dif- 
ferent methods. The mo general confied in the motion. of 
the foot vhich was railed from the ground and Kruck it alter-

times Vide Rya:E This vas commonl the office of the

mufic-maer who was called Kopu&'oc becaute he wa titu- 
sted in the mid of the choir of muffclans, and in an elevated 
tituatlon, that he might be more eerily fhen and heard by all the 
company. Thel tired bcaters were called in Greek 
and =0&$d$0, on account of the noit of their feet 
on account of the uniformity of their geures and, if I may b= 
alloved the expreffion. of fhe monotony of the rhyme, which 
they always beat fi'deux terns. They were called in Latin 
'pedarii, podarii, pediculafii. They beat time not only wlth.tho 
foot but allb with the right hand, and conjoined all the tingera 
to rike vithin the hollow of the left, antl he who expreltd the 
harmony in this manner, was called Manudu&or. Befid this

I. x. Vhenfbevcr after a concord of the feventh, the ft, ndamental 
bat5 dcœccnds from the fifth on a perle& concord, 'tis a full 
purfc& cadence, which proceeds always frt:m a dominant tonic 
to a tonic; but if the perfe cadence be avoided I,y a diltb 
nance added to the fecond note, ve may begin a fccond cadence; 
in avoiding the iiret on that fecond note, avoid this li:cond ca 
alenee, and b%in a third on the third note; then go on in tlze 
tSme plan as far as we pleak, by alending from the fourth, or 
delkending from the fifth on all the chords of the tun% and 
this forms a thccet'fion of avoided perfeCt cadences. In this fuc 
celllon, which is without a doubt, the molt harmonious, 
parts, viz. thol which form the feventh and the fifth def'ccnd on 
the third and eighth of the following concord whereas the two 
other parts, viz. tholk which form the third and eighth, re,hain 
to compotk in their turn, the feventh and the fifth, and defcend 
immediately in an alternate direction with the txvo others. In 
this manner fuch a fucceffion promotes a defcendant harmony. 
It l'houtd never econo bnt on a dominant tonic, to fall immediately 
on the tonic by a full cadence.

mutt neceffarily fall out, that the fecond not of this cadence 
futta!,s another diffonant accord. We may in the fame manner 
continue to deftend from the third or arcend from the fixtl b by 
concords of the lventh, which makes a fecond fucceffion of a- 
voided cadences, but much lefs perle& than the preceding, for 
the fevntlb which unites with the third in the perle& cadence, 
unite

and which makes alœo two eighths tb bc undcrftood fo rhar to 
avoid them, wc mu'c either remove the diffonanee or deftroy the

Whereas the interrupted cadence can never be full, it follows 
thence that a phrat can never bc concluded by it s bur we muc

IV. When the Baœs derfends by an interval of the fifth, from 
the dominant on the toni% it is as I have f, tid, an a& of perfe& 
cadence, If, on the cont, ary the bars aœcends by a fifth from 
the tonic to the domlnan b 'tis an a& of irregular-and imperfeCt 
cadence. To difcover it, we add to the concord of the tonic  
fixth maior  whence this concord takes the uame of fixth added, 
(Xride Cbzeeotl.) This fixtl b which forms a diffonance on 
the fifth is alœo healed as a diffonance on the fundamental baœs 
and as fucl b obliged to extend itfelf by aft:ending diatonically' 
on the third of the following conc. ord. 
The imperfe& cadence forths altooft an abfolute oIpo(ition to 
t_he perfe& cadence. In the tiff[ concord of each w divide the 
o.urth, which is placed between the Fifth and tlte eighth by a 
oreononce, which forms therein a near third, and this diffonance 
ought to be reduced on the following concord; therein lies what 
there two cadences have in common with each other, but here'- 
after the contrariety which they maintain, 
In the - ' 
perle& cadence the found which xs added fixes itfelf at 
the top of the interval of the' fourth, near to the eighth form- 
ivg a thi,'d' before the fifth, and produces a diffonance minob 
which is avoided by de/kendine: whereas the fundamental bah 
afce.nds from the fou'rths ot deiends from the fifth of the domio 
nant to the tonic, to maintain a perle& paufe. In the iraperle& 
'.cadence, the found which is added is fied at the bottom of the ' 
anterrol of tl{e fourth, near to the fifth, aad forming a third 
O witlz 
4  & 
with the eightl,, it produces a m.ior diffonance, which is avoids8 
by arcending; whereas the fundamental bars defcends from the 
fourth, or arcends fi-om the fifth of the tonic to the dominant, 
to efablifh an impe.rfe& paufe.--Monf..Rameau, who firPc made 
mention of this cadence;and 'who admit many exceptions from 
it, forbids us in his TreatWe on Harmon,(, page xxT, to admit 
that wherein the added found is in the flt, œupcaining a concord 
of the feventh, and that with a very weak argument, which 
have ade mention of under the word concord, lie has taken 
this concord of the feventh as fundamental fo that we mupc.pre? 
œerve a feventh by another feventh. a diffonance by an equal 
diffonance, by a timilar movement on the fundamental bars. If 
œuch a method of treating; the diffonances could be fuffered, we 
had as well flut our ears, and throw our rules into the flames. 
But the harmony , under which thi author has placed fo ftrang 
a fundamental ba, is clearly o.(erthrown by an imperf½6t 
dec% avoided by a feventh added Upon the œe½ond note,

And thi is fo true that the thorough bars, which rlkes 
dionance, is nedeqrily obliged to arcend diatonically to pre- 
fetve it, witho 'hich the paffage could be of no avail. 
cofiffs, that in the fae work, page =7=; Monf. Rameau givei 
m timilar example with the fundamental bats; 'and fince he 
app.?vcs in form. al terms, the overthrow 'whleh refults from this 
'ha$;',fich a paag ferves only 'to difdover, in his book One 
c.di&ion mre. And as much as .this' une author in a fu- 
ture 'WOrk (Geur. Harmon, page I86) feems to recolle& th 0 
true figln of-this 'fiEae; he tbeaks of it fo obfcurely and

rep roaclx 
c A 47 
reproach which he confers on MatTon,. not to have known how 
to fee the imperfect cadence in one of his perverfions. 
This fame imperfect cadence extends itfelf alfo from the fub- 
dominant to the tonic. W'e may alib avoid it, arid give it, by' 
this method, a fucceffon of feveral notes, whole concords wiI! 
compoœe an afcendant harmony, in the which the fixth and 
eighth arcend on the third and fifth of the concord, whereas the 
the third and !ifth remain to form the eighth and prepare the 
fixth. 
No author that.I know of, before Monf. 1Zameau has fi, oken 
of this harmonic rife, himfelf has only given us a view of it 
and it is certain that we could neither pra&ife a long continu- 
ance of timilar cadences, on account of the major fixths which 
would remove the modulation, nor even fitl the whole of its har- 
mony without a precaution. ß 
_After having laid open the rules and conffitution of the differ. 
ent cadences, let Us take a mew of the reafons which Monf. 
D'Alembert gives, from Monf. 1Zameau, of their denomina- 
tions. 
The perle& cadence conrifts in a courfe of the fifth, by de- 
fcendlng; and, on the contrary the impdrfe& conrifts in a courfe 
of the fifth in arcending. liereln lies th reafon :' .When i fay 
ut fol, fol is 'already enclofed within ut, fince every found, as 
ut, Carries its twetfth ' with it, the fi, fth of which, vlz. fol, is 
the eighth; fo when we go from ut to fol 'tis the generating 
found which paffes to its produ&, in fuch a manner thougl b that 
the ear always wlfhes to rct..urn to ths firft generator; on the 
contrary,. when we fay fol ut, 'rig the produ& which returns to 
its generator, the ear is fatlsfied, and wifhes nothing more. 
Moreover m this courf% fol let, the fol makes tfelf aoan under- 
ftood' in ut; br this means the ear hears' at once'the 'generator 
and its prodUcts'whereas, in the courfe ut fol 'the 'car, whi.ch in 
the' firPc found had heard ut a'nd fol, hears nothing more in the 
fecond than fol without ut. Wherefore the ftop or cadence from 
œoi to, ut, has a greater perfection than the cadence or ftop from 
Ut 'to fol. 
I't foetus, Continues Monf. D'Alembert, that in the principles 
of Monf. Rameau; *'we mawr furthermore explain the cftc& of the 
brbkhn eadenc% and tiae fnterrupted. Let us fuppof% for thi 
purpoi, :that after it 'concord of the feventh, fol, fi, re, fa, we 
hffend dlatOnicallr,'by a 'broke n cadence to. the concord la, ut, 
ml;"fol':"'It i vitgle tha this Concord is defttoyed by the con-

dominant. Ererr tom, fys Monf. D'Alembert, can always.be 
rendered thb-dmJinant by changing its mode. I will add, tl,at 
it can even bear the c0acord of a fixth added without undergo- 
ing any change. 
In regard to the interrupted cadence, which conrifts in derrend~ 
In from one uomnant on another by the mcrval of t,m third 
in this method, fol fi re fami tbl fi, re, it œ½½ms that 
may fiiIl explain it. In el%&, tlxe lcon½l concord, mi, tb!, iJ :'% 
is overthrown by the concord of the tb-dominant fcr{ t1, re, mi; 
{or whirl: reafon the interrupted cadence is equivocal to this 
fuccet'fion, fol, ti re, fafol, .ti re, mi, where the note 
after having been uld as doralhUnt, is rendered œub-dominant by 
changing the rood% which is permltted and left to the option 
of the compofer. 
Thet explanations are ingeniou and i'hew what ufe we may 
- make of the double employ in thole puffages, which feem to have 
the leait conne&ion with it. However the in.ention of.Monœ. 
D'Alembert, is not furely that we t'hould make uœe of them in 
reality in theœe puffages for p.ra&ice, but only for the compre- 
henfion of the chanes. For mt.ance the double employ of the 
interrupted cadenceS'would prevent the diffonance fa by the 
diffonance mi xvhich is contrary to rules to the utility of rules 
and particularly to the judgmen't of the ear; for in the fenration 
of the fecond eoncord tbl ti re mi at the continuance of the 
fir tbl fi re fa the ear is more attached towards the removal 
of the re, than to admit the mi as diffonant. Beginners in ge- 
neral, flould be acquainte that the double employ may be 
admitted on a concord of the feventh in the continuance of a 
-confonant accord; but that aa loon as the concord of the feventh 
follows one timilar to itfelf the double employ can have no ado 
mifflon. It is neceirary that they know alfo that the tone ought: 
not to be changed by any othediffonant accord than the fen- 
fible; whence it follows that in the broken cadence we cannot 
fuppofe any variation of tone. 
There is another kind of cadence which the mufieians do not 
look upon as fuch, and which according to its definition is 
however a true one: 'Tia the puffage of the concord of the 
venth diminlfhed on the fentible note to the concord of the 
tonic. In this puffage, there is found no harmonic union and 
it is the fecond example of this default in what i called 
alenee. One might regard the harmonlou tranfltiona aa me- 
thods of avoiding-this tme cadence in the fame manner a we 
avoid the perle& cadence of a dominant to its tonic by a chro- 
matic tranlition, but I confine royfell le½ to the explanation of 
eftablifl½d dcnominationa.onl¾0 
CADEl,ICE, 
c A 49 
CADENCE, I, in terms of tinging, that motion oœ the 
throat which the Italan call trillo, and whicll we call warlling 
which is generally on the lair note but one of a mufical ph,'a!e, 
from whence it has, doubtlet, taken the nn,ne of Cadence. x, Ve 
tky, ' That acøcret has a fine cadence."  Such a finger 
frrikes the cadence ill." 
There are two kinds of cadences. The one,' ia the fu!l ca- 
dence, which contiffs in nor beginning the wa,-bling of the voice, 
until we have refted on the higher note: The orhe,' i 
broken cadence, and in that we begin the trill of the voice. 
withou4: any preparati0h. 
The CADENCE, Is a quality of good muœc, which gives 
to thol who execute it, or who lillen to it, a liyely feeling of 
the me'afure, fo that they remark it, and perceive it fall julfly,. 
without reflecq:ing on it as it were thro' inllin,_Ct. Tl.ais quality,- 
is particularly requifite ih t;le.airs for dancing.  Th minuet 
has an agreeable Cadence."  Tidal chacoa wants a cadehce." 
TI .cadence being, in that. fenfe a quality, is'generally preceded 
by the definite article the, whereas the 'harmonic cadence bears 
as indiviclual,' the namericat article iz. A perfec"t cadence. 
lhree cadences avoided. 
Cadence fignifies alfo the conformity of' tle dancei"s ffeps, 
ith the menfur% expreffed by .the inllrument. He goes out'of 
cademe or tune.---He keeps well the cadence or time. For this 
/'eafon, the mufic'maer denotes the mov. ement of the minuet, 
b beatin ' ß ' ' 
y  tame, at the ,begunrang of each menlure; whereas 
te dancing mailer beats time only every two menlures; bccauf½ 
œo much is requitlte to form.the four teps of the minuet.

&nee is moll fenfible wherein the rhime and harmony

the choice. of concords[ i$ by no means indifferent to denote the

to di.vde thmeafures into equal powers to make their equal 
returns be felt finqe the rhime does not depend lefa from the 
accent .which is given to the melody, than from the powers. 
which are given to th* note's,' for we may have times very'

HoKIS:TER, There vho lug. in the choir of C.dtholi½' 
churches are. catted chorifter. We do not ty finger in 
church, or ½horiffcr in a concert. 
Among the reformed they call ehoriffer, him who gves th 
tone and furrains the ar of the pfalnia in their temple: He is 
feared below the. minifi:er's choir forwards; his office requires 
very itrong. vole% capable '9f exseeding that ,of the congregtion

temple. Though thee be neither profody nor meafure in the

that every one may eafity .follow l't, yet it feems to me that 
muff b..neceffary for the chorifter to mark  kind of meafure. 
'i'he rea(o of. it-is, that the chorifter being xtery dirtant fro 
feveral parts.of.the cliurch, and:,the found pfling fiowly thro 
the greater itervals,.his Voice can hardly be heard at the. 
tremities. till it .has tdkn another tone, and began a differ:nt 
note, which bcomes fo much the more fenfible in certain places t 
as the found pafiing frill nore fiowly from one extremity ta

notliing to do but to place the chorier, or )me one who dit;

' CHKOMATIC A hind of mufie Wkich proceeds in feveral 
eonfecutive femi-tone. This word is derived from th Greek 
Zp, which fignie color either becaufe tke Greeks marked 
thetk notes wkh red charaers or differently coloured; 'or 
cording to authors bocaufo the chromatic kind is a medium 
tween the two other, a colour is between black and wliite; or' 
according to hers becaufe this kind varies and embellies the 
diatonic by its fetal-tones. which- i c produces the rayne 
_ . , n mu,c, 
effe& as the 1oura in painting. 
. Boetius attributes the invention o this chromatic mufic to 
Thnotheus of Milet  but Athen2us to Epigonus. 
Arioxenes divides this kind into trce I6rts, which he call 
molle, hemiolion, and tonicurn; the conne&ions of which w6 
may here find, the tetrachord being fuppofed to be divMed in 6o

At preœent the chromatic kind conrifts in giviig fueh a'conrfe 
to the fundamental bars, that the parts of the harmony; or  at 
leaft tbmc one of them, may pr4eed by fetal-tones, as much in 
albending as defcending, Which i rho'f frequently. fot,r/d 'in the 
minor mede, ou 'account of' the-alterations to which the 6th and 
7th notes are ile&, by the very nature of the mode. 
The thccefllve fetal-tones p'a&ifed'in the chromatic, are n6t 
all of the thm kind, but almofk' alternately minors and majors 
that is to thy,' chromatics arm .aliatonics 
minor tone contains a fernitone minor or chromatic, and a fetal., 
tone major o,- diatonic, a rnafure which 'its government makes 
co,nmou to:all 'the'tones;' forhat We cannot proceed by two con 
joint and t%cccfllve femi-tones'minor; without entering on the 
harmonic; but two major tkmi-tones'foilow each other twice ir 
the chrbmatic.0rder'of the gamut.' - 
The elemcnta/'y route of.the fundamental baœs, to'produce an 
afcendant chromatic, is to deftend fi'om the third, antl afcehd to 
the fourth alternately, all the concords theraining the major thirdø 
If the funda,nental bali proceeds.. fr6m dominant to domlnant 
br pex'fe& cadences avoided, it produces a 'd½'fcendant chromatic. 
 o produce at the titme. time the one'.and the oth. or we intermi 
the perle& cadence, and" the interruption by avoiding them. 
As in every note the tone is changed in the chromatic, w 
muff: tt bounds and regulate thefe, thcceflions' for fear of luring 
our/hives; and for this-p.u,rp0fe, it mfift .be zernembered, that the 
/face which is moil: fuitable for the.chro. matic movement% is 
tween the dominant and tonic in afcendiixg and.between the to,- 
c H 6 3 
ale and dominant i-n defcending. .n the major mode we may 
alfo deœcend chromatically from the dominant on the econd 
note. Whis paffage is yery common in Italy and tho' beau- 
iful is rather too much fo in France. 
This chromatic is admirable for expreng forrow and ai&ion, 
its forcible founds in tiring Rrike the tbul. Itls not lefs energic in 
descending: We eem then even to hear the identical groans. 
;Vhen accompanied by its harmony, this kind becomes proper 
for every thing; but it fulnefs, by Rifling the air takes away a 
part of its expreffion, and 'tis then the oce of the movement to 
re,ore to it that which it is deprived of by the plenitude of its 
armony. Moreover, the greater energy this kind poffeffes, the 
leti ould it be augmented > Like thole del.icate difii's whole a- 
bundances loon difgu, fo it charms hen rudentt 'c6ndu&ed 
fo it becomes auated when overdone. . .

The time when the chriSlens began to have churches and to 
  phims and hymns there wa that wherein mufic had 
ready lo all its ancient energy, by a progrefs the eaures of 
'hich I have mentioned elfewhere. Tle chriians entering 
upon mufic in the condition whiclt they found it in, took from 
it even the greate rength that -had remained to it, that is to 
qy that of the rhyme and metre; when, inead of the vetres, 
to which it had Been always applied, they'changed it into the 
profe of their feered writings, or rome range kind of barbarous 
poetry, worfe for mufic than the profe itfelL In that care, 
of the two confecutive parts vaoies, and the air extending it- 
felf uni(ormly, and without any kind of meafure, from notes to 
notes almo $quat, lores, with its rhymlc and cenced form all 
the energy whkh it received from it. There were but a few 
hymns, in the which the profody and quantity of feet being 
preferred, we ill felt, in a leffer degree, the cadence of the 
verfe, but it was no longer the general chara&ers of the plain- 
ehant m gnerally degenerated in a pfalmody, always mono- 
tonous, and IBmcrimes filly, in a language fuch as the latin 
much lefs h3rmonious and accented than the Greek.. 
In fpite of all there fo great and fo effential loftes, the plain- 
chant preferred elfewhere by the priers in its primitive chara&er 
as well as all the exterior and ceremonious parts of their church 
ill pfes rome precious fragments of the ancient melody 
and its different modes to connoiffeurs, as much as it can make 
itfelf felt without meafure, and without rhyme, and in the only 
diatonic kind, which we can attribut in its purity to the plain- 
chant. The different modes therein preferve their two principat 
diinOions; the one thro' the diffgrence of the fimdamentals or 
the tooics ad the other by the diffct'ent petition of the tw 
fetal-tones, according to the degree of the diatonic natural fyf- 
tern, wheri½ the fundamental is 'found and according to what

melodious fyttems, efabtifled on pri'nciles different from ours: 
but we may well fay, that there is nothing mo,'e ridiculous and 
more flat, than there plain-chants fuited to our modern mufic, 
embellifhed with the ornaments of our melody, and modulated 
on the chords of our modes; as if our harmonic fyitem could at 
an)' time be united to that of the ancient modes, which is etSa- 
blifhed on principles ex;,t.%ly oppofite. We ought to thank the 
biflops, p,'evotts, and choritSers, who have oppofed this barba- 
rous mixture, and ufe our utnloit endearours for the progre and 
}3erfc&ion of an art, which is very far from the point at vhich 
t has been placed, that there valuable remains of antiquity may 
be faithfully tranfinitted to there who have fufficieht talents and 
authority to enrich the modern fytlem by the addition of them. 
How far foever our mufic may have been extended into that of 
the church, I am perfuaded that it would be preferable to convey 
he church mufic into ours; but for that, much tafte is neceffary, 
frill more knowledge, and above all, an exemption from every' 
kind of prejudice. 
The church' muœc 'is .pricked on four lines only, and there are 
but ttvo clefts ufed in at, i.e. that of ut, and the cleft of fa; 
one tranfpofition only, that is to fay, a B flat, and but two re- 
pr*fentations of notes, which are the long or t'harp, to which 
is rometimes added,'a tail, and the fhort which is formed as a 
lozenge. 
2kmbrofius, archbiflaop of Milan, is laid to have been the in- 
ventor oœ the plain-chant; that is to fay, that he was'the firfl: 
Who gave a form and rules to the ecclefiaftic chant, to fuit it 
better to its obje, and to defend it from the barbarity and ob- 
fcurity into'which mu/i½ was fallen'in his time. Pope Gregory 
perfe,fted it, and gave'it the'form which it preferyes at prelnt 
in Rome and the other churches, in which' the Roman melody 
is praetilid. The French church allows the' Gregorian chant 
but in part, with much ill-will and altooft thro' neceffity. 
The following extra froin a work about that time, printed at 
.Francfort in 59', contains the account of an ancient quarrel 
on account of the plain chant, which was renewed in 'our day, 
on mufic but which had not, God and king Charlemagne be 
praifed the lhme iffue. 
 The pious king Charles being returned to celobrate the 
{ feftival of gal'cer with our apefrolic lord at Rome, there 
 afore, dm%g the feaft,. a quarrel between the French and 
 Italian choristers. The Freach'prtended to ting better and

"his majefy, the French, who relied greatly on his partlallty 
"infhlted the.Italian fingers. 7'he.,v, proud. of their fuperior 
'" knowlcdee, and comparing the learning of St. Gregory to 
aa the uiicty of the others, treated them as clowns œools and 
a filly pretenders. As this alter.cation iill continued, the

"let dmvn in Italian Notes. Of'.theIE two chorifters, the king 
"on his .return into France, lent one to Metz and the other 
ß ' to Soiffons, giving all the mufic-mafters in the cities of France 
ß  orders to. give them.their Antiphonaries to correeq:, and learn 
' from them to .frog. Thus were the French :Antiphonarie 
"correed, which every one had changed by'additions and re- 
 trenchments a-œter his fancy; .and all the chorifters of France 
e½ learned .the,Roman chant, tho' they have now given it

inning of a fave to determine the degree of elevation of th 
ave in the general key and to exnrefs the names of all the 
notes which t contains wtlan the line of that cleft. 
Formerly the name of cleft was given to the letter br which 
the figns of the gamut were denoted. Thus the letter 2. wm 
the cleft of the note la; C the cleft of ut; E the cleftof mi, 
In proportion as the fyftem was extended they found the diffi- 
culty and the inutility of this quantity of clefts. Gui d'Arrezz, 
who had invented them, marked a letter of cleft a: the beginning 
of each llne of the fcale, for he had not yet placed the note 
within the fpaces. In iome little time, they marked only one 
the revert cteff at the beginning of one line only, that being 
Iufficient to fix the pofition of all the rope, according to their 
natural order. _At laft, from there revert lines or clefts, four 
were chofen, which they called claves fignate becaufe they were 
fatified with marking one on one of there lines to give the idea 
of all the others; in time, one of the four was removed; that 
is, the gamtna which they made ufo of to denote the fol 
vaz. the hypoprotlambanomenos added to the fyf'cem of the 
Greeks. 
Kiteher effeaually pretends that if we were acqalnted with 
the anci, ent writings, and urere to examine the figure of our 
clefts, e thould find that each one has a connexion with the 
letter a little varied of the note which it reprefents. For in- 
aance, the cleft ot: lbl was originally a G; the cleft of ut a 12 
and that of fa an F. 
We find then in the fifth three clef, one after the other. 
'rhe cleft of Fs ut, fa, or of fa, which is the Iowcf  th'e cleft 
of ut, or of C fol, ut which ia a fifth above the fir; and

COMARCHIOS,"A kind of appellation for the flute in the

COMMA, A /mall interval, wliich in rome cafes is found 
between two found% produced under the three dentnination by 
different progrefllons. 
We di. ftlngulfh three kinds :of commas. Fire% the minor, the. 
computation of which is from =o25 to =o48 , which is the qnan- 
tity by which tile 
a major third of mi, is fm-pafi'ed y' the natural nt whleh cor- 
refponds to it, This comma is the difference of the major and 
middle remitone. ß ' 
Secondly, The mor comma is that which is placed between 
tile mi produced by 'triple progreltion, as a fourth flftl b begin- 
ning by ut and the time mi, or its refpondenh confidered. as a 
major tlxird of that time ut. 'It numc'rical powcrs are .from 80

Thir.'lly, The comma maxhue, which is caIled tle comma 
Pythag'ora% has [ts computation from 50_40_88 to5344 , and it 
i the exceœ of the fi dieils product:d l)y triple progroton, as th 
tvelfth fifth of the ut on the three ut elevated by its eighth to 
the cotroll,on:lent degree. 
The muiicians u&ritand by comma the eighth or ninth part 
of tile tone, the half of a'hat they call a quarter of a tone. 
But we may reft. ariaed that they know not what they fay, ir 
expreffing the,elves thus, fince,. for eai's like ours, œo finall ar

Every eqv. al tone is cornpair.with the unequal that precedes it. 
COMPLEMENT Of an interval, is the quantity which 
wanting to it to arrive at tile oave, Ib tile fecond and feventh, 
t.he third and fixth, the fourth and fifth, are complements one of 
the other. Xhen we treat oœ one interval'only, complement 
tile fame thing with the general variation of notes. In regard 
to their kihds, the major is complement of tile lninor, the Ihper-

COMPOS'D, This word has three mea'nlngs in. mufic; twc 
in regard to the intervals, and one' to the mealufo. 
I. Every interval xvhich paffes the extent of the Oc"tave, is 
½ompos'd interval, becaut by removing tile ocøtave, we fimplify 
the interval witflout changing it. For inPtance, the' ninth, the 
tomb, and the twelfth, are compos'd intervals; the firit, of the 
thcond and eighth; the fecond, of the third'and eighth; the 
third; of the/;.fth and eighth, &co 
lI. Every interval which can be mufically divided into two' 
intervals, may be confidered as compos'd. By this means, the 
fifth is compos'd of tvo thirds; tl .thivd' of two feconds; the 
major fecond of two lhfitoncs; buith½, thmitone is by no roeany 
coml?ofed beeaul it can neither be divided on file gamut or by' 
notes.. 'Tis the fenfe of the difcourfe which out of the two fore- 
going acceptations mupt determine that according to'whlch ar. 
interval is compolhd.

The name of competition is nifo glvmx to the pieces of mufic

the duo, trio, quatuor, which I have ju roetaloned, are called 
comofitions.

for the in2ruments and the voice. Church-mufic and tbngsare 
the only compofitions which are for the voice alone, and to thot

of them. Irumental compofitions are for the choir of the 
orchera; nntl in that catb they are called tyrophonics and con- 
certs, or for lbmc particular kind of in.rmnenr, and they are 
then called pieces, fonatas. (Vide thole Words.) 
In regard to tle compofitio,s intended for the voice a for 
the inIb'nn'ents, tI:ey are generally di'idcd into two principal 
forts, viz. Latin or church-nufic, and Fr(nch mutic. The mufic

va-it.y of the bold andfwcet; or laRly, for adding t6 the mark'd 
ornaments thol which are fo neceffarily fuppofed by' the author, 
tha* no one can be permitted to omit them. 'Tis in vain for' 
a mufftiaa to be ingenious; tilere can be nothing concinnous 
but from the knowledge of the- mufic which he executes, and 
from the mutual underitanding that he maintains with others; 
for it would be impolfible to place a good concimw:ts in a concert

or forward their muficians in fixing throughout a good concin- 
airy, and this is what always form s a good firit violin,' by. a 
particular force in the execution, which impreffes frongly Its 
character on every ear. The reciting voice is fubjec"t to the baf. 
and m'eafure; the tirft violin fhould abvays attend to and follow 
the voice The lymphoar ou,ht to be attentive to the violin; 
and laly the harpfiehord, xvhiclt ve fuppofe to be held by tile 
eompol:r, flou!d be the true and firf dire&ion of the whole. 
In general, the more chara&er tile fi:il% periods, ph-ahs, an 
harmony poffefs the more eafy is the concinnous to catctb be- 
eaulb the lame idea impreffed with life on every mind, prefides 
over tile whole of the execution. On the contrarye.when the 
xnufic is fi'.ent, and we feel nothing more than a continuance of 
notes without an unlfon, there is no general object to which each 
ne connects his part and tile execution proceeds always in a 
dithgreeable ftrain. Fo9 this rcafon it is, that the Frer/ch mu- 
.tic is never concinnous. 
TO CONFINE THE HARMONY, Is to'cotle each part 
within the iinalleit intbrvals that can be poflible. For inftanc% 
to confine this concord, ut, tbl, mi which comprehends a tenth

(Vt4c DxssozqAzqc) producig a fourth found added to the

the ear fly the exclufioa of every other intervnI we ii:e from 
thence clearly their tburce in thtir generation. .11 
arl/b fi'om a perfe concord, produced by one only Fo,nd and 
the perfe concord reciprocal!y is formed by an aiFemblae of 
contbnances. It is therefore natral, that the harmon of this 
concord ould be commumcared to ts parts, that each of them 
thould partake therein, and that every other interval which docs 
not form a part of this concord thuld not partake init. Na- 
ture, moreover, which bas endowed the ollies of every nfe, with 
qualities proper for flattering it, has ehotb,, that one tbund, 
whatever it be, floutd be aceospanied xvith their agreeable 
tbunds, as fle has willed, that one rny of light flxoulcl be ahvays 
formed of the fine colours. But if we remove this quedion, 
and enquire whence arifes the picalure which a perfe concord 
caufes to the ear, whil it is diffused with the concourfe of 
every other fonnd what. can we anfxver .to that, unle to 
mand in our turn, why green delights the eye more than grey 
and why the odour of the role is pleating, whil the poppy's 
fmetl ditus'? 
I don't deny, but' that the'phyficlans have explained all this, 
and what is there they do not explain ? But hov much do thelb 
xplanations depend on conjeure, and how little folidity do we 
lind in them when they are nearly examined ? The teaclet will 
judge of this by the expofition of the chief of them, which l 
1hall endeavour at in as few words as poble. 
They tky, that when the fenration of the found is produced bv 
the vibrations of the fonorous body, propagated as far as th 
tympanum by th01h which the air receives from this ame body, 
xvhen two founds are heard together, the ear is affe&ed at the 
time time with their different vibrations. If thelb vibration 
are libchronic, that is to fay, if they agree in beginning, and 
finlilting at the ihme time, tlfis concurrence forths tle unitbn, 
and the ear, xvhich catches the concord of tbcfe equal and july 
concordant returns, is agreeably affe&ed by them. If tle (:ibra- 
tlons of one of the two lbunds re double in duration to thol 
of the other, during cch flattc vibration, the fliarp will make 
precifely two, and at the third they will let off together. 
Wheretbre every two'times each uneqhal vibration of the fliarp 
concurs with every vibration of the flat, and this frequent con- 
e0rdanee, xvhieh conitutes the o&ave, lcii fweet in their opi- 
qion tltan the unilbn will be more lb thn any othcr conib- 
0 z nanee. 
FR c o 
nnce. ' The {th comes after, one of whoœe œounds forms tw 
vibrations, whil} tire other forins three fo that they agree only 
in every 31 vibratio of thc fiarp; next ce the double. 
oSave, one of wh0b tbunds forms four vibrations, xvhil the 
other forms but one, agreeing only in every fourth vibration 
the arl): as to the Fourth, the vibrations anlkver cact other 
every fourth in arp, and ever}, third in flat; tho! of the ma- 
or hird areas 4and 5; of the maor fixrl a 3 anti 5; ofth

Al'.ot'e thot numbers there are only their multiples, which pro- 
due:. confonances, that is to fay, tge o&aves of the former: all 
the remaining parts are diflbnant. 
Otler finding the o&ave more agreeable than the unifon and 
the tilth more agreeable than the oaave, give it as a tea Con, that 
tIe equal returns oF the vibrations in the unifon, and their too 
frequent concurrence in the o&ave, confound identify the founds 
and prevent the ear frown perceiving their dvedity. That 
may fe'et the founds with pleafur% they fay that it is neceffary 
for' the vibrations to accord by intervals, but not for them to 
Confound each otker too often  otherwif% inead of two founds, 
we ould think to hear one only, and the ear would lore the plea- 
lure of the comparifon. 'Tis in this manner, that from the fame 
pdncipte we deduce, according to 0r liking, the pro and con 
ju as we imagine that experience requires, 
But in the fit} plac% all this explanation i as we may fee, 
founded on the plealure only that we pretend the foul rcelveu 
ebro' the organ of hearing from the concurrence of vibrations 
which at bottom, is nothing more than a mere fippofition. 
loreover e mu again tUppol to authorire this fyem, that 
the firff vibration of each of the two ibnorous bodies begins 
exa&ly .ith that of the other; for, however little one may 
precede, they o longer concur in a determined conne&ion, per: 
haps even they can i, no catb concur and contquently tha 
fenfible interval m,ff be ih}eed to change; the conIbnancg 
co:,:d no ionget exit, or at lea would be entirely diCereat. 
Lafiiy, we ma fuppofe, that the different vibrations of the 
founds of a conlbnanc 9rike tle organ witleone confuti0n and 
tranlinit to the brain, the bnthtion of the concord, without a

concords afford me, the effe& mu be poportion.ate to th

plealure and pain then cannot be derived from thence. 
It ill remains to y attention to the alterations of which 
a confonance is "futeptibl% tho' tllel alterations. mirplace 
titely the periodical concurrence of vibrations; and tho ncur- 
renee itlhlf becos more fcarce in. proportion as tho altemd

According to this author, and Dcœcartcs ah%, the plealure dimi- 
nishes in proportion as thelb conneious become mm'e compolbd, 
and when the mind partakes in them no more, they are veritable 
diffonance; wherefore it is an operation of tle mind which 
they take as the principle Of an harmonic fenriment. More- 
over, though this hypothetis may agree with the re/hit of the firff 
harmonic divHions, anti tho' it may extend itiblœ even to other 
ptmenomena that are dilbovefed in the fine art% as Jt is (ub. ie to 
the farne obj'cuC'tlon as the precedbg, it is not pofl]ble for reafon 
to render a fatifaory account of it. 
That of all, which appears the moff fatisfaorv, has for its 
author Monl Efve, of the Royal Society oœ Montpdlicr. 
Here are his reafonings thereon: 
The fentJment of 1bund is infeparable from that oœ its' har- 
monlcs; and tince every found bears its harmonics, or rather its 
ceompaniment with it; this fame accompaniment is in the order 
of our organs. There is in the moff fimple found, a gradation 
of founds, which are fharper and weaker, which fweetcn, by 
thefr vkriety, the principal /bund, and render it 1of'c in the great 
velocity 'of the higher founds. Here then ve fee the explana- 
tion of a found; the accompaniment is effential to it, and forms 
its iveetnefs and its melody. Werefore, every time that this 
œweetenlng, this accompaniment, there harmonics are enforeed 
and better difclofed, the founds will be more melodious, the va- 
t;cries better fuained. This is a perf½c"tion, and the foul ought 
to be fenlibte of it. 
The confonances, moreover, have this propriety, that 
harmonics of'each of the two founds, concurring w;th the haft' 
reonics of the other, their harmonics are mutually fufaJned, 
'become more fenfihle, have a longer duration, and by this means, 
make the concord of tbunds which produce them muel mor 
agreeable. 
To make the application of this princ3ple more evident, Monf. 
Ett6ve has formed two tablcs the one of confonances, and the 
other of diffonances, which are in the order of the gamut; 
and there tables are lb difpofed, that we may perceive in each' 
the conc.urrcncc or oppofition of the harmonics of the two tbunda 
which rm each interval. 
By the talkie of the confonances, ve fee that the concord of 
ouave preferyes at,no all its harmonics, and this is the teafort 
of the identity which xve fuppofe, in the pra&ice of hannonr, 
to'be between the tvo founds of the oc"tave: we te that tile 
concord of the fifth prellryes three harmonics only; that the 
fourth bas only two; and laf'cly, that the imperfe&' confonance, 
prctrvcs but on% except the major fixtit, which bears two. 
'C 0 
]2y the table of diffonances, we fee that they prefcrve no kind 
of harmonic, except the minor ihventh .',lone, which preferves 
its harmonic fourth, that is, tIe major third of the third oave 
of fharp founds. 
From thelb xbfervations, the author concludes, that the more 
concurrent harmonics tIere are between two ibunds, more will 
the concord be agreeable, and in this confirm. the perle& conib- 
na[Ics. 
The more harmonics there are deitroyed, th lefs will th foul 
be ttisficd vlth its concords: Such are imperfe confonances. 
La.ql¾, if it fhould ever happen that no harmonic is pretkrvcd, 
the ibands vill be deprived of their fweetne and melody,' they 
will be difagreabl, and rndered, as it were, thin; the foul 
will be difgufted with them, and infead of th harmonious 
fweetnefs, which it difcovered in the confonances, finding nothing 
but a continued roughheYS, it muflt feel a fenration of inquietude 
wy difagreeable, which is the ffe& of diffonances. 
This is, without contradition, the happieR, moi fimple and 
,nor natural of every hypothefis, but it f[ill leaves tbmething 
o be wifhed for the fatisfaion of th mind, œmce the eauYes 
which are afligned are not alway. s in proportion to the differcnc' 
of the effecCts; as, for inance, it confounds in th fame cathe- 
gory, the minor third and th minor feventh, as equally reduced 
to one harmonic only, tho' the one is confonant and the ether 
diffonant, and th cffe, to th ear,-is as different as pof- 
iible. 
In regard to the principle imagined by Monf. Sauveur, which 
he made to confi it the trokes, as it can by no means be fur- 
rained, and has been adopted by no one, I will not employ it 
here, as it will fnffice to :lirec"t the reader to what I have fpoken 
of it under the word Beatings.

COPIER, He wholb profelon it is to copy marie. 
l-xto:v great a. progreti thevet tire art of typog'aphy may have 
made xvc have nc'er been able to apply 'ic o marie with tb 
great faceeli as to writing: wl'.ethcr it be becaulb the taite of 
the mind being more f'cable than that of the ear we are not 
œ0on tired with the lhme books as with tile fame lbngs, 0r by tlre 
particular difficulties which the combiaation of the notes and 
lines add to the imprefllon oœ mufic; f)r if we.draw firft the 
lines, and then rlrc notes, it is impoffible to give thclr relative 
pcfiti0ns that juf'cneti which is neceffary; and if the characCter 
of each note engroflbs a portion of tile fcale, as in our printed 
m'fi% the lines are fo milrably adjutted together fo great a 
quantity of chara&ers are requircd, and the whole produces tb 
di:itgreeable an effecøt to the ear that this meth0cl bas been abo- 
lfied wtn real'on, and the engravn= lxas been fubilituted in its 
place. But betides the other inconvenlencles that engraving is 
thb.e to it has particularly that of augmenting too much or too 
little tile examples or parrs; of placing in partiti,on what rome 
would chufe in feparate parts; and in feparate parts what others 
would chufe ro be in partition; and lailly of offering to the 
curious nothing but ancient muff% which has pawed thro' the 
hands of half the world. It is certain, that in Italy the country 
which produces the g'eate variety of mufic, they have abolithcd 
œome time the printed not% without the engraving having been 
able to eilablith itfelf; from whence ! conclude, that in the 
nlon of the ingenious that of the fimple copy is the moil .pre- 
trable. 
It is of greater importance, that mufic fixould be corre&ly and 
neatly copied than tlmple writing, becaufe he who reads and re- 
ttlc&s-in his elofet, ny eafily corre the errors of his book, 
whil nothing !revents Itim from furpending antl re-beginning Iris 
difcourli; b'in a concert, where each one tes but his part 
and where the velocity and continuance of the execution leave no 
time for re&if ing any error, 
ß y. they are all irreparable; a mot: 
rublime paeee as often murdered the execution is intcrrupte.d 
and even ttopned; every thin oes contrary, the effect and unx- 
fort fails thrc;t{ghdut, thg heaer'is difgutted; and the author dit:- 
courttenanted thro' the error only of the copier. 
Moreover, the underilanding'of a difficult piece of mufie de- 
lend greatly on the manner of its being copied, for betides the 
'neatnet in the notes, there are different meth94s t.o repr.ef. ent 
more clearly to the reader, the ideas that we would paint to 
and which lm Ilxould underRand. We often find the copy of one 
94 C 0 
man more legible than that el' anot!',er, t!:o' the latter may prick 
his notes' more a,reeably; the ca. of which is, that tile one 
xvill;es to plea!i: the eye, whJiil the other is attentive to more 
œerGceable en.leavours ! 
Tile moil ingenious copier  he  hole mufic is elxecutcd With 
the moil: eatb, whhout the muficians perccivin5 ever the real-on 
whv.'.All this has perfuaded mc that [ fhould not compile an 
mfeœ article, if I demonfh'ated in brief an account of the dnties 
and cares of' a go,,d copier. Every tiling that tends to facilitate 
the execration, is by no means imli'ff.crcnt in tire perfeXion of an 
art, of which it- is always the mof'r material beauty. 1 r tYel how 
much I fhaltinjmemv!elf if my works are com!*arcd with my 
rules; but I am not ignorant that he !,v!:o lbek the public uti- 
lity, fhould never have a remembrance of his own. As a man of 
letters, I have tiaoken of roy condition all the evil I think oœit: 
I have compothd French mufic, and love only the Italian; I 
Eavc ::wn all the ditidvantages of' tbciety, at the time when it 
gave me a fiticere plealure; as a bad copier, I Irere dcmonlkrate 
tile laws ',,y whiclz the :ngnious are d/re&ed. O truth! my 
intcrd3 acre:- prevailed in opFofitlon ro thee, and may it never 
in any reœpe& eralb the admanion xvhich I oxi'e to thee ! 
I nhuft primarily fuppolb, that the copier is poffeffed of all the 
knowledge neceffary to his profefilon. I even flappole him en- 
dued wih the talents neceary for a fuperiority in its perform- 
ance. \Vbat ae there talents, anti what is this knowledge? 
Without ab.,lutely delineating tlem, I can, uuder this head 
oive a fufficict:r idc. of them. All that I am privileged to fay 
here, is, that t!:e corn?offer who thinks hlmIbtf ingenious, may 
be very tT;!r from being thfficiently tb to copy corre&ly the com- 
pofition oF another. 
As written muric, particularly in partition, is made to be read 
by concertants at a dif'cance, the chief thing to be obferved by 
the coplcr, is to make utb of the convenicnmateriats for rendering 
his notes too2 neat and legible. For this reafon, he fi'iould 
½hufe ecrong fair paper, rather tliin, and xvhich does not rink; 
{hat which does not require waftting is genorally preferred, be- 
cauœe the waffling with xllum takes off' i=)methifig of its whi'te- 
nctk. The ink ought to be very black,'without either glofs or 
,um; the ruling lieat, equal, arid well fixed, but nor fo blac. k as 
the notes; on thc contrary, the lines fimutd be rather pale, fo 
titat the crotchYts, dou'bte croichets, paufes, and 'other finallet 
Jigns ma i, not be confounded with them, and'that the note may 
bc expretFed the fuller. The palcacti of th6 lnes; 'far from pre- 
Venting the mufie to be read at a fixdd dlecance, on the contrary, 
afliiN it by its neatnetS, and tho' the line fhoutd now and then 
½lcape the fight for  moment the pofition of the notes very 
ß of tea 
c o 
often ofltCelf de.otes it. The ruling of the paper is but an 
labou?. If the copier would gain himfell credit, let hin rule 
paper himilf 
There are two fonation for ruled paper, one for the 
instic, the lcagth of which i fi'c'n the l,)ttom to the top; th 
othcr for the [c.tI]1 b the Ica'th of' which is according to the 
rcon of th:.lhes. X.Vc may make ul of the fame paper for 
tbc two, b>, cSppingan:l rulin?{t contrary ways; but whcx we 
buy it rifled we mu change the nmcs at the paper-fellers, and 
az for Irali;m paper when wc. want the French, and Frenc 
whenwewant It:.;an; thisqui pro quo is of little importance 
when weare acquqinted b:fort:-hand. 
To copy a pai'tition, we mu rcckon up the parts which the 
fcalc ccmprehcnds and choofe paper which has by the page the 
lhrne number- of Ravei or a multiple of that number; finally, 
we ould loI no av% or at lea, as little as poffible when the 
multiple is not exa&. The Italian paper has generally ten 
Raves, which divides every Fage into two columns, each of five 
aves for the ordinary airs, that is to fay, two fiaves for the 
two treb:es of the violin one for the fifth one for the air, and 
one for the BaYs. When we have duo's or pieces of mufic for 
fiute, hautboys horn% or trumpets ih that care, to that number of 
aves we can put no more than one column in the .pag% unlefs 
we can find a method for fuppreffing fome ufelefs av% as that 
of the fifth, when it is continually m motion on the bays. 
Herein, however, are rome obfervations, which we ould 
'make to diribute the partitions with exa&nefs. Fir, what- 
ever number of parts' of/ymphony we may hay% it is always 
neceffarv that the parts of the violin, as being principal, thould 
be plac(d at the top of the column where the eyes may  mo 
eafily conveyed. Whole who place them at {he bottom of all 
the re and immediately on the fifth, for the convc,fienc of 
the accompanimenq am in an error without obferving that 
is ridiculous t0 fee in a partition the parts of the violin below 
for infiance thole of the horn which are of a much deeper 
bays. ' Secondly,' in the whole length of every piec% we ought 
never to change any' thing in the number of the par% fo that 
very part may have its properties in the fiune place. 
It would be better to leave the aves vacant or if there is 
necetty, place two parts in rome of them than to extend or 
iliminifi the column unequ'ally' This rule is for the Italian 
mufic only, gr the ufe of engraving has nade the French mue 
mora attemi...., to the moohorny of the fpac% than to the com- 
modity of the: execution. 'Thirdlye' it is only at the greate 
extrcmit that we fiould place twopa?ts on the thtncRave, and 
this is what we ought particularly to void in thu parts of the 
violin 
rloin  for,. betides tha here is much confutlon to le fearcog 
ihere would be an equiyocation witlx the doulle chord; we 
/nu always filfo be kareful, t]kat the parts do not interfere crofs 
way% which we could not expreVs on the fame ftave, in a me 
thod.elefir and legiblei Fourthly, the keys being correctly writ- 
tdn, .and once numbered, /hould'-never be repeatell ;ny mo3e than 
/he fign of the meafure,. unleœs in he French muff% when, tile 
golumns. being uequal, each one could noi recolic his parts; 
but ;n the fepaYated parts, We mu repeat the cliff at the begin- 
ning of' each fffve, Wet4 it onl'y to' denote tile beginning of the 
lines, on a fa51ure of the colutah. 
The ffum)er 6f flares feing thus fixed, ;ve mu make a dlvlfion 
0f the meafures and there mefures ought t0 be all equal in t]ace 
as w11 as duration, to meafure in œome refpe the time by the 
eompafs .and to guide' 'the voice by the eyes. This fpace onglt 
tO be' fuficiently extended in each meafure,..to receive all the 
notes which cdn enter fherein, a4cordin_ to its greateft fub-divi- 
/]on. It carlnot b ;magined how gre a clearnet this cave 
throws on a partition, and in What an embirraffment a negle 
of it th'rowt them. If we confine g meafure on a crotchet 
how can We place tiie fixteen double crotchets, which, perhaps 
andhex;part contains in the /'ame meaœure. If we confine our- 
/'elves to the vocal part, how can we fix the fœace of the returns ? 
.In'a word if we are attentive only to the divlfions of one of 
there prts, how can We make the divifions of the other parts 
often'contrary to coincide with them. 
It is not fufficient to divide the air into equal meafures, we 
muit alfo divide the meaœures into equal times. If in each part 
we proportionate thus the /]ace to the duration, all the parts 
and ill'the fimultaneous notes of each part will correœpond with 
a julinch which will give lealure to the eyei and will greatlr 
l:illtate. the reading o.f a partition. If, /or in./tanc% we divide 
' a meafure into four umes into four fpaces very equal together 
and in each part, if'we extend the crotchets draw. the quavers 
nearer, and confine the femi-quavers in proporti?n and each in 
its/'pace, without wanting to look at one part m copying ano- 
ther all the correfpondln/ notes will be more exaly-perpendi- 
cular than if they had been confronted by writing them, whether 
between.the different meafures of the fame part or between the 
different parts of the fame meafure. 
To the exalthers of the conne/lion% we muf join as much a 
poffible, a neathels'in our figns. For i'nfta'nc% we /hall never, 
prick ufelefs notes { but as loon as we perceive that .two notes 
re-unlt% and are m unilb% we ought to œeparate the one from 
the oder when they are near caclf other, and on the œqme elifl'.

LaPely, It is the duty of a copier, when 'he svrlresz pavi41tion to

contlPcs in readering faithfully the iTieas of the author; good or 
ill that is not Ids-bufinetk,-fince he is neither author or col

but f ths fhme author ias throu.l zõnoranc'e, ade an error 
in the compofition he fhould leav it.-Let him ,:orrrpoii better

he thould have an eye to his m,[gial. We tke by this means, 
that it is not fufficicnt tbr a coper to be a good ha;monift 
to.undm-Pcand well the compofition hut he fhould, into the bar- 
g.;n be well /killed in the different ftyles and be converlhnt 
in an autlor by his method to know vhat he has, and what he 
has not compof'ed. There is, moreover, a ki_nd of criticilin 
neceffary to reftore a naffae by the comparifon of another, to 
replace a forte or a dolce where xt las been om:tted, which xs mat 
nncommon in tke partitions; even tO dlfunlte alfo phrais im-

Before ! finifh what appertains to thepartitions, I muff fpeak 
of the method of colletting the feparatedparts; a laborious talk 
fi'om many copiers, -but fimple and eafy when we undertake it 
by merhod.Vor this pu..'potb, we muff fi,'t reckon carefully the 
meafures in each part, to-htisfy ourfelves that they are co?tee'}, 
Then we place all the parts one on the other, beginning hy the 
bars, and covering it fuccelllvely with the other parts in the lhme 
order as they ought to have i, the partition. We cornpole the 
columns of as many flares as titere are parts, divide them into 
equal meafires thn placing all tittle parts thus ,'anged before 
u, on the left hand,,we firit copy the firff line of tile tlrff part

cther all lhe parts wMcl were changed one on the other on 
ihe right hand, and xxe once again change thmn n the left; 
they are then found in tire fame order )tl jn the fame fituatlon, 
as when they began: we then bcgn the fecond column at the 
pencil mark; we make another mark 'at the end bf the tcond 
line, and we c.otinue as before till the whole is completed. ' 
I thall have little to thV on .the axeflOod of 3rawing a partligon 
into fepaat parts, for ihls is th mo fimple operatiqn of th& 
ß are, nd i will b fufficient to make therkbn the foll.6wing 
fervat[ons. Fir we mu fo compare the length of the pieces 
to what a pge may con[M% as never to be obliged to turn off 
, hme piece in inffrumentaI pas; u01eFs there arb a grea 
un.berofmeafue?'to reon, whi.ch will"fford time. This 
rule obliges us to begin at the page verfo all the pieceb whicli 
akes up'bore than a pag% and there are none which fill more 
than two. Secondly, the dolce's and the forte's fl{ould be marked 
-ith the greateft exa&ncfs on all the parts, even thoe where the 
air begins and finics} which are'not ordioarly on the partition. 
Thirdly we ought never to divide a mehfure frome Qae line tb 
.another, t:t endearour that there flould b always a bar at th 
end of tack flare. Fourthly all de additional lin which ex- 
eed citcr above or bclow the five of the flay% ould' by no

'rule is not lt neceffaryin the 'partitlonk, and is followed, how- 
cvcr by no French copwr. Fifthly, tlie prts of the hautbo 
.which arc dravn' 9n 'the parts of tle violi'n for a full band' 
Jhould ncx'cr be exa&ly copied as the are'in the original, but,

This term of couter-point is dcri'ed from wtat in ancient 
.tinms the notes or figns of founds were with fimple points, aneI 
)rt compofin there with many parts, there poi0t  were place& 
ever each other, or oppfite. 
At pretknt, the name of counter-point is efpecially aptlied te 
lhc parts added on a given ful, jeO, taken ordinarily front the 
mufic of the church,. The thbje& may be in tenor, or fom½ 
bthcr fulerior part; and in that care we tay hat th& counter- 
point is below the thbje&; but it is generally in th bat, whiclt 
places the t'uhie& below the countm'-point. When the.cb. uner2 
point is fytlablc, or note ppon note, it is called fimpl 9oUnterv 
point; figured counter-point  when there are found differen.t 
gures or po'eri of the notes, and when there are formed defigns 
fugues, or imitations. We eatly fee that this cannot be'done 
but by affiftance of the meafure, and that this church melody 
then becomes a true mufic. dk compofiti.on formed and inffantlr 
xecuted, without preparation, on a given œubje, is called al 
niL' at fight, becaufe then each one eompofes extempore his part 
hntt his air on tle book of the choir.

End of the Table of Cyphers. 
Some authors had introduced a curlorn of covering with a 
Rroke, all the notes of the bat which puffed under the fame 
concord: In this manner, the pleating cantatas of Monf. Cle- 
rambault are cyphered, but .this invention was of too much uti- 
Ety to continue; it fhewed alFo too clearly to the.eye, all the 
fyncopes of harmony. At pretent, when the Fame concord is 
fuRained on four different notes of the bars, there. a're four dif- 
ferent cy hers which they are obliged to bear, fo that the ac- 
companiR, led into an error, s haienmg even to feek the con- 
cord which he has under his hand. But it is the fa/hion in France 
to load the bafs with a confufion of ufelefs cyphers; every thin 
is cyphered, even to tile mof evident concords: antl he who ' 
placs the greatef number of cyphers is rc'ekoned 'the mope inge. nious. A bafs thus confufed with trivial cyphers retards he 
accompanifc, and often makes him negle& the neccffary cyphers. 
The author I think mu thppoth that the accompani 
knows the elements of accompaniment that he knows how to 
place a fixth on a mediant; a falfe fiftl on a fcnfible not% a 
iventh on a domiant &c, he ould not therefire cypher 
there evident concord% unlel that it be neccflhry to announce 
a than e of the tone The c phers are made only to determine 
the choice of the 11arony m dbous cales or the choice of 
founds in the concords WhicI ought not to be filled: otherwit 
it is very well to have eyphered ballks for IHxolars only. Cyphers 
mu e' them the'ap 'llcation of the rules; as for tl;e macrs, 
 Is !ufficaent tO fpecffy the exceptions.

this feale, fuch z it is at prefent, is neither exa in regard to

The diatonic genus  without cntradi&ion, the mo ha-. 
tral of the three, fince it is the only one which can be ufed 
without varying the tone. It intonation alfo is incomparably 
more cafy than that of the two others; and there is no doubt 
but that ,the fir& fong were compofod in this kind; but we mu/ 
obferve, that, according to the law of modulation, which permit 
and lefcfibes even the Paffage from one tone to another, we 
have no pure diatonic in our mfic. Each particular tone, I will 
allow, in the diatonic, is good; but we cannot pals from one 
to the other without rome chromatic tranfition, at leatt, an omif- 
fm of the harmon},. The pure diatonic, in which no one of 
the founds ia altered, either by the cleWor accidentally, is called, 
by Zarlin, dlatoao diatonic, and he givea the church-mufic as an 
example. If the cleft is numbered with a B flat, in t.hat catb, 
acr. ordiag to him, it is a flat diatonic, which mutt not be con- 
founded with that of Arittoxcncs. (Vide Fr. aT.) l.n regard 
to the tranfpfition by_ diefis, this author fpeaks nothing of it, as 
it. had.aot bern praEtlfed in his time. Doubtlelh Ie would have 
given t tim name of rough or /harp diatonic, tho' there had even 
refultcd from it a minor ,node, as that ,f Ela mi, for ,n thole 
times, when they had not thc harmonic ideas of what wc 6all

DIATONIC SOLNDS or CHORDS. Euclid dlf'dnguifhes 
nder this name, amongi the moveable founds, thole which do 
not partake of the greater genus, even in the chromatic and en- 
harmonic. There founds in each kind are five in number, i.e. 
the third of each tetrachord; and they are the fame which other 
authors call apycni. (Vide APYCl'I, GIII$s, TETRACHORD.) 
DIAZEUXIS, A Greek word which figriffles divifion, ipa- 
ration, disjun&ion. 'Tis by this term that the tone which fepa- 
rated tvo tetrachords disjoined, was called in ancient mufic.. and 
which being added to one of the two, formed from it the dia- 
pence. It is our major tone, whole reference is from 8 to 9s 
and which in effe is the difference ot the fifth and fourth. 
The diazeuxis in their mufic was placed between the mefis 
and paramefis, that is t0 fay, betwe,n the fharpeit tone of de 
fecond tetrachord, and the fittefc of the third, or ot}erwife be- 
tween the note fynnemenon, and the paramefis hyperboleon, i.e. 
between the third and fourth tetrachord, provided that the dif- 
juneion was formed in the one or the other, for it could not be 
pratired at once in the two. 
The homologous chords of the two tetrachords, between which 
there was a diazeuxis, founded the fifth, whereas they founded 
in fourth when they were conjoined. 
DIESIS, Is, accordinz to old Bacchiu, the fmalle interval 
of the ancient mufic. Z'arlin fays, that Philotaus, the Pythago- 
rean, gave the name of dieils to }he limma; but he adds, a little 
farther, that the dieils of Pythagoras is the difference between 
the limma and apotome. As'to Ariitoxenes, hedivided the tone 
into two equal parts, without many variations, or in three or 
four. Fro,a this luff: divifion rfulted the dieils, enharmonie 
minor, or fourth of a tone; from the fecond, the minor chromatic 
dieils or third of a tone; and from the thirds the major dieris s 
which made exactly a demi-tone. 
DIESIS, Amongft the moderns, is not properly, as amongi 
the ancients, an interval of mufic, but a fign of that interval 
which fpecifies that we muit faire the found of the note, before 
whkh it is placed, above that which it ought naturally to have, 
without, however, making its degree or name undergo a change. 
Moreover, as this elevation may be made, at leait, three way 
in the ettablifhed genera, fo there are three forts of dieils', viz. 
Fid}, the enharmonic minor, or timpie diefi, whole form is 
like St. Andrews's Crof% accordin_.- to all our muffclans, who 
tollow the .pr.aCtice of Anfoxeues, t rmfes the note the fourth 
of a tone; but properly it was only the excels of the fetal- 
to.he major on the femi-tone minor. Wherefore from the 
natural 
D I 
natural ml to tl.e fa B flat, there is an enharmonlc diefis whole. 
numerical powers are from 25 to 
Secondly, The chromatic dieds, double or ordinary' dieflsa 
marked by a double crofs, raits the note a fetal-tone 
minor. This interval is equal to that of the B flat, i.e. the 
difference of the major to the minor fetal-tone; wherefoi'e, 
aftend from a tone beyond the natural ml, we mui'c pals to 'the 
fa dieds. The reference of this dieds is from 24. to 25. (Vide 
on this artlele an effential remark at the word fetal-tone.) 
Thirdly, The enharmonic major, or triple dieds, marked by' 
atriple crofs, raifes, according to the AriRoxenians, the note about 
three fourths of a tone. Zafiin fays, that it rail'es it a remi- 
tone minor, which cannot be underfcood of our femi-tone, finee 
in that care, this dieds would be exaftly timilar to our chromatic 
dieils. 
Of there three dieds', whole intervals were all pra&ifed in 
ancient mufic, there is only the chromatic which is ufed 
ours; the intonation of the inharmonlc dieds' being to us 
almof'c infurmountable difficulty, and the ufe of them being alfo 
abolithed by om fyftem. 
The dlefis, as well as the B flat, is always placed on the left s 
before the note which ought to bear it; and before or after 
cy her, it fi hides the fame thine as before a note. (Vide 
P g 
C¾,t-xg. ws.) The dieds' which are intermixt with the c)/pher 
of the thorough bar's, are often no more than timpie croWes, 
the enharmonic dlefis: but this cannot caufe an equivocation 
fince it is no longer in ufe. 
There are two methods of making u['e of the dieils. The one 
accidental, when, in the court of the air, we place it on the 
left of a note. This note, in the major modes, is moigenerall. y 
1ound the tourth of the tone: In the minor modes, two acco 
dental dieds' are mo commonly neeeffary, particularly in 
cending, i.e. one on the fixth note, and another on the feventh. 
'The accidental dieils changes only the note which immediately' 
follows, or, at the mot, thole which in the fame menlure are 
placed on the fame degree, and rometimes in the o&ave, without 
any contrary fign. 
The other method is to make uf'e of the dieds in the clet 
and in that cafe it is carried tbro' the whole Continuance of the 
air, and on all the notes which are placed on the fame degree 
whereon is the dieds, unlef it is oppofed by rome B flat or tharp 
or that the cleft has no changes. 
The pofition of the dieds' in the cleft ia by no mean arbi- 
trary no more than that of the B's fiat; otherwife, the two 
U  fetal-ton, 
D I 
fetal-tones of the o&avc would be fubje& to be found together 
out of the prefcribcd intervals. Wc mu then apply to the 
dieils  a timilar reafoning to that which we have made at the 
article B flat and it w[11 be found that the order of the dieils' 
which is fuitablc to the clcff is that of the following note% 
beginning by fa, and aœcending tucceffively by fifths, or deœccnd- 
ing by fourths as far as the la at which we generally op be- 
caufe the dieils of mi which would follow, does not differ at all 
from the f; on our fi:ale. 
Order of Diefis' on the Cleft. 
Fa, Ut, Sol, Re, La, &c. &c. 
We muf take notice, that a dieils cannot be ufed in the cleft 
Without ufing alfo thole which precede it; wherefore, the diefis 
Qf ut is placed only with that of fa; that of iol with the two 
leceding &c. &c. 
I have given at the article Tranfpofed cleff a formula to find 
immediately if a tone or mode ought to bear dlefis' in the cleft s 
and how many. 
Such is the acceptation of the word dlefi% and its uf% 
pratice. 
The mot ancient manufcript, wherein I have feen the 
tffed, is that of Jean de Muris, which makes me imagine itmlght 
have been his invention. But it appear% in his example% to 
have only the effect of B flaarp; and this author alfo gives the 
name of dieils always to the major fetal-tone. 
In harmonic calculation% we call dofis' certain intervals s 
greater than a comma and tefs than a femiotone which make 
th difference o other intervals engendered by the progreons 
;and references of the con!onances. I'here are three of there 
dieils'. Firf, The m.ior diefis which is the difference between 
the major and nilnor tmi-on% and whole numerical powers arc 
from l:z$ to z8. Secondly The minor diefis which is the 
difference between the tnfi-tone minor and major dieils, and in 
reference 3072 to 325. Thirdly, The dieils maxima, in nu- 
merical powers lrom 243 to 45o which is the difference of the 
minor tone and greater emi- tone. 
It muff be confefFed that tb many different acceptations of 
the fame word in the time art, are only a eaufc of frequent 
etluivocations  and produce a continual confufion or' errors.

DIMtN[SH'D, A dlminifl'd interval is every minor interval 
irrom which a tmitone is taken by a dieils to the inferior note, 
or by a B flat to the fuperior. In regard to the .iu{'r intervals, 
formed by perle& confonances, when they are dlminifl'd a femi~ 
tone, they ought not to be called diminifh'd, but fall; tho' it 
is often fa'id, mal-a-propos, a dilninifh5t fourth, infiead of favino' 
falfe fourth; and dmxmfhd otav% rot'read of fay rag falte

DIMINUTION7, An old word, which fignified the divilioa 
of a long note, as a rainurn, or crotchet, into many other finallet 
notes of leffer powers. It was alIb underfl:ood, that this word 
expreffed fixore terms which' we call by the denomination-oœ 
trilI or quavers. (Vide thot wods.) 
DIOX¾, Is, with reference to Nicornaehus, a name which 
the ancients gave rometimes to the confonance of the fifth, 
which they more generally called diapente. (Vide D~ 
PENTE.) 
DIRECT, A di'e& interval is that which fOrrs any kind of 
harmon on the fundamental found wlfich produces it. Where- 
fore, the fifth, major third; and the o&ave, wxth thexr reddroves, 
are rigorcurly the only dire& intervals; .but by extenfion, we 
call allb dive& intervals all the reft, as well confonant as diffo- 
nant, which each part forms with the pra&ifed fundamental 
tbund, which ought to be below it, Wherefore, the minor in- 
terval is a dire& interval on a concord.in third minor,.and in the 
fame manner the thventk or fith added on the concord whick 
bear their name. 
A dire& concord is that wifich has the fundamental found in 
fharp, and whot parts are dirihUted, not according to the moil: 
natural order, but according to the mof confined. Wherefore 
the perfe dire& concord is not oav% fifth, and. thirdi but 
third, riftlb and o&ave.

Among us, the name of diiolnt is given to the intervals which

coms'd of two or more conjoint degrees, are alfo called dit

xvas a tone, and was eatled in Greek dlazeuxis.

Whe ancients ever/ counted as ruth, the thirds and fixths, which 
they cut o from the confunfint accords. 
The' te diffofianee is. Strived from two words, the one Greek, 
tile other Latin, which fignify a double fonnd. In effe'&, what 
renders th onance difagreeable, is, that the founds whick 
trm-it, far from uniting. themf8lves to the ear, rike again

The'name of interval is vea fømetlmes to the. interval, and

D I 
All the conf'onances arife from thenc% and it is nature it/elf 
which furnifhes them. The diffonace proceeds on a different 
plan, at lea, thch as we pra&ice, 
We allowedly find its generation in the progreffions of confo- 
nant interval% hnd in their differences, but we cannot difcover 
any ptyfical realbn which authorires us to introduce it in the 
body itfelf of harmony. P. Merfenne contcnts himfell with 
fiewing the generation by calculation s and the diffeeent connec- 
tions of diffonance% as well of thole vhich are reje&ed as of 
thole added  but he mentions nothing of the laws for ufing 
them. Monf. Rameau fays in formal term% that the diffo- 
nance is not natm'al to harmonys and that it cannot be ufect 
therein xvithout the affifcance of art. However in another work 
he endearours to find its principle by nmnerical powers and har- 
monic antl arithmetical proportions, as if there Avere any identity 
between the proprieties of. the abfcracd quantity s and the œen- 
fations of hearling. 
But after having xvaied a quantity of analogies, after anum* 
ler of )qetamorphofca of thclh diffcret proportions, the one 
witliu the other, after numerous opcratious, and utlefs calcu- 
lations, he fimfics, by eftablithing, on trifling connerions s that 
diffmance which hc gave hintfelf fuch unwearied pains only to 
cliff:over. $Vherefor% bccaut in the os'der of harmonic founds 
the arithmetical prbportion gives it by the lengths of the chords 
a minor th3rd in flat, (take notice that it gives it to the fhaFp 
by the calculation of vibrations) he adds to tlxe flat of the fub2 
'dominant a new minor third. The harmonic 1)roportion gives it 
a minor third in iharlb (it would give it to the fiat by vibra- 
tions)' and he acids to the fharp of the dominant 'a frefh minor 
third. Theth thirds added, do not s it is true, form any propor- 
tion with the preceding references: the references, which them- 
felves ought to have, are often chauged; but that fignifies little .- 
Monf. Rameau gives povers to every thing for the bei. The 
proportion trves i to introduce the diflbnanc% and tIe errors 
of the proportion to make it felt 
'he illurious geometricJan, who las deigned tO make th 
xvorld acquainted with Mo.ff. Rameau's fyftem having fuppreffed 
all thelh vain calculations, I fhall folloxv his .exampl% or vill 
ß l'ather tranfcribe what he fays concerning thc diffonance; and 
l1on/ Rameau vill be indebted to me for having drawn this 
expl.anation fi'om the elements of mufic, rathcr than from his 
writings? 
It being ppofcd, that the effential elod of the ton% ac- 
cording to Mon/ Ramcau's fyftem, are' known x4z. in the tone 
el' u b the tonic't the domiuant tbl and the ihb-doYninant fa 
w. 
we muff alfo be acquainted, that this Gme tone of ut has the' 
two chords ut and tb[ common with the' tone of fol; and the two 
chbrds ut and fa, common with the tone of fa. Confequently 
this dlreion of the bat ut fol ma belon the tone of 
' , '  o tO Ut 0r 
'to that of fol; as the direaion of the bars fa ut or ut fa may 
appertain to the tone of ut, or to that of fa. 
In that care, vhen we pat from ut to fa, or to fol, in a [unda- 
mental,bars, we are Lill ignorant in what tone we are. It would 
be however ferviceable to know it, and be able, by rome me- 
thod, to diingnifia fle gcnerator from its fifths. 
We may gain this advantage by joining together the founds 
fol and fa, in the fame harmonY, i.e. by joinin to the harmony 
o fi re of the fifth fol, the other fifth fa, in this manner, fol 
fi, re, fa; this fa added, being the feventh o tol, forms a dit2 
tbnance; 'tis for that caufe, that the concord fol fi re fa is called 
diffonanr concord, or concord of the feventh. It tkrves to dif- 
tini the fifth fol from the generator ut, xvhlch always bears, 
without mixture or alteration, the perle& concord ut mi fol ut, 
given by nature heftelL (Vide Cocoo Consonance, 
Hov.) 
By this means we fee that when we pals from ut to 
we pals at the fame time from ut to fa, becaufe the fa becomes, 
by .this means, entirely determined, becaufe there is but this 
ton% to which the founds fol and fa belong at the ame 
thne. 
Let us now fee continues, Monf. D'Alembert, what we ould 
add to the harmony fa la ut, from the fifth fa, below the gene- 
rator, to diingufl this harmony from that of the ame generator. 
I.feems then, tat we flou[d add to i tle other fifth tbl, for

time to fo], and that'the tone may be thereby determined; buc 
this introdu&ion of fo[ in the concord of fa la ut would giw 
two feconds following each other fa bl, folla, that is to 
two ionances whol union would be too agreeable to the ear; 
an inconvenience which mu b avoided; for if, to diini 
the ton% we alter the harmony of this fifth f% we mu alter 
 little as poble. For this realon, inead of fol we will take 
ira fifth re, whiclx is the tbund neare to it, and we ihall havz 
for the b-dominant L thc concord fa la t re which we call 
concord of greater fixth or ficl added. 
We may tak notice here of the analogy which is obferved 
between the concord of tle dominan tbl, and that of the 
dominant fa. Thc dominant ol, by a6ending above the gene- 
rator, ha a concord entircly compold o thirds in atbending 
beyond 61 fol fi re f. 
Moreover s 
3 o D ! 
ut, we /hall find, in def'ccnding by ut towards rs, by thirds, 
ut la fa re, which contains the fame founds as the concord fa 
ut re gives to t'he fub-dorninang fa. 
We moreover fee, that the alteration of-the harmon T of the 
two fifths, confis only in the minor third re fa, o fa re, added 
on each fide' to he harmony of there two fifths. 
Tills explanation is fo much the more' ingenious, as it fhews 
at onc_ tile origin, fe, direrion of the cliftonanco, its aearef 
connettion with the tone, and tile method of determining reci'- 
procally the one by the other. The fault that I find in it bat 
an effential fault for making the whole glide, is tle u.fe of 
chord unknown to the tone, as the effential chord of the tone; 
and this, by a falfe analogy, ferving as a bars to Monf. Rameau's 
yfcein, deftroys it, by rendering itfelf erroneous. . 
I fpeak of that fifth below the' tOnic,.of that fub-dominane,. 
betveen which and the't6hi.c, thor6 canno be perceived the 
5rnalleft uni0n which can authorize the u-e oi; this rub-doral- 
haut, not only as an effential chord of the t0n% but eVen'in 
any lhnfe. In effe6t, what is there common between the ref0- 
ance5 the fhakinff of the unifon of ut, and the œound' of its 
i,fth below ? 'Tis by no means bocaufo the entire chord '; is 
fa, that its aliquots refound at the found of ut; but becauœe it is' 
a multiple of the chord ut; and there is no multiple of tt/ia" 
qme ut, which does not render a timilar phcenomenon. T-ak 
tlie felStuple ,. ii will /hake and i-efourtd in its parts 'as well as' the 
with the' tonic. 
I know that Monf. Rameau has pretended that at tile found 
of any..cho,-d another chord in i.ts twelfth below /hook w. ithout 
refound,ng.; but befide its Being a 4'c'ranehcenoinenon in the 
acoufti% -that a 10norous cha,'d wlfich/haes does not refound, 
it' is hbwever know%. that ' this pretended experience is an' e,'ror 
tli'at the tharp clord /hakes becaufe it divides itfelf, and that 
appears' not to refound, becaufe it f6rms in its parts only the' 
unifon ot7 the /harp, which is not eafily difinguifiaed. 
Let Monl;' Rameau then tell us that he takes the fiffla below,' 
,bocaufo he finds the fifth above; and that thi. pliying with fifths 
appca,'s to him convenient for tile eftabli/hm'ent of his irftem

Tke notice alfo, that if the counter-generation, which 
fuplofes could have a pace therein the concord of the 
rainant fa, /hould not, by' any'means, bear a major third, but. 
nilnor: becaufe the la Bemol is the true harmonic whicl is, 
affi. gned to it by' this change ut fa la , So that according to, 
this computation, the gamut of the major' mode ought natttraly 
,to have the minor fixth; but it has rdle major as fourth' fith, 
or as fifth 0/3 tile fecond note, Wherefore here is a œecond con- 
tradiction. 
La/tly, ake notice, that the fourth note given by tle feries of' 
ali.q_uots, from whence arifes the true natural diatonic, is by 
ß neans the oCtave of the pretended fub-domlnant, in the reference 
.of 4 to 3, but another fourth. note entirely different in the

To' reduce. a'11 thefg confonces to their Cmalle'

have the concord of the feventh, and on the other tkat of the 
fixth added; the onl tvo diffonant accords admitted in the fyf- 
tcm of the fundamen[al bari. 
it is not fucient to caufe the diffonance to be heard; it muff: 
be preffed; you then difguf[ the ear only to flatte it afterwards 
xnore agreeably. Here are two joint founds, on one fide the 
fifth and fixth, and the other the feventh and the oftave; as long 
as they will in this manter form the fecond, they will continue 
diffonant, but let the parts, whiclx make them to be heard, be 
dif[ant one degree; let the one afcend, or the other defcend diav 
tonically, and the fecond will on each fide become ,x third; thae 
is, one of the roof[ agreeable confonances. Wherefore, after fol 
fawillbefoundfol mi, or fala; and after re mi, mi ut, or re 
fa; and this is what is called preventing the diffonance. 
It remains to be determined, which of the two joined found 
fhould arcend or deftend, and which fhould continue as before; 
but the plav in determination Rares us in the face. Let the fifth 
or tl octave remain as principal chords, let the fixth afcend, and 
the feventh defcend, as acceffa:ry founds and diffonance. More- 
over, if, of the two joined founds, that which has the leaf[ com- 
fPcafS to make, fhould have the preferertce, the fa will again de- 
end on the mi after the fevenh, and the mi of the concord o

to.prevent the diffonance. 
et us now fee what courfe the fundamental found ought to 
take in relation to the movement affigned to the diffonance, 
Since oneof the two joined founds remains in ies place, it ought 
to form an nion in the following concord. The interval, whiclx 
the fundamental bafs ought to form t quitting the concord, 
ought then to be determined on thcl two condition: fL That 
the o&ave of the preceding fundamental found'may continue

the concord of fixth added. 2dly. Let the found, on which th 
diffonance is refolved, be one of the harmonies of that to which 
the fundamental bars paffes. Moreover, the bef[ movement of 
the bars big by intervals of the fifth, 'i it defcends from the 
fifth'in the f[rf[ caf, or if it arcends from the fifth in the fecond 
all the conditions will be ntirely fulfilld as it i! evidcn. t by 
thc infpci0n only of the. example.' 
Perle& Concord. Seventh. Sixth added. 
From thence is drawn a method Of knoving to whatever 
chox'd of the tone each of the two concords is moff fuitable. 
ß Vhieh are the two moff cffential chords in e.ch tone ? The 
tonic and dominant. How can the bat have its direrion by 
doit:ending from the fifth on tvo effentiaI chords of the tone 
tt muff: be by paffing from the dominant to the tonic, of which 
xhe dominant is the chord to which the concord of the leventh 
s moff fuitable. How can the bai by aftending from the fifth 
3ave its allregion on two effential chords of the tone ? 'Tis by 
Failing from the tonic to the dominant, and of which the tonic 
is the chord to which the concord of fixth added is moff apt. 
The reatb.n for wIfich fee in the example, where I have given 
tlielis to the fa of the concord which follows the latter, for the 
ß re being dominant tonic, ought to bear the major third. The 
bafs may have other dieions, but thole are the rnoft pe-t3; and 
the two principal cadences. (Vide 
If thch two diflbnances are compared wigh the fundamental 
found, we find, that that which delLends is a minor feventh, and 
that which rites, a minor fixth; from whence tve draw this new 
a-ule, that the major diffonances ough:t to arcend, and the minor 
delEcnd; for, in general, a major interval has let courlE to 
take ha arcending, ,and a minor in defcendinõ, and generally 
alfo in diatonic dh'tions, the finallet intervals are prefer- 
able. 
%Vhen the concord of the feventb bents a major third that 
hird 'orms with the feventh another cliftonanco, which is the 
falfe fifth, or by variation the triton. This third oppofite to 
the feventh, is hlfo called major diffonanc% and it is prefcribed 
to it to arcend, but that is in the quality of a tiniible not% and 
withoot the tkcond, that pretended diffonance would by no mean 
cifr, or would not be teated ,as

We 
D I 
vVc muff all'o take notice, that there two diffonances, viz. the 
major fixth and minor fcventh. tiff'e,' no more than a feml-tone, 
and would differ /'till lefs if the intervals wcre very exact. By 
the affiftance of this obthrvation we may draw from the principle 
of reaqonlng, an origin nearly approaching to both, as I will 
demonftrate. 
The harmonics vhich accompany auy found vhatever, are 
not bounden by thole vhich compofe the perfe concord. There 
are an infinity of others lefs fenfible in proportion as they become 
fiarper, and their references more cornpored; and theœe references 
are expreffed by the natural feries of aliquots, - T   g , 
&c. The fix firft terms of this feries give the founds which 
compofe the perle& concord and its redditives, the feventh being 
excluded; this feventh term, however, enters like them in the 
whole refonance of the generating found, tho' lef's fenfibly; but 
it does not enter as a confonance; it mute then as a diffonanee 
and this diffonance is given by nature. It remains now to fee its 
connexion with thole of which I have fpoken. 
This conne&i0n, moreover, is intermediary between eaeh and 
nearly approaching to both; for the reference of the major fixth 
$ 9 
is ; and that of the minor feventh . There two referencea 
48 45 
being reduced to the fame terms arc ands: 
80 80 
The reference of the allquot  conne&ed to thetimple by its 
4 7 
o&aves, is ; and this reference reduced to the fame term with 
. 
the preceding, is found intermediary between the two., in this 
336 yzo St 5 
manner ...... ; wherein we re% that this onnec"tion differs 
560 56 560 
from the major fixth only a , or nearly tw.o commas; anti' 
from the minor feventh .only a-, which is much lef 
han a comma. To make ufe of the fame founds in the diatonic 
genus and in different modes, it haa been neceffary to change 
them; but this change is not great enough to erafe the traces of 
their origin. 
ß I havfdemonPcrated, at the word Cadence, how the introduc- 
tion of there two principal diffonances, the fevcnth and the fixth 
addcd gives a method of uniting a continunc, of larmon¾ by 
Y z maing 
D I 
making it a'.'cend or dcfcend at will, by the interpofition of diœ- 
[nances. 
I make no mention here of the preparation of diffonances, lefs 
becaufe it has too many exceptions to tYrm fi-om it a genera! 
rule, thanbecaulE this is not its place. (Vide To 
]n regard to the dil])nances by foppotitiorl or lhl]enfion, ville alth 
tbol two word. 
Lafi:ly, I mention nothing of the dlminithed feventh, a pard- 
cular concord, which I fhall have occafion to cak of at the 
word Enharmonic. 
The' this method of conceiving the dilTonance gives a pretty 
clear idea of it, yet, as this idea is not drawn fro' the founda- 
tionof the harmony, I am very far from cn:leavouringto give it 
a greater praiiE titan it merits, nor have I even-given it more 
than its true worth; but they had till now reatbned fo ii1 on rlte 
diflbnance, that I o not ima ine m¾11/If to have proceeded 
worfe than others. Monf. Tartini is tle fi-fc and, tfil now, the 
only one who, has deduced a theory of ddTonarces from the true. 
principles of harmony. To avoicl ufeleœs repetitions, I convey' 
the reader to the word Syfrem, where I have made the expofition 
f his. I will not take upon myllf to judge if he has found, 
or not, that of nature; but I fhouId take notice, at leaft', that 
the principles of this author appear to hay% in their confequences 
that univerfalitv ,and connecCtion which is rarely found unlefs in 
thole which led to the truth. 
One obfervation more on this artlcle. Every commenfurable 
interval is really confonant: there are truly diffonant, only thole 
whole refcrnce's are irrational; for there are onl thole to which 
no common fundamental found can be a4Iigned. But the point 
being palTed wherein the laattlral harmonies are frill fenfible,, this 
confonance of commenfurable intervals is not admitted any more 
than the induion. In this care, the intervals form a great 
part of the harmonic fyfl:em, fince they are in the order of its 
natural generation, and are referred to the common fundamenta.1 
found; but they cannot be actmitred as contbnant by the ear, be- 
catvie it does not perceive them in the natural harmony of the 
corpo tbnoro. Betides, the more the interval is compelled; the 
more it is railTed. to the fharp of the fundamental found, which is 
proved by the reciprocal gcnera'tion of the fundamental found 
and thpe,'ior intervals. (ide the Svftem of Monl Tartini.) 
lMor½over when the dlftance of the fuudamentaf found, at the 
moR flOrll of the generato,', or generated interval, exceeds the 
extent of the muffeel or perceptible fyffem, whatever is beyond 
.that extent, being to be judged void ihch an interval has no 
tenfible foundation, aml ouglt to be reje&ed from prae"tice, o.r 
only admitte. d as a diffotam;. This is heirleer.the ftftem o.f

Monf. Rameau, or that of Tartini, or mhxe; but the dilates of 
na'ture, the remainder of which I do not pretend to explain. 
MAJOR DISSONANCE, Is that xvhich is prevented by 
arcending. This diffonance is only relative to the minor diffo- 
nance, for it forms a third or fixth major on the true fundamental 
fouud, and is no other thn the fenfible note in a concord do- 
minant, or a fixth added in its own. 
MINOR DISSONANCE, Is that which is prevented in de- 
fcending. This is always the diffonance properly fo called, i.e. 
the feventh of the true fundamental found. The major is atfo 
that which is formed by a fuperfluous interval; and the minor 
by a diminifhed interval. There different acceptations happen 
from the word diffonance being equivocal, and fignifying fome- 
times an interval, and at other thnes a timple found.

the aion at rome intererring moment, and which the aors and 
fpe&ators, the former fented, the latter fanding, have the pati- 
ence to fee and tilden to. 
DIVISIONS, By this  name were called the different methods 
of applying to the notes, the fyltables of the gamut, according 
to the different pofitions of the two remitones of the oave, 
and according to the different routes to come at them. As Aretin 
invented only fix of thel fyllabless and as there are feven notes 
'tO found in an oav% it mfifc be neceffary to repeat the name of 
Tome note. This was the reafon that they called always mi fa 
'or fa la, the two notes, between which on of the remitones was 
placed. There names determined at the fame time thole of the 
nearef notes, whether in arcending or defcending. Moreover,, 
as the two lmitones are fubje& to change their place in the 
modulation, and as there is in mufic a quantity of different me- 
tb0ds to apply the fix fame fyllables to thems there methods were 
called 
D I 
called divifions, becaufe the t211ile notes therein continually' 
chanzed their names. (Vide 
In'he left age the fyilable fi was added te the fix f}rft of the 
gamut of Aretin. By this means the feventh note of the fcale 
being found named, the divifions became uthleœs, and were aboo 
lifhed from file French mufic; but among all the other nations, 
where, according to the genius of the attiC, the muficians 
ways take their old track for the perfeXion of the art, they have 
not adopted b.e fi; and there is rome appearance, that in Italy, 
3n Spain in Germany and in England, the divifions wil, l ferve 
œom&ims for the inCOnvenience o : beginners. 
DO, A fyllable which the Italians tbfitute in the place of

triotire has led many perfons to undertake, and among other 
Monf. Sauveur, to chang? the names of the fyllables of our ga-

DODECC'HORD, Tiffs is the title eiven by Henri Glareart 
to a large book of his compofitio, in which, adding four near 
tones to the eght ufed in his thn% and which Rill remain in the 
Roman ecctefiaic canto's, he. thinks :lie has re-etablithed, in 
their prrrity, the twelve modes o'f Arifoxenes, wh% however, 
had thirtee; but this pretence has 'been refuted by J. B. Doni, 
on his Treaty On the 'Genera and Modes. 
DOMINANT, A dominant, or "fenfible concord, is that 
which is .ratqferl on the dominant 6f tone tone, and which an,. 
nounces the perle& cadence. Every major perfe concord be- 
comes dtrnlnant as loon as the 'minor fevenfh is added to it. 
t)OMINANT,.Is, of fie three effential notes of'the tone, 
that which is a fifth above the tonic. 'lhe tonic and the domi- 
aant determine the tone, they are each the fundamental of a par- 
ticular croncord; whereas i/he mediant, hich cor}fdtntes' the 
:node,'has no coreord itl 'it,. and only forms part of tlmt of 
the 'tonic. 
Monf. ameau generally gives -the name of dominant to 
-every mote which bears a concord of the feveth and diffin- 
ß ,uilhes which bears the ferrfiBle concord, by the name of domio 
ant tonic; but on a½courrt of the length of the .word, this ado 
dixion 'lia not been alopted 'by .artit}s and they continue to 
,call the 5th'of'the t0. nlc timply dominal!t, and .they do not call

DOMINANT, In church marie, is the note which is 
firuck, in'whatever oœ the tonic we may be. There are in 
church muiic a dominant and tonic, but no mcdiant. 
DORIC, Tile doric mode vas one t)f tile molt ancient 
the Greek marie, and it was the fiatreft arrd 1owe of thoth whicl 
have been fince called .authentic. 
The charaer of this mode was œeriou.q and flat, but of a 
temperate flatnefs, which rendered it proper for war, and religious 
thbjeCts. Pluton judges the lnajefy of the doric mode as very 
proper to preferve good morals; and 'tis for this redfort that he 
permits the ul of it in his republic. 
It was called doric beesafe it was in ufe among[r the people of 
that ns:he. The invention of this mode was attributed to 
Thamaris of Thrace, who having been fo unlucky as to defy 
the muls, and be conquered he was deprived by them of lfis eyes 
and ly re. . 
DOUBLE, Doubl% or redoubled intervals, are all thole which 
exceed the extent of the o&ave. In this f0nfe, the tenth is 
double of the third and the twelfth double of the fifth. Some 
give alfo the name of double intervals to thole which are corn- 
pored of two equal intervals, as the fatfe fifth which is corn- 
pored of two minor thirds. 
DOUBLE, They call doubl% the airs of a piece of marie 
fimple in itfelf, which are figured and doubled by the addition of 
many notes, which vary and adorn the canto. without disficrurinrr 
it. This is what the Irahans call variazioni. (Vide 
ATIONSo) 
There is this difference between the doubles and the flourifhe% 
that the one are at the choice of the muffclan, whictx he may 
make or quit at pleafare to re-take the timple. But the double 
i never left, for whea once it is begun s at mu be continued 
throughout the whole of the air.

D O 
re fa la ut, even tho' we fhould look upon it as varied fa la ut r,, 
cannot be followed. by the concord ut mifo! ut; I cannot be of 
hls opinion in that point. 
The proof which he gives of it, is that the diffonance ut in 
the firff concord cannot be prevented in the fecond fince it conti- 
nues in its place; but in this concord of the feventh, re fa la 
varied from this concord, fa la ut re, in the fixth added, it is not 
ut, but re that is the diffonance, which confequently fhould 
prevented by arcending on mi, as it really does in the following 
concord, in fuch a manner, that this couple is forced within the 
bars itfelf which from re could no b without an error, return to 
ut, but ought to arcend to mi, to prevent the diffonances. 
Monf. D'klembert then fhews that this concord, re fa la ut 
receded and followed by that of the tonic, cannot be authorized 
y the c]ouble emploi; nd this is Rill very true, iince that con- 
cord tho' c herc-d with a , is neither {reared as a concord oœ

riotic% that this diffonance is never prepared: Vrherefore, tho' in 
œuch a paffa e the double em Ioi is 'not brou ht in queffion tho'

the concord of the feventh is only there aptarentlv, and mpofiible to 
prevent in the rules, this doesnot hinder the laffage from being 
good and regular, as I have proved it to theoricians, and as I am 
going to prove it to artiffs, by an example of this paffage, which 
cannot affuedly be condennSd by any of them or juffified by 
any other fundamental bars than mine, 
Proof of the feventh varied from the fixth added.

! confers that this variation of thc fixth added, xvhlch conveys 
the diflbnances to the baœs, has been blamed by'Monf. Iameau; 
that author, taking for fundanental the concord of the feventh 
which refults from it, has chotn rather to make the fundamental - 
baœu deikend diatonically, and preyent a feventh by another 
v½llth thaa to explain this l:vcnth by a variation.

we mull obferve, as much as pofilbie, -to make them enter only 
one after the other, particularly the firil time, that their progref-

they cannot be heard together at leaPt that a portion of the one 
be heard with a portion of the other. But thefe laborious ta/k=

DOUBLE OCT-AVEr _An interval cornpored of two octaves, 
otherwise called fifteenth s and which the Greeks called dif-dia- 
pafon. 
The double octave is in computation doubled from the timple 
octave, and i the only interval which does not change its ham%

DOUBLE TRIPLE, _8. ancient name of the triple of mi- 
hums, or the meafure of three for two, which is ilck as three 
timed, and contains a minum for each time. This meafure is 
no longer in uti but in France, where it even begins to be abo- 
lifhed.

The dblcd has'three divifions, vhich we muff take notice 
viz. the half play the fweet and the very fveet. However 
.hearty there divifions may appear to be allied a wll-played band 
renders them' very difrin and fenfible. 
' DR:/MA'TIC,. Thi epithet is given to imitative mufic, proper' 
cto theatrical piece of tinging, as operas. It is alfo called ly.ric 
muc, (Vide IMITATION ) ' ' 
 ' DUET,. This' name is generally given to all kinds of mutlc 
-in: two' parts; but at preœcnt the fenfe is tellrained to two reciting 
parts, vocal or inftrumental; the œmpte accompaniments being 
cxcluded- which are looked upon as nothing. Wherefore we call 
duet an air for two voices; tho' there be a third part for the tho- 
rough. balsa. and others for the fymphony. In a word.to confri- 
tute'a due% two principal parts are neceffary between which the 
air mutt be' equally diftributed. 
The' rnles of the duet, and of two part mufic in general, 
are' the-mot. rigorous for the harmony; we therein refufe many 
paithges. man . movement% w. hich would be ermitted to a greater

formerly frill more fever% but all that has been' now laid aftde 
in tlielb lati:er'.times, where. all the worl/t let up for com- 
poters. ' 
We may view the uet in tw6 lights, vlz. timply as a two 
part air, fuch-s, for inllance, the firll terre of the llabat of 
Pergolefis the molt perfe0i. and affeetiug duet that has come 
from the pen of any muffclan; or as a par{of imitative and the- 
rrical, mutl'c, fuch :is the duets in the opera fceneso In each car% 
t. he duet is, of all kinds of muff% that which requires mow 
tall% choice, and the mofr difficult to treat.on, without going 
.from the unity of melody. I beg to be permitted to make rome. 
obfervations here on the dramatic duet whole particular dif 
ftculties are joined to thole which are common to all the duets. 
The author of the letter on the opera of Omphal% ha fen- 
Iibty rema,'ked that the duets are out of nature in imitative 
tie; for nothing i lefs natural than to fee two perfon fpeaking 
to each other for a certain tirne either to fay the fame thing o 
to contradiO without ev. lillening or anFwering each other; 
and tlao' this fuppotltioa mlgh be-halmitred in certain cafes, it 
could not frill be ufed in tragedy, where thi, indecenelr i neithe; 
fuitable to the dignity of the perfon who fpeak or to the edu, 
cation they are fuppofed to have. 
There ii nothing then but {he tranfporti of paffion which cam 
l,ad two heroic fak... t i.rup ae.h ,r to c both 
D 0  
, onee; and, even in filch a ca'e, it is very ridiculous that there 
pretended difcourfes fhould be prolonged fo as to make a compk:te 
piece on both titles. 
The firft method of preventing this abfilrdity is then, to 
place tile duets only in lively and touching fituatios, where th 
agitation of the fpeakers throws them into a kind of delirium, 
capable of making the fpeators and themfelves forget thole 
theatrical ornaments which fh'engthen the illufion in a cold tkene, 
and deftroylng it in the heat of their pafllons. The fecond 
thod is, to uth the duet as .much as poffible in dialogue. Thi 
dialogue ought not to be phrafed and divided into greater periods, 
ats that of the recitative, but formed of interrogatious, anœwers, 
ihort lively exclamations, which give oocafion to the melody to 
pals alternately and nimbly from one part to another, without 
ceafing to form a continuance, which may remain on the ear. 
 third attention is, not to take all the violent paffions indiffe. ro 
ently for fubje&s, but only thoœe which are ihœceptible of a 
fweet melody, and a little contraft fuitable to duets, to render its 
tune accented, and its harmony agreeable. Raze and paffion are 
too quick in their courfe. Nothing can be dfinguifhed; we 
hear only a confufed roar; and the duet has no effe. 'Moreo 
over, the perpetual return of injuries and inœults would be more 
fuitable to herdœmen than heroes; and this is exaly timilar to 
the rhodomontade of thole perfons vho prefer fear to danger. 
Much lefs flould xve make ufe of the loft accents, of chains, 
darts, flames, a flat and cold jargon, which pailion never knew, 
nd of which good mufic ands no more in need than good 
poetry. The inftant of a feparatlon, that wherein one of the 
ß two lovers goes to death, or into the arms of another, the fincere 
reformation of one faithleœs, the touching contention of a mother 
nd her fon, wifhing to die for each other: All thot moments 
of affliion, where one cannot fail of fhedding delicious tears; 
thole are the true fubjes to be treated in duo, with that fimpli- 
city of vords which is fuitable to' the language of the 
heart. 
All thole who have frequented lyric theatres know how much 
the word addio only elcites compaffion and ,emotion in the whol 
audience. But fo tbon as a piece of wit,'or vell-turned phra!, 
be ins to be perceptible, the charm in/tantly vanilhes and 
g

Herein are rome obfervations which are neceffary to the poet. 
In regard to the mufician, it is his duty to find an air fuitable 
to his fulgje, and diributed in thch a manner, that each of 
the fpeakers, taking his turn, the whole cornperi may forin 
'nalt one melody; which, without changing the fulqe, or at 
without altering the movement, may paih in is pl'ogrefs

' A much as this dialogue appears to be only the continuance 
of the fcene, what colles it into one duet only, is the unity of 
the defign, by which the mulician re-unites all its parts, according 
o the poet's intention. 
In regard to the burlefque duets, which are ufed in the inter- 
mediaries, and other comic operas, they are not generally for 
equal voices, but between the baœs and the treble. If they have 
not the pathos of the tragic duets, i, lieu of it they are fufceptible 
of a more friking varlety of more different accents, and more 
½xpreffive chara&ers. _All the gentility of coquetry, all the amufe- 
meat of the laughable charaers, all'the contra of the nonfenfe 
of one rex, and tile cunning of the other; lattly, all the acLeffar' 
ideas of which the fubje is fufceptible; all there may occur to 
throw a prettinets and an interciting harmony in there duets, the 
rules of which are in other refpe&s the fame as the preceding, 
in what regards the dialogue and unity. of melody. To find a 
comic.perfe duo to my liking, in all xts parts, I vill not omit 
the immortal author who has furnii'hed me with there two ex- 
amples, but will cite the rPc duet of the Serra Padrona:  Lo 
conoleo a quegl' occhietti, &c. &c." and boldly as a model of 
agreeable tinging, unity of melody, fimple harmony, pure and 
brilliant accent, dialogue, and tafte, in which nothing can fail, 
when it is well rendered, if the hearers who underftand it pay it 
that honour which it merits. 
DUPLICATION, A term in chm'ch mufic. 'The intonation 
by duplication is made by a kind of periclefts, by doubling the 
penultimate note of the word, which terminates the intonation, 
which has no place but when this penultimate is immediately 
bclow the Init. In that cal, the duplication ferves to mark it 
more fully, in tile manner of a fenfiNe note. 
DURATE, By this term is called every thing which difguf 
the ear by its cffc'dtr. There are voices rough and fliding, inftru- 
meats flaarp and frill rough, as well as compofitlons durat& 
The rough fiefs of the B fi'arp occafioned its formerly receiving 
the name of B durat& There are rough intervals in melody, 
thch as the diatonic prog,'ct of the three tones, wilethee in af- 
tending or falliig, and fuch in general are faire relations. There 
:,re in the harmony rough concords, ihch as the triton, 
perfluous tilth, and, in general, all tile major cliftonantes. Tim 
continucd rough'acrs is diluffing to the ca G and renden a plec,

CBOLE was in the mo ancient Greek mufic an alteration 
of the enharmonic genus, when a chord was accidentally railed 
five diefis's above its ordinary concord. 
EA. This word is figuratively ufed as a mufical term.. To 
hae an ear, is'to have a fenfiNe, clear nd true idea in hearing 
ufic; fo that, whether for intonation, or for meafure we'maF 
be difgued with the fmalle error, and pleafed xvi the buties 
of that art, when hearing them. He has a bad ear who is conti 
nually tinging fall% cannot diingui fie true intonation fr 
the fa-lfe, or who is not fenfible of the precifion in a meafure, and 
rikes it at an unequal or counter time. Wherefore the word ear 
is always taken for a nicety in.tho tnfation or judgment of that 
fendtire faculty. In this acceptation the word ear is never ufed 
hue with the fingular, and with tlxe pattilive article. "To have 
"an ear," &c. &c. &c. 
ECHO. A returned or reflexed found, hy a folid by, anti 
which by that means is repeated and renewed to the car. This 
word is derived frmn the Greek 0, a found. 
We call alfo by the name of ecn0, the place where the repev 
tition is heard. 
We difiinguifl the echos taken in this fenfe into two kinds 
viz. x, the timpie echo, which only repeats the voice once; 
dF the double, or multipl% which repeats the time founds 
twc% or more ibunds. 
In fimple echos there are rome tonics, that .is, which onlF 
repeat the mufical and fufiained found; and offsets l?11abi% whiclx 
repeat atih the wrds of the voice. ' 
We may draw a part fi'om multiple eclms tn form concordg 
and harmony with a tingle voice, by making between the volc 
and echo a kind of canon, the moaihre of which ihould be di- 
tched on the time whiclt paffcs betwixt the pnnouncd founds.

tqk on the organ that this method of playing is mo commonly 
nFed on account of the facility there is in forming ethos on

The Abb Broflhrd fays, that the word echo is rometimes ufed 
in the place of dolce, or pano, to denot% that the voie% or in- 
rumen% ould be fweerened as to form an ehho. Thi cuffo

ECHOMETRE. A kind of graduated fcale, or rule divided 
into feveral parts, which is ufed to meafurc the duration or length 
of founds, to determine their different powers, and even the refe- 
-rences .of their intervals. 
This word is derived fi-om the Greek Z0t, a found, and 
a meafure. I will not undertake the defcription of this machine 
becaufe no ufe will ever be made of it; and, as the be ech9metre 
is a fenfible ear, and long experience in mufic; thole who'Wi to 
know more of it, may confull the work of Monfieur Sauveu b in 
ferted in thole of the Academy of Sciences,  7 o . The' ill there 
find two fcales of this kind, one of Monfieur Sauveu b and the

' ECLYSE was, in the moff ancient Greek mufic, an airsration

xCurprlid, 'tis to hear a trifling piece of mufic, bald, confufed, with- 
out effeq and more proper to fl/un the ears than to delight them. 
On the contrary the eye wanders over the partitions of great ma- 
:Rers to difcover thole effe&s, ravifhing and rublime, which their 
mufic, when executed produces. It is, that a continued detail 
is ignorant of true geniu% that .it affords no amufements by 
quanti.ty of filly objects, but that it moves you by great effe&s, 
and the rength an d fimplicity of it unite alwayS. form its cha-

ELEGY. A kind of compofition for the flut% invented as

ELEVATION. The elevation of the hand or foot, i friking

raiid. Among the ancients it was the contrary. The e[evatiort

ELEVENTH. Replique, or oave of the fourth. This in- 
terval is called the eleventh, becaufe eleven rub aliatonics muf be

Monfieur Rameau wi/hed to give the name of eleventh to the 
concord which is generally called fourth; but as this denominax 
tion has not been tollowed, and as Monfieur Rameau himfell ha

ENDEMATIA was the air of a kind of dance peculiar to the 
inhabitants of Argos. 
ENHARMONIC, one of the three genera of the Greek 
œc often alfo called harmony by Arlfoxenes and his followers. 
This genus refulted from a particular divifior of the tetrachord 
accordiffg to which, the interval which is placed betwixt the li- 
chanos, or third chord, and the toefl% or fourth õeing of a tritons' 
or third major there continues to complete the tetrachord 
flat only a femi tone to divide into two intervals viz. from the 
hypator to the parhypaton and from the pa. rhypator to the 
chanos. We will explain under the ,word genus how the dlvi- 
lion was made. 
The enharmonlegenus was the fweeteR af the three in the 
opinion ofAriRides Q_dntili.an. It puffed as very ancient and the 
generality of author% attributed the invention of it to 
the Phrygian. But his tetrachotd or rather his diatefG'ron of 
ienus s contained only three chord which formed together' 
twouncompofed intervals flae firf'c of a fetal ton,, ,nd the' other. 
a third major; and from there two intervals alone, repeated from 
tetrachord to tetrachord, refulted at that time all the enharmonic 
genus. Twas not till after the time of Olympus, that tliey 
thought of inferting, in imitation of the other genera, a fourth 
chord between the two firl%, to form the divifion which I have. 
jut% mentioned. We may fee the conne&ions, accordinz to the 
œyffems of Ptolomy and Oriffoxenes, at the word diatonic. 
This genus fo furprifing, fo admired by the anclents and ac- 
cording to rome, the firl% difcovered of tile three, kept not its re- 
nown Ion. Its extrenie difficultr rendered it loon forfaken, in 
proportion as art gained combmat:ohs by Iofing its energy; and 
when the agility {vasa fubl%itute for the nicety, of the ear. Plu- 
tarch alfo finds great fault with the ,hUrlclans of his time, for 
having loft the fineft of the three genera, and daring to faY, that 
its intervals were not fenfible, as if every thing that efcaped.their- 
grofs fenres (adds that great philofopher) muff be out of nature. 
Ve have at relent a kind of enharmonic genus entirel - diffe- 
P Y 
rent from that of'the Greeks. It confifts as the two others,. 
a peculiar progrcfiqon of harmony which engenders in.the courl: 
of the parts of the enharmonic intervals by ufing it fucceffively, 
or, at the fame time, between two notes, Which are a tone from 
e,ach other, the B flat of th inferior, and the dieils of the fupe-. 
tier. But though, according to the rigor of the eonnec'lion, this. 
ctiefis and B flat ought to form.an. interval betwixt themfelves. 
(vide fqale, and fourth of.a.tone) This interval is found..void,. by. 
means of the temperament 'which, in the ettablifhed fy.'l%emi 
makes the fame tone ferye two purpoIs, which does not. prevent 
fuch a paffa,*e from producing, by the force of mo'dulation and/ 
harmon3r , ff part orSthe 'effeS2t,: ,vtfich {ve leek in the enhm, mo- 
nlc tranfitions: . . 
_As this genus is but little known, and as otr authors are con- 
tented o give rome notions of it too fuccinc'%, I think I muI[cx-.. 
plain it here a little more at length. 
We muff then obthrve, that the concord of. the feventh dimi- 
nified, is the only one on which we can praOke paffages truly'.. 
cnharmonic; and that by virtue of that fingular p. ropriety whiclt, 
it has of dividing the entire ouCtave into equal intervals. Let.. 
take in the tbur tbunds vhich comport this concord,. th.4t which. 
we wilh for fundament:al, and we thall.always equally .find that, 
the three other founds form on this a concox'd of 7th diminied,. 
Ioreover, the funtmcntal'tbund of tlxe concord of 7th dimi- 
nified is always a infible note; fo that, witut clmnging any. 
thing in this concord we may by a method of double,. or qua- 
d'ruple etnploy, make it thrve Ihccefiively. on four diffgrnt 
damcntals, viz. on tur. differat lcnfible ote, .. . -.. . 
' "It 
It follows thence, that this fame concord, without having 
hange, either in tle accompaniment oF the bas, may b½ar fou 
different name% and confecLuently be cyphed in four differen 
meths, viz. witha 7  under the name ofdiminied. fenth

It has been frequen. tl¾ attempted to make entirc-pIe,s in 
nharmonic genus, in imitation of the modulations in the diatonic 
genus. To give a kind of rule to f fundamental diro&ion of th 
genus it has' been divided into diatonic harmonic, which p. ro- 
ceeds by a fucceton of major femi toness- and in chromatic enr 
monic,'which proceeds by a fuceon of imi tones minor. 
The air inthe firR kind is dintonics' becaut its femi tones 
mjor, and it is enharmoni% becaufe two major femi tones toge- 
ther form a tone of enharmonic interval too Rrong.' To form hi 
kind of air, we tour make a bars which defends from fourth 
arcends from major third alternaiwfy. A part of the trio between 
the parc in the opera of Hippolltus is of this kind but it coul8 
tever be executed in the opera houfe at Paris, though Moeur 
Rameau aftares  that it has been perfom in other places h 
the conlent and dre of the muficians s nd had  furprYing 
The air of the fecund kind is chromatic, uf i t pms br 
minq Cemi tes. It is enharmonic, becaufe the to 
femi 'toqes minor form too weak a tone of an enhmoc in- 
terv'al'. .... " ' '

onfieur Alerobert, pag 9l, 9 93, and I66. ' 
In fpite of the exapl Oit{d and authorired by"Monfieur 
menus. I think it my duty tq hcquaint young artiRs' that the 
harmonic dintoni% and enharmic chromatic appear to me pro- 
per to.be reje&ed as genera,; ihR I cannot think that a piece 
mufic, modulated in this manner, v' 0 let the exeeutlon be th 
ruer perle&, can have the GnalleR mi. y reafons or% that 
the rough paffages of one idea to another , at a great diance a 
tb frequent therein, that it is not pobl (or the mind to folto 
there tranfitions with the 'fame rapidit a he mufie prefentg 
then; that the ear has not time to perceive th"f½c[ and com- 
bofed conne&ion of the modulations, or to under6a' the 
l*ntervals; that titere is no longer any adow of tte; oy 
in fuch fucceflions; that it is equally impelhie to retai''.that from 
which we go or to forefee that to which we a'e dired;; and 
that amidR all this we no longer have any idea where a'are. 
The enharmonic is no more than a paqge unexl)c&cd  the fur 
piiing impreffion of which is fro'reed Rrongly, and contlnue'a 
16n tme; a aage conlbquently which ougtt not to be re'

nion or apparent continuance and e effe& which refults fro

onfieur.Rameau when he fpent his time in felefs calculations, 
&ad paid a greater attention to the metaphyfic of his a, it is to 
 fappof at the natural fire of that arti had produced pro- 
igies the feed of which was in his geniu% but which his prepo- 
ons have always flM. 
I do not even think that fple enharmonic tranfitions can ever

' To'EXECUTE. To execute a piece of mutic, is to ting, and 
play all the parts which it contains, as welt vocal as inftrumental, 
in the unity which they ought to le; and to render it uch as 
'is pricked in the partition. As mufic is formed to be heard 
cannot judge well of it but by its execution. Such a partition ap- 
pears admirable to. the eye, which cannot be heard in its execution 
will,out difg; and another tnav perhaps apar plain and tim- 
ple to the eye, the execution of hieh delights by unexpeed el- 
ites. Undo-hand compofers, attentive to give fymmetry and 
play to all .their parts, appea,' generally the too5 ingenious people 
in the world, whil we judge of their works only th the ey

by uniting them in the common ti:nfe which ihey ought to form,

his eye, and that he would read with difficulty an unknown lan- 
guage, thougl written in the fame chara,51reru, and. cornpored of 
the tame word, wlieh he reads without heftration in his own. 
EXPRESSION. A quality, by which the mufician has a 
lively feeling and renders with energy all the ideas Which he 
fhotld utter, and all the'tkntimefits which he floqld exp. retk. 
There is one exprefilon in compofitlon, and anoth. er in execution  
and it is from thi:ir concurrent% that the moft mufical and rno 
tgreeable ff'ee"t refults. 
To give expreffio n to his works, the co.r;npofer fiould feize and 
compare all the connee'¾ions which may be found betwixt the 
ttrokes of his obje& and the lroduions of his art; he ought to 
know or feel the effe& of every chara&er, Ib that he may convey' 
that which he hits chofen to a degree fuitable to it: for as a good 
painter does not give an equil light to all his objehs an ingenious 
muffclan fhould neither give the fame energy to all his fentimerlts 
or the fame force to all his palnt}ngs; and fhould fix each part in. 
its convenient place, not fo much to give poyers to it alon% as to 
afford a greater effe to the wliole. 
- After having carefully iCought what he fhould fay he then feek-' 
*he metNod ho; and here begins the application of the precept 
in that art, which was a partialilar language, in the.which' the 
muffelan wifles to make himtill !nder. ttod. 
The melody, harmony. movement, and oholee of inftrument$ 
alad 'voices,' are tlie 'elements of mdfical language; and the melo- 
dy, by its immediate conne&ion with the grammatical and'orato-- 
ical ccount, is that which gives the oharaher to all the ?el}. 
Wherefore, it i always from the air that th principal exp'effioa 
fhould be dvawn as well in infrumental as vocal mufic. 
That then what we endearour to render by the melody i the 
tone, by which w expreli the fontiment, which we wifia to repre, 
fen b and we ought to be very cave. ful to imitate in. that the thea- 
trical declamation, which itfeli'is no more tha3 am imitation, but 
*o'follow the vo. ice of ,nature, whole accent ':ra wlthou½ aide&a- 
don, and without art. Wherefore.th muffclan mu firft tek a 
&ind of mlo. dy whicl.may fu,r.ni mufical intflcxiov, mof con- 
vertical; 
E x 
yenlent to the fenfe of the words, by always rubordinating the ex- 
preffion of the words to thole of the thought and even thole to the 
tiruation of the tbul of the fpeaker; for when we are deeply af- 
feOcd, every difeourfe which we hold takes a tint of the general 
fentiment which reigns in us, and we do not quarrel in regard to 
what we love, in the fame tone which agitates us in an indiff.erent 
matter. 
Our words are diff'erently accented according io' the different 
paillons that infpire them; rometimes fharp and vehement, romeO- 
times carelefs and loofe; again varied and impetuous, and then 
equal and tranquil in its infiexions. From thence the mufician 
draws the difference of the-modes in tinging which he ufes, and 
of the different places in the which he maintains his voice; eaufrog 
it to proceed in-the lower parts by finall intervals, to exprefs the 
languor of forrow and me}ancholly, drawing from it, in the higher 
partøs, fharp founds from pattlon or grief, and condu&ing it ra- 
pidly through all the intervals of his diapafon, in the agitation. of 
dellhit, or'the oppofifion of contrailed pailions. We muf parti- 
cularly obferve, that the charm of mufic does not confi only 
the i. mitation, but in an agree.able imitation, and that the decla- 
nation itfelf, .to eaufe fo great an effe& mufc be fobordlnate to 
the melody'; fo that we cannot paint a fentiment without Wing 
it that Charm which is infeparable from it, nor touch the hear 4 
unleti we pleafe the ear. And this alfo is very conformable to na- 
tur% which gives the tone of fenfiNe perfons an unknown affe&- 
ing and delightful intexion, which one without feeling can never 
inherit. Do not then attempt to ta_ke rhodomantade for expref- 
fion, or roughneff for energy; neither give a frightful pi&ure of 
the pations you wifh to exprefs; and,.in a word, do not, as in: 
the French Opera, where the tone of pattion is like to the cries 
from a oholie,' much more than the accents of love. 
The phytical plealure which refults from harmony, augrnent 
in its turn the moral plealure of the imitation, by uniting the 
a'Ereeable fenrations of the exprefiSve concords of melody, on the 
xca-lie ' principle as I have jut: mentioned. But harmony does 
more  it enforces the expreflion itfelf, b ivin a *,renter 'uRneft 
..... yg. g . j s 
and premfion to melodious intervals; t aremates ter chara&er, 
ahd fpeeifying .exaOly their place in the .order of modulation, it 
re.calls what, ' preceded , denotes what ought to follow, and thus' 
unite the phi, afeu in the air, a ideas are united in a difcourfe. 
Harmon. y, exa .m. ined in this manner, furnlfhes the compofer with 
variety n expreflion, which eftapes him when he feeks for ex- 
prefli6n in one'ha?.ony alone; for then, initend of animating the 
accent, he ttittes".t by his concord,; and all the intervals, con- 
ffiuhdeil in a continhed concourfe, offer nothing more to the ear 
fla.. a continuance 'o.f fundamental foundss whicl have nothing 
.a.fleecing or agreeable, and whole effe& has no' xmprefllon on our 
.mind. What then muf{ the harmonif{ to to form a concurrence 
with the eprefllon of the harmony, and give it a greater effe& 
He mut be careful to avoid to cover the principal found in the 
combirmrlon of concords; he muf{ rubordinate all his accompany- 
meats to the tinging part; he mut fharpen the energy by the 
curfence of the other parts; he mupt enforce the efT& of certairi 
.patEages by ftnfible concords; he mupt introduce others by fuppo- 
fition 6r fufpention, by counting them as nothing on the bars; he 
'muf{-give freedom to the Ptrong expreffions by major diffonances, 
'and mupt retain the minor .for fofter fentiments. One while he 
mut unite all his parts by continued and flowing founds; another 
.'wkile he will contraPt them in the air by fharp notes. One while 
Ee. ,;rill rike the ear by full concords and again enforce the ac- 
'cenE by he choice of a tingle interval. Or every fide .he will 
'render the finion of modulation prefent and fenfible,-and will make 
he bars and its harmony œerve to determine the fituation .of each 
afl'acr in 'the mode fo that we can never hear an interval, or 
roke n tinglag, wthout eling at the tkme time his cotroe&ions 
With.the whole. 
In regard to the rkyme, formerly fo powerful in giving force 
"variety, and tae, to poetic harmony; if our languages, lefs 
.cented and lefs profodie, have lopt the charm _which refulted from 
'them our muflc fubptitutes in its place, another more independaat 
iif the difcourfe in the equality of the meafure, nd in the dif- 
ferent combinations of its times, whether in the whole at a'tlm% 
or fep&rately in each part. The quantities ofanguage are almof 
Iot under thole of tile notes, and the muti% inptead of fpeaking 
with the. words, borrows, in rome refpe&, a peculiar language 
from the eafure. The force of the expreffion 'contiffs ih the 
pa'rt, in re-uniting thole two languages as much as pottible and 
in being careful, that if the meathre and rhyme fpeak not in the 
-lame rrthod, they may at leapt fpeak the fame things. 
The vivacity, which gives a gaiety to all our movements 
ought to give the fame al/'o to the meafure. Sorrow confines the 
foul fortens the movements and the fame languor is felt in the 
ifirs which it infpires; but when the grief is !ivel¾, or when. the 
fo;l i; agitated by miglxty combats the words are irregular; its 
ireeciofa is alternate with the flownels of .the fpondee, and. tile ra- 
'idlty of the p rrhic, arl is often retarded inptantly' as in the

One obfervatlon, which the cornpole,' ooght not to negle, is, 
that the more the harmony is removed the lefs lively the move- 
ment fhould be; fo that the mind ma.y have time to catch the 
courfi: of diffonances, and the quick union in the modulations; it 
is .only the la/'t tranfports of pailion which perinit an alliance be- 
txwxt the rapidity of the meafure and the roughhers of the con- 
cords. Then when the fenres feem to vanifil, and by dint eft agl- 
tation the a0or appears to have no more knowledge where he is, 
this energic diforde,: may be encreafed, fo as to force its entrance 
into the foul of the fpecqator, and even render him infenfible to 
every objetVt. 'But un}efs you a,'e fublime and great, you muft be 
cold and infipid. Throw your audience into an inihnfibility or 
be cautious not to fall into it yourfelf; for he wl,o lores his reao 
ibn is nothing more than a madman in the eyes of thole who pre- 
fi:rve it, and madmen intereft but little. 
Though the greateit force in expreffion is drawn from the com- 
bination of found% the quality of-their tone is not indifferent to 
caufe that effea. There are frong and fonorous voices, whole 
quality is good for a i}rong impreffion; others light and flexible 
good for things of execution; and rome fenfible and delicate, which. 
touch the heart by fweet and pathetic founds. In general the 
treble, and all fharp tones, are proper for exprefling tendernefs 
and fweetnefs; the bars and concordant for tranfports of pailion 
but the Italians have banifhed the bars from their tragedie% as a 
part whole notes are too rough for the heroic genus; and have fub- 
itituted in their places the tenor, whole note has the fame character 
vith a more agreeable eftcU. The3/ufe this fame bars more fuit- 
ably in the comic foe under parts; and generally for all profef- 
fionary parts. 
Inttrnments alfo have ¾ery different expreffions according to 
the found whether trong or'we.k whether the tone be fharp or

any founds in a greater o}fmaller quantity. Tile flute is tender the

which tler½ ca be drawn  lmre Varied 'and tniverfal exprefiion

of every orchefra, and fuffices to a great compofer to draw' fron 
it all the effes which a bad muffclan feeks in vain in the alliance 
of different inftruments. The compofer ought to be acquainted 
wi'th the handling the violin, to finger his airs, to difpofe his

FALSE FIFTH. A cliftonant interval, called.by the Greeks

femi tone; "that of the fifth being of two major lmi tones of 
minor on% and a femi tone major; and that of the falfe fifth onl 
of a major tone, a minor, and oftxvo femi tones major. lf on

flall have on one fide the faire fifth, as fi fa and on the other the 
witon, as fa fi; but thel two i,tervals equal in this fenfeb'are

ß Vherefore the caprice confis in the nature and affortment of 
ideas and the ideas in theh'uicknes in preihnting the. It fol-.

FIFTFL The fecond of the confonancas in the order of their 
generation. The fifth .is a perfe conœonancc. (Vide ½onbo 
nance.) Its found is connected ai fi'om two to three. It is corn- 
pored of four diatonic degrees coming to the fifth found, from 
whence it has its name of fifth. its interval is of three tones and 
a half, viz. two mhjor tones, a minor tone 'and a' major femi 
tone. 
The fifth may be changed in two ways, vlz. by dimlnifhing its 
interval a femi tone, and then it is called falfe fifth, andffhould be 
iiled diminithed fifth; .or by increaring the fame interval a femi 
tone, and then it is called fuperfluous fifth; fo that'the fuper- 
fluous fifth has four tones 'and the falib fifth three only as the 
triton, from which in our fyftem it only differs by the number 
of degrees. (Vide faire fiftl.) 
There are two concords which .bear the name' of fifth vlz. the 
concord of fifth and fixth which is alfo called greater fixth or 
t'ixth added and the concord of fuperfluous fifth. The firf of 
theYe two concords is confidered two was, i.e. as a change from 
the concord of feventh the third of the fundamental found being 
conveyed to flat ;'this is the concord of greater fixth. (Vide 
iixth.) Or as a dire concord, whole fundamental found is in 
lat and it is then the concord of fixth added. (Vide doubI* 
emploi.) . . . 
' The e'cond is alfo confidered txvowa¾s, tle one by fle lVrench 
the other by the Italians. In the French harlmony the fuperfluou 
fifth is the. dominant concord in the nilnor mode, below which we 
make the mediant be heard, which forms a therfluous fifth with 
the fenfible note. In the Italian harmony the thperfluous fifth is 
ufed only on the' tonic in the major mode, when, by chanc% the 
ira is diefis'd forming then major third on the mediant, and con- 
fetluently fuperfluous fifth on the tonic. The principle of thi 
concord, which appears to go out of the mode, ,nay be found in 
(he expofition ofMonfieur Tartini' fyttem. (Vide lyetern.) 
It is forbid in compofition to make two fifths togethers-by 
fitnilar movement'between the two parts; this would difgult the 
ar, by forming a double modulation. 
ß Monfieur Rameau preten4s to give a reafon for this rule by 
.defa.ult of union between the concords. ' He is deceived. In the 
firtt place then, two fifths may he formed, and the harmonic union 
preferred. Scco,dly, with this unio, the two fifths are Rill ill.

To FINGEt, Is w dirc the fingers in a convenient a 
gular m,r on any inffrument and chiefl E on the Organ or 
O.inRruments for the breaR, fuch as he violin and Vlolen- 
relic, the principal rule of fingering contiffs in the different 
tions of the left hand on the fieeve; it is by this means that the 
lame paWages may become eafy or difficult, according to the pofi- 
tions and chords, on the which we may take there puffages; it is, 
when a fymphoniff has attained to the art of palling nimbly with 
juffnet and precifion through all there'different pofitions, that we 
fay he is expert in the fieeve. {Vide Pofition.)' 
On the organ and harpfichord, the fingering is entirely diff'e- 
refit. There are two methods of playing or'there inRruments, 
viz. t.he accompaniment'and pieces. To play the pieces, we pay 
attention to the facility of the execution and to a pleafrog grace 
of the hand. As there are an excelfive number of poffible puffage% 
the greater part of which require a particular way of dire&lug the 
fingers; and flute, betides each country and each maker has his 
rule, there would be required on this part fuch details as this work 
would not perinit, and in which cuffore and convenience take 
place of rules, when once the hand is properly fixed. The gene- 
ral pre:epts which may be :iven are, firff to place both hands 
t e keys in fuch a mahner, as to have nothing incotvenient in the 
attitude, which obliges us enerally to exclude the thumb of the 
right'hand; becaufe the'tw thum13s placed on the keys, and prin- 
cipally on the white would give the arms a fituation conRrained: 
and by no means eracefuI We muff nifo take notice that thg 
elbows/hould be a little railed above the edge of the keys, fo that 
the hand may fall of itfelf as it were on thems which depends 
the height of our feat. Secondly, We tour hold the wriff nearly 
at the height of the keys, i, e on 'a level vith the elbow ' the 
gers muff be removed from the breadth of the keys which are to b 
touched, fo that they may be in resdiners to fall on different ones 
i_n their turn. Thirdly 3re muR. not fuccefilvely convey the fam 
nger on confecutive keys, but make.ufe of all the fingers of 
ach hand t .ldd to there obfervations the following rules, which 
boldly offer, fince I have them' froin Monfieur Dupli an excel- 
lent maffer on th harpfiChord, and who profeffes a perle& know- 
ledge of fingering. 
This perlE&ion confiRs in .general in a fort, enfy, and regular 
movement. The movement ot the fingers is taken from their root 
.that is, froin the joint which fixes them to the hand. 
ß The fingers mff be naturally benton. and each finger muff hav 
its proper movement, indPendantly 'from the reft. The fingers 
.muff tall on the keys and not rike them; and, n)oreover muff 
ttow one from the other in a fuccell%n. that is, we muff not leave 
me key before we have fixed on another. This chlgfiy regard 
the French methods of playin. 
Tc c/ntnue'a 'ak, we 'muf ufe ourtIve to' pat's te thffmb 
helow any finger whattbever, and to pail any other finger below 
fl>e thumb. This method is excellent, particularly when we meet 
wire dieils', or B's flat: then be careful that the thumb be fixed 
n the key which precedes the dieils, o'r B flat, or place.it imme- 
diately aœer: by this means you will ga? as nany fingers together 
s you xvil.have notes tO form. ' 
Avoid, as much as poffible, to touch a wlfite key witlx th 
thun:rb,. 'or'fifth finger, particularly in .very quick Paakes. 
, Th fame flake is often executed with the tyro hands, the fin-* 
ers of which, in that care, thcceed cacti other fucceflively. In 
ere aakes the hands pals one or the other, but we tour take no- 
ice, that the-fo'u.nd of the firR key, on which one. of there hands 
aftes, mu alfo be'united to the. precedent founds. as much. as if 
hey had' been touched l,y the fame hand. 
ß In the harmonious and united kind of mufic, it is neceffary to 
afe ourfetves to fubtitute one finger in the place of another, with- 
u-raifing the key. This method. gives facility in the execufionj 
d' prolongs the dfiravion of the foundvo . 
For the. accompaniment, the fingering of the left hand, ia the

be an union between them; that is to fay that rome one of 
founds of the p,.eceding concord flould be prolonged on the fot- 
lmving concord, and enter into its harmon. y. It is from this rule 
that the whole mechanifin of the fingering xs drawn. Since to pall 
regularly from one concord to another, rome finger mupt remain 
its place. It i evident, that there are ov, ly four method's of regu- 
lar fueceffion between two perfeaSt concords viz. the fundame:tal 
bars arcending or detendlng from third or fifth. 
When the bars proceeds by thirds, two fingers remain in their 
'place; in arcending, thole Which formed the third and ;fifth re- 
main the o&ave and third; whereas," that which formed the oe- 
-rave, dfcends on the fifth. In dfcending, the fingers which formed 
the o&ave and t!fird, remain to form the third and fifth; whilq: 
xhat which formed the fifth arcends on the o&ave. 
When the bari proceeds by fifth, one finger only remains in its 
place, an'd the two others take th.ir courfe; in afcending, it Ls the 
fifth which remains to form the o&ave, vhilpt the o.tave and third 
,defeend on the third and fifth; in defcendi:g, the o&ave remaina 
ß o form the fifth, whilpt'the third and fifth arcend on the o&ave 
and on the third. In all there fceceflim:s the two hands ha'e al- 
ways a contrary movement. ' 
By exercifing ourfelves on different parts of the keys, w ave 
ß foon- familiarized to the play of the fingers on each of there courfe, 
and the continuance of perle& concords can be no longer emba;- 
,rafting. 
In regard to the dillocmnces, we mupt firPt take notice, that every 
cornpleat diffonant accord mploys the four fingers, all of whicix 
may be arranged b thirls, or three b thirds, and the other'sned 
 Y - . . Y. . 
'to rome one of the firfiD fornung wth it an interval of fecond. In 
the firPt care, it is the loweft of all the fingers, i.e. the index 
which expr½lles the fundamental found of the concord; in the 
cond eafe it is the highePt of the two joined fingers. By this ob- 
fervation we eafily know the finger which forms the dillonanc½ 
lnd which confequently ought to delkend to preyeat it. . 
According to the cliff'ereCt Conlonant or diltbnant accords which 
follow t difl'bnant accord we murk' make one or two fingers 'de- 
œcend, or Ithree at the end of' a dillonant ccord; and the.perfe 
concord which prevents it is eafily found under the fingers. In a 
:ourœe ofdiffonant accords,when one finger alone detkends, aa in tlm 
interrupted cadence, it is always that which has formed the diffo.- 
lane; that'is to fay, the lower of the to joined, or the' higher 
of all, iffimy ar.e arranged by thirds. Sh{uld we make tvo. 
gets defcend: as m the œerfi:& cadence add to that whicl, I hava

of all thoqe are the two fingers which ought to defecnd.

on its key and make the three others defeend, 
The courfe of all there dirent fucceona, well fludied, flews 
you the play of the fiers in all ble phrafes; anti as it is fron 
rfe cadences that he mo common fucetfion of harmonic 
phrafes is drawn, it is alib in that that we mu exercife ourfclves 
mo: we all always find there the fingers direed and ccafitg 
alternately. If the two higher fingers defcend on a concord whcr 
the two loer remain in their place in the following concord tl 
two higher remain and the lower defcend in their turn; or at Ica, 
they ave the two farthe finers which Form the ihm play with 
the two middle. 
We may alfo find an harmonic fucc afcendlng by 
nances by fayour of the fixt added but this fucceon, le 
common han that I have fpoken of, is more dicult ta manag 
]els polonged and the concords feldom are filled with all their

FLEUIUI'IS. A kind of figured counterpoint, which is

FLOURISH.' A  kind of military air, generally ort and 
pleating, which is performed with trumpets, and imitated on otr 
in. Rruments. The fiourifi is generally with two trebles of trum- 
p:rs, accompanied by tyxbals, and wheu well executed has 
thig martial aud gay which is vety thitable to its ufe. Of all 
European troops the Germans have the her military inmments 
anti their aarches and flourifhes have an admirable effe. It is 
remarkable thlng that throhout the whole kingdom of Franc% 
there is not one trumpet which founds true; and the moR warlike 
nation in Europ% has the moR difeordant military inRmments, 
which is certainly attended with inconvenicies. During the la

FLOURISHES. This is fold in mufic offevel not which 
the mufician adds to his part in the executionI to ya an air often 
repeated to adorn  too timple paffag% or to giv a brhme to 
the volubility of his throat or fingers. Nothing can 'better e

makes of there ornaments. The vocal rench mufic is very cau- 
tious in regard t flouries 1 t even becomes more fo every day 
and if we except the celebrated ]eliote and Mademoilhlle l"el,

FOOT, 
FOOT: B meafure dœtime, or quantity,' dlftributeJ into 
rmre equal or unequa. l powers. Theri was in ancient mufic thi. 
difference between the tmes and feet, that the timCs were, as the 
rts or elements, indivifible, and the feet the firPc cornpored of 
.hef½ elements. The feet in their turn, were the elements of 
the metre or rhime. 
Wher were timpie feet, which could only be divided into rimes 
d others cornpored, which might be divided into other feer as 
½he thoriambic, whi. ch .might be refolved into a trochee and 
]ambi% the 1tonic into a ßpyrrhic and a fpondee. 
. There were rhimic feet, whoJ relative and determined quanti- 
Jes were proper to eRablifh reeabl½.conne&ions, as e ual, dou~.

œueh for inClance, as might be formed from French words, which, 
from fllort or long fyllables, have an infinity of others, without 
_cleric'trained poer; or which, long or fhort in grammar rules only, 
are not judged as fuch either by the car of the poet or by th 
]pra&.ic. of the people. 
FORCE. The quality of a found, called elco Cometimes Inten- 
ß fty, .which renders it more fendbit, and heard at a greater dipcance. 
The more or:lefs frequent vibrations of a .fonorous body, are 'what 
ender the found/harp or flat; its greater or lear diKance'from 
the line of the fftop, i$ what renders it ffrong or weak. When this 
difianceis too great, and the inffrument or voice is forced, (vide 
'lo force) the found becomes a noire, and ceafes to be agreeible. 
TO FORCtil THE VOICE, is to exceed its diapafon, high or 
ß low, or its extent 'by force of the breath; or fCreaming inecead of. 
tinging. Every forced voice lofts its jupcnefs; this even happens 
to initruments where the fiddle-Rick or the wind is forced and it 
is for this teafort that the French leldom ting true. 
FORLANE. The air of a dance of the fame name, .common 
in Venice, particularly amongit the Gondoliers. Its meafure is 
6_ . it is beaten galley, and the dance alfo is very lively. It is 
allcd I%rlane beeaufe it takes its origin in Frloul.whofe inhabi- 
tants are called Forlans. 
FORTE. This word is written in the parts to denote, that the 
1ound tour be forced with vehemence, but without raidrig it, lung 
in full voice, and much found be drawn from the infrument;'or 
Cometimes it is ufed to de:Kroy the 6fie& of the word dolc% ufed

'F'R 
FORTE PIANO; /in Italian fubttantfve c0rnpofed, ariel which 
the muffclans ought to frenchify, as the painters have chiar-fcur% 
by' adopting the idea which it expreffes. Theßforte piano is the art 
af fweetning and enforcing the founds in imitative melody, as 
do in thevords which it ought to imitate. Not only when 
fpeak with pailion, we do not alurays exprefs ourfelves m the fam 
tone, but we do not always fpeak even with the fame degree of 
force. VIufic, by imitating the variety of the accents and tones, 
ought alfo to imitate the intenfe or retails degrees of the worls 
and fpeak. one while dolce, another while forte, fumetimes a demi 
voice, and this is what the word forte piano generally expr½ffes. 
ß FOURTH. The third of the confonances i.n the order of their 
generation. The fourth is a perœe& confonance; its conne&ien 
from three to four: 'it is cornpuled of three diatonic degrees formeal 
by four founds, from whence it receives its name of tburth. 
inter.val is .of two tones and a half, viz.. a major tone a minor, 
and a major femi-tone. 
' The fourth may be changed two ways, i.e. by diminifhing its 
interval a fetal-tone, and then it is chlled diminifhed fourth; or 
faire fourthS; or by augmenting the fame interval a femi-ton,: 
it i then called tiaperfiuous fourth or triton, beesure its interval 
'has three full tones :" it has only two tones, that is, one ton% 
two femi tones in the diminithed fourth; but this lat interval 
banifhed from the harmony and only praL:-ifed in an air. 
Thereis a concord which has the nam of fourth, or fourthshalf, ft'. 
Some call' it concord of eleventh. It is that, ,.vher% under a 
cord of fevnth we fuppof.e a fift.h found in the bafs a..fifth 
the fundamental; for in that car% this fundamental formsß a fifth 
and its fcvanth has an eleventh' with the fulapofed found, (Vide 
Suppofition.) ß 
2nother concord is called fuperfluous fot{rth,. or triton. ß lt is 
:{'enfible concord, whole diffonanee. is conveyed'to the bars; for in 
that eafe t.hfenfible note forms a. triton on.that diffoilance. (Vid

can permit it. 
FREDON. An ancient word which fi_nifies a quick paffaffe 
'and generally diatonic of many notes on t'(e fame f3llabl. TTi 
is nearly what has been fince called trill with this difference, that 
'the trill has a longer duratio% and is writtenl whereas the Fredon 
is only. a flort addition in tare, or, as it was formerly called, a di- 
minution, which the finger makes on ehch note. 
FUGUE. 2k piece of mufic, wherein we treat, according to 
certain rules of harmon and modulation, an air called fubje, by 
. y 
making it pats fucceflively and alternately from one part to 
her.. 
There at/e the principal rules of the fugue, the one of which are 
]proper to it and the other common with the imitation. . 
I. The.fubje&procseds from the onic Io the dominanti or from 
. the dominant to the tonic, in arcending or falling, 
 II. Every fugue has its antwet in the part which immediatel/' 
trhllows that which has begun. 
lII. This anfwer ought to return the fubje& to the fourth 
.tfth, and by a timilar movement, as exa&ly as poflible proceeding; 
from the dominant to the toniC, when the thbje& is announced 
fr6m the tonic to the dominant, and vice verth. One part may 
.nifo retake the fame fnhje& in the o&av'e, or in the unifon of the 
-precedent; but in that cat it is a repetition rather than a tru 
..anfwer. 
. .IV. As the o&ave is divided into two unequal parts, the one oœ 
which comprehends fbur degrees in aicending from the tonic to the 
ß lotninarr, 'nd the otherOnly three. 'This obliges us to have at- 
tention to that difference in the expretion of the fubje&, and to 
.make fme change in.the anIhrer, not to quit the effential chords of 
the rhode. It i another thing when we propoi to change th 
tone;-in that car% the exa&nel of the antver itfelf, taken on 
another chord, produces alterations fuitable to this change. 
¾. The fugue mut be &figned in lhch a manner, as, that the 
antwet may enter before the end of the firf air, that we may' 
hear.each'of them in part at a time, that by this anticipation 
the fubje& may be united, as it were, to itfel!; and that the art: 
of the compofer may. be ewn i this colle&ion. It ia a joke to 
,give as a fugue, an mr, which only nafts from oe nart to ano~ 
ther, without any other difficulty t'han accompanyng it irn',ne- 
di:tely, This, t mof deteryes only tlt½ name of imitation. 
(Vide. lmtatiofi.) ' ' ticfides 
F U 
]eficles there rule which are œundamental: to fu½½eecl in this 
kind of compottlon, there are others, which: tho' only for taie 
zre not leœs effential.. The œugue% in gencraI render the mufic 
more noify than agreeable; for which reafo% they are more/uit- 
acle in choruffes than any where elfe. Moreover as their chief 
merit is to fix the ear always on the principal air or fubjes 
œnc% on that account we mke them pals inceffantly from part 
to part and from modulation to modulation: the compofer 1txould 
be particularly careful to render this air always very diftin& 
to hinder its being ftifled or confounde.d amongft the oher parts. 
There are two methods for this; one in the movement: whictx 
muff be continually contrafred: fo that: if the courfe of the fugue 
is precipitat% the other parts precede alfo by long notes; and 
the contrary if the fugue is dire&ed flatly .the accompaniment 
labour more: the other method is to feparate the hafmony left: 
the other parts approaching too near to that which tings the fub- 
je& fhould be confounded with it, and preven{ it being heard 
clearly, fo that what would be reckoned a fault every where elfe s 
. becomes a beauty here. 
fn Unity qf .elody. Here is the grand rule to be praifecl 
often by different methods. Me muff chufe the concords the in- 
tervals fo that a certain found and not an indifferent on% may 
caufe the principal effe viz. an unity of melody. We muff: 
rometimes ut into la  inftruments or voices of adifferent kind 
P P Y . 
fo that the part which fhould predominate may be moro 
difdugulfhed, viz. an unity of melody. Another obœervatior 
not lefs neceffary is, in the different unions of modulation$ which 
the force and progrefs of the fugue bring with them, to.take ear 
tat all theFe modulations be correfpondent at the fame time i, 
all their parts; to unite the whole in its progrefs by aa exa& con- 
formlty of tone r for fear that One part being in one ton% mud 
am. other in anotker the entire harmony fhould be in neither; 
lhould not prefent an)r timpie effeCct to the ear or timpie idea to 
the mind ,iz. an umt¾ of melody. In a word s in every fugue 
the confuflon of meldy and modulatioga is what at the tm½ 
t, im% ia mot to be feared and the moi difficult to be avoided 
and the preafure which thi kind of mufic producess being always 
middling: we may fay that a !ood fugue is the unrepaid chef- 
, d'euv/e of a gool h/$monif[. - 
There are alfo feveral other kinds of fugues as the perpetual 
fugue% called ganohs; the double fugue the counter fugue8 each 
of which may be fcen under its title: and which ferv½ more to 
extend the art of compofer$, than to pleafe the ear of an audi-, 
enceo 
Fugue is from the Latin fuga, Hight; becaufc the parts fcttng 
ff œo œuccelvely) tem to fly and putrue each other.

'The gamut has alfo been ciled an harmonic hand, becazfe Gui 
made ufe of the figure of a hand, on the fingers of which he 
ranged his notes to flaew the conne&ions of his hexachords with 
the five tetrachords of the Greeks. 
This hand has been in ul to teach to name the notes, tilt the 
invention of fi, which abolifles the diviGons amongft us, and 
confequently the harmonic hand which œerves to explain them. 
Gui Aretin having accordinz to the general opinion, added to 
the diagra TM of the Greeks a tet%achord in flarp, and a chord in 
Eat, or rather, according to Meibornius, having, by thefe addi- 
tions, eftablifhed this diagram in its ancient extent, tie called that 
fiat chord hypropoflambanomenos, and marked it by the F of 
the Greeks; and as this letter was found thus at the head of the 
œcat% by p. lacing. the flat founds above, according to the method 
of the ancients, it eaufed the name of gamut to be given to this 
fcale. 
This gamut then in tile whole of its extent, wa tompored of 
twenty chords or notes viz. of two oaves and a maior fixth. 
'There chords were reprefented by letters and fytlables. ' The let- 
ters invariably diinguifhed eacti a determined'chord of the real% 
as they do at prefent; but as there were then but fix tetters 
that there might be revert, and as it was neceffary to re-begin 
from oave to oave, they difinguifhed there oaves by the fi- 
gures of letters. The firf oave as marked with ca. pital let- 
ters, in this manner, Y. A. B. &c. The fecond in runrang-hand, 
g. a.b. And for the fupernumerary fixth they ufed double let- 
ters, gg. an. bb. &c. 
In regard to the fyllables, they only'reprefented, the names 
which were to be given to the notes in tinging. Moreover, as 
there were only fix names for feven notes k was through neceflity 
that one name was given to two different notes; which was ma- 
naged in fuch a manner, as.that there two notes, mi fa, or in, fa, 
thoutd fall on fetal-tones. Confequently as loon as a dieils or a 
]3 flat prefented itfelf which brought a new fetal-tone, the names 
were to be again changed which eaufed the fame name to be 
given to different notes and different names to the tiptoe note, 
according to the progrefs of the air: and there chanes of the 
name were called divifions. ß  
There di'vifions were then learned by the gamut. ./it the left 
of each degre% we 'law a letter which dnoted precilkly. the 
chord belonging to that degree. On the rizht. in the cafei'. we 
found the different names w]fich that note mih[ bear. in rifi2 or 
tlcfcending by B arp, or B flat, according 'o the p:ogreti.  
The dflIieulties of this method have caulhd dibrent eltanges 
to be made'in the gamut at iiveral times. This. plat xeprefents 
the gamut as i is now ufcd in Italy.

It is nearly the fame thing in Spain and Portugal, unlefs that 
the cotmnn of B fharp is rometimes found in the lat place, which 
here is the firif, or rome other difference of as little fignifica- 
tion. 
To rrmke ufe of this fcale, if we witl ting in natural, vre apply 
ut to r. of tile firff column, the length of which we arcend 
far as la, after which, pafling to the righ in tile column of B 
natur. al, we name fa; we arcend to la of the œame column and 
titan return in the precedent to mi, and fo in continuance. Or 
indeed we may begin by ut at the 1 of the fecoracl column, ancl 
When arrived at la, pals to mi io the firff column, and then repaf* 
in the other column to fa. By this method one of there tra-nfi- 
tions atwav forms a femi-tone. viz. 'la, fa; and the other, alwa¾ 
a tone, vi. !a mi. By B flat,'we may begin at the ut in c 
and torre the tranfition's in the flame manner, &c. ' 
In'deli:ending by B fharp, we quit the ut of the column in the 
xniddle, to pati to mi from that of the !l flmrp, or to fa from 
that bf B flat; then, de&ending as far as ut of that new ½o- 
lumn we go out by fa from the left t the right by mi frra 
right ro left. &c.

four firl'q ut re, mi ta changing thus the column every four 
notes, or every three, by a inethod timilar to that whi:h I have 
juff'explained unlefs in the place of la fa and la mi s we muff: 
move in fa ut and mi ut. 
The-German have no other gamut than the initial letters 
which exprefs the fixed founds in the other gamuts, and they even 
foIfa with thofe letters. 
The French gamut otherwife called gamut of fi prevents the 
embarraff'ment of all thefe tranfitions. It contiffs in a fimple fcale 
of fix degree. on two eolumns betides that of the letters,

in Metis ought never to pat two tones, nor diminifh below 
tone; fo that they had precilkly the œpace of a tone to vary the 
concord of the Lichanos, and this is the fecond rule. .The thircl 
was, that the interval from the parhypaton, or fecond chord 
fhould not exceed that of the fame parhypaton to the Lichanos 
As in general this concord might be divertitled three ways, thi 
conftituted three'principal genera, viz. the diatonic, chromatic 
and enharmonic. 
There two laf'c genera, or the two firf intervals, 'formed always 
together a fum let 'than the third interval, and were 'called ora 
that account, confined genera. 
In the diatonic, the modulation proceeded by a remic'tone,':[ 
tone, and another tone, fi, ut, re mi; and as we paffed througlx 
three confecutlve tones, from whence it received the name of 
atonic, the chromatic procee&d fuecefiively by two femitone 
and a hemi-diton or a minor third fi, ut Ut dieils mi. Thi 
modulation was placed in the miIdle between the diatonic ad 
harmonic, making, if I may be allowed the expreffion, different 
divifions be felt, juf as w}/en btween two principal colours were 
introduced feveralintermediate properties and from thence this 
called the enharmonic or colour'd genus. In the enharmonic  tl 
modulation proceeded by two fourths of a tone, by' dividing, ac 
cording to Arift0x. enes, the major fe'mitone into two' qual prts 
or a diton, or major fixth as fi, fi dieils enharmonle ut, and mi.s 
or, according to the Pythagoreans in dividing the major femi- 
to.ne into.two unequal intervals which formed one the minor fe- 
rretone, wz. our ordinary dieils, and the other the complement oœ 
this fame remitone minor to the remitone major; aid then th 
diton as befor% fi, fi ordinary d'iefis, ut, mi. In the firft cafe 
the two equal intervals of fi to ut ere both enharmonic, or the 
fourth of a tone; in the fecond cafe, there was no enlia, n/6/i 
but the paffage of fi dieils to ut', viz. the difference betweer th, 
minor anti majoi' femit0n% wllich is the diefis called fo by Pttla- 
õoras and the true enharmorfic interval given by nature. ' ' ' 
Therefore, as thi modulation, fays Monf. Burettes was ver 
much confined, runtting only flrough froall intervals almb im- 
idrceptlble, it Was called enhannonic, as one' would fay well 
joined, well coilvOcal, prob coagm. entata. 
Betides thel principal genera; 'there were others which refulte& 
all from the different pars of the tctrachord, or from methods' oœ' 
turning it differently from thole which I have menti0n&d. Arif- 
toxenes rubdivides tlie diatonic genus into fyntonic' hnd diatonic 
mollare, (vide Diatonic) azd the chromatic genus into' mollar% 
mollare hemiolian and tmic, (vide Ch,'omatic) whofh diffcrencea 
I4 G  
he gives as 1 have,/heurn under their articles. Ariffides Q.9;nrl- 
lian mentions many other peculiar enera, and he reckons up fix 
s very ancient, viz. the Lydian. Dorian, Phrygian, Ionian, Mi x- 
lydian, and Syntonolydian. There fix genera, which mu not 
be confounded with the tones or modes of the fame names, differ 
in their degrees as.well as in their concord; the one did not reach 
the oave the others reach'd and others pafs'd it, in fuch a man- 
ner as to partake, at the fame time, of the genus and the 
he detail of it may be feen in a book intitled the Greek 
fician. 
In general, the diatonic is divided in as many' kinds as can be 
gned to different intervals between the remitone and tone. 
The chromatic has as many kinds as may be agned to the in- 
ervals between the Imitone and the enharmonic dieils. 
In regard to the enharmonlc, it is not rubdivided. 
- Independantly of all these fubdivifions, there was alfo a common 
genus, in which were nfed only the able founds which belong to 
all the genera and a mixt genus, which partook of the chara&er 
of two or 0f all the three genera. oreover we mu take no- 
tlce, that in this colic&ion of genera, which was very re, there 
were not more than four chords made ufe of, but they were 
'tended or relaxed differently during the fame piece, which appears 
ather diqult'to praice. Iimane that perhaps one tetrachoM 
was tun'd in one genus, and aother in another but authors have 
not mae a clear explanation therein. 
We read in rioxenes, Book [. Part II. that until the time of 
lexander, the diatonic and chromatic were negle&ed by ancient 
muffclans; and that they. pra&ifed only the enharmonic genus, as 
the onl one worthy of their abilities ß but thik enus was enditel 
. Y . . ß g . . . 
abandoned m the nine of Plutarch, and the chromatic was allo lot- 
gotten before acrobius. 
The udy of the ancient writings, rather than the prgrefs of 
ourmufic has rendered us thee ideas 1o among their fucceffors. 
e have, as well as themfelves, th diatonic gertuss chromatic and 
enharmonic, but without any divifions; and we conrider there ge- 
nera under ideas very different from th0fe which the[ had. They 
had a many peculiar manner of condu&ing the mr on certain 
preffribed chords. For us, there are fo many manners of condu- 
Jng the entire body of hannony which force the parts to follow 
the intervals prefcribed bY there genera; fo that the genus belong 
ill more to the harmony which hngender ib than to the melody 
which canres its fenrations. 
. We mu obferve again, that in our mufic the genera are almo 
always mixt, that is, the diatonic enters very much into the chro- 
matic and eh of them is neceffarily intermingled with the eu 
harmonic. One entire piece of mufic in one only genus would 
le very difficult to be condu&ed, neither would it be fupportalfle; 
for in the.diatonic it would be impoffible to change the tone 
the chromatic, we fhould be forced to change the tone in each 
note; and in the enharmonic, there would be abfolutely no kind 
of union. 
All this is again derived from the rules of harmony, which fub- 
je& the fuccefon of concords to certain rules, incomparable with 
a continual fucceffion, enharmonlc or chromatic, and atfo from 
that of tile melody, which cannot extra& any kind of pleating air. 
It was different with the genera of the ancients, as the tetra- 
chords were equally complete: tho' differently divided in each of 
the three fyKems; if in ordinary melody, one genus had borroweel 
from another, other founds than-thole which were neeeffarily 
non between them, the tetrachord would have had more than four 
chords, and all the rules of their mufic would have been con- 
œounded. 
lonf. Bette, of Geneva, has made the diin&ion of a fourtin 
genus; which I have fpoken of in its article. (Vide Diacorn- 
naatic.)

tended demonfration. I now return to his ifem. 
The phyfical rinciple of the reafonance refents to us the foli- 
P ß P 
tary concords and elabliihes not the fueceffion. A regular fuc- 
ceffion is however neceffary. A dictionary of chofen words is not 
an harangue, nor a collection of good concords a piece of mufic. 
. fenfe is wanting; an union in the mufic as well as language 
receffar': Something of what precedes muf b tranfiuitted to wht 
follows, that the vhole may form a concinnity, and may be truly 
ß Moreover, the compofed fenfation, which refults from a perfeE 
:oncord, is refolved in the abfolute fenfation of each of the-founds 
v;hich com?ofe it; and in the compared fenfatlon of each of thet 
intervals which thefe fame founds form between themfelves, there 
is nothing beyond the fenfible in this concord; from whence it 
rollows, that it is only by the connection of the founds, and the 
analogy of the intervals, that the union in queiion can be efa- 
llifiaed: There lies the true and ol.y principle, whence flow all 
he laws oœ harmony nd modulation. [f thn, the .whole Of har 
mony was formed only by a fucceffion of prfeE major concords 
it would be fuficient to proceed to them b)r ntevals timilar to 
ho which cornpole fuch a concord; for then, rome found of the 
preceding concord being neceffaril¾ prolonged on the following, 
all the concords would be found fufficientl¾ united, and the 
mony would be n oe, at featS, in this lenin. 
But betides that fuch fucceœfions would exclude the whole me- 
Iod, by excluding the diatonic genus, which forms its bafs, they' 
would not reach the true aim of the art, fince mufic, being a 
½ourfe, ought, like it, to have its perlode, its phrafes, fufpentions, 
ops, and punuation of every kind; and as the uniformity of the 
laarmonlc courfes prefent ,nothing of thefe properties, the dla- 
onic courfe required the major and minor concords to be inter.. 
mixt, and we have felt the necefity of diffonances to mark the 
pa and phrafes. Moreover, the uulted fuccefi]on, oœ perle& 
major concord, neither gives the perfe minor concord, the dif- 
fonance, or any kind of phral, ad its punctuation appeas 
irelr erroneous. 
Monf. Rameau, infiing abfolutel¾, in his fytem, that all our 
Iaarmon¾ fhould be drawn rom nature, ha had recourfe, forthiz 
purpofe, to another experience of his own invention, which 
have fpoken o before, and which is changed lrom the firf. He 
ha pretended, that any found furnifiaed i i multiples a perfeX. 
minor concord in fiat, whole dominant or fifth. it was,,as it fur-. 
fiaed a majo in its aliquots of which it i the tonic or œun- 
fiamental. 
c]amental. -e has advanced, as a certain thlng that a fonorous 
laade tvo other flatter chords vibrate in their tot?lity, withot, 
however making them refound the one in its major twelfth, and 
the other in its feventeenth; and from this propofition,.joined to 
the precedenti he has deduced, very ingenioufly,. not only the in- 
troduStion of the minor mode, and diffonance m harmony, but 
the rules of the havmonlc phrai, and the whole of modulati(n, 
fxtch as we find at the words Concord, Accempaniment, Funda- 
mental Bars, Cadence, Diffonance, Modulation. 
But firft, the experience is falfe. It is known, that tuned 
chords, below the fundamental f6und, do not entirely flake witix 
this fundamental found, but that they are divided to render the 
unifon only, vhich coniquently has no harmonies below. It is 
alfo knowr/, that the propriety which the chords have of being di- 
vided, is not particular to thole which are tuned in the twelfth 
and feventeenth below the principal found, but that it is common 
to all its multiples, from whence it follows, that he intervals of 
twelfth and feventeenth, not being peculiar in their manner no- 
thing c.n be concluded from them in favour of the minor perfeCt 
concord which they reprefent. 
ß Though we fhould fuppofe the truth of this experience, this, 
Would be very far from removing the difficulties. If, as Monf. 
Ralneau pretends, the whole of harmony is derived from the re- 
ionance of a fonorous body, it does not then derive froin it the 
tingle vibrations of a fonorous body which does not refound. 
effe it is a {'crange theory to derive from what does not refound,. 
the principles of harmony; and it is frange in phyfic, o make a 
fonorous body vibrate and not refound, as if the iund ittlf was 
at all different from the air, thaken by the'e vibrations. Bcfides, 
the fonorous body does not only give, betides the principal fonnd, 
thofe founds which with it cornpole the perle& concord, but art 
infinity of other founds, formed by all the aliquots of the tJno- 
rous body. Why are the fi-fe founds confonant, and the other 
not, fince they are all equally given by nature ? ß 
Every found forms'a conc-ord truly perfed, fince it is formeel 
of all its harmonies, and by them it is that it becomcs a found. 
There harmonies, hovevei', are not heard, and we diftinguillx 
no moYe than a timpie fodnd, unlefs it be extremely firong; from 
whence it follows, that the only good harmony is the uniln, and 
that as we ditinguifh the confonances, the natural proportion 
being changed, the larmony has loft its purity. 
This alteration is formed two ways: firft, by giving a found 
to certain harmonics, and nt to others, we change the connec- 
'{ion of fore% which ought to reign amongft them all, to produce 
the fenration of a found, and the unity of nature is defttoyed. 
We produc% by doubling thel harmoni½s an effe timilar' to 
H i that 
o H A 
'that which wonId be. produced by x9ifling all the ret: for then 
we mull not doubt, but that, with the generating found, we miglt 
hear tho.Ce of the harmonres which we lhould have left; whereas, 
by leaving them all, they dellroy each other and concur toge- 
ther to produce and enforce the tingle fenration of the pri,,cipal 
found. This is the fame effe& which the full play of the organ 
produces; when reineying the regifters fucceffively, we leave with 
the principal he doublet and the fifth; for then that fifth and 
that third, which remained confounded, were tbparately and dill- 
agreeably diftinguJhed. 
Moreover, the harmonies which were made to found, have 
themilves other harmonies, which are not from the fundamental 
found: It is by there harmonies added, that that which produces 
them is Rill more roughly dillinguifhed; and thefe fame harmo- 
nies, which make the concord to be thus felt, enter n6t into their 
harmony. This is the realbn why the confonances which are 
moil: perle& naturally difpleat the ear, little qualified to under- 
fraud them, and I do not doubt but the oave ittlf would, as 
well as the veil, difpleafe, if the mixture of the voices of men and 
women had not given the curtom of it from its infant ttate. 
In the diff'onance it is ttill worfe, fince not only the harmonies 
of the found which give it, but that found ittklf does not enter 
ito the harmonious fytlem of the fundamentM tound; which 
caut's that the diff'onance is ahvays difkinguiflied in a difagreeable 
'manner amongft the other founds. 
Every touch of an organ in full play gives a perfe& con:orcl 
major tkird, which is not dillinguifhed from the fundamental 
œound, unlet we pay an extreme attention and draw the tones 
tkmcefliively; but there harmonic founds are not confounded with 
the principal, but by fayour of a loud harmony and an arrange- 
ment of regillers, l)y which the pipes which make the timtin- 
mental tburd telbund, cover with their force thol which give 
their harmonies. Moreover, we do not obtrve, neither can we, 
that continual proportion in a concert, fince, in c6njunetion with. 
the ch.ange of the harmony this greate force muff inllantly 
pali from one part to another, which is not praticabte and wou14 
entirely disfigure the melody. 
%'hen we pin 5, on the organ each toneli of the bars makes the 
perfeEt major co.cord tbund; but becaufe this bars ia not always. 
fundamental antl as' we often fnoclulate in perle& minor concord, 
this major perl%?.t concord is thldom that which the right hand 
tlrikes; fo that we hear th'-' minor third with the major the 
fifth with the triton the œu.pcrfluou tventh with the oe'tave 
and a thouland other cacophouies, with which our ear is little 
difgufied, bec:,u cuPcoin renders them convenient; but it could 
not be'prclhlzed'that it is the lh. me thing with an ear naturallit 
jutt, 
'H A 
uft, and which, for the firft time, we {hould put to she pmoœ 
of this harmony. 
Monf. Rameau pretends, that trebles of a certain fimplicity 
naturally luggert their bars, and that a man: who has an ear tru% 
and not exercifed, w11 naturally luggert it. This is a prep?fief- 
lion of a mufician proved erroneous by the whole of experience. 
Not onl he, who fhall never have heard bars or harmon , will 
Y . . .Y 
not find this harmony or bars of himfell, but they wxll dffpleaf½ 
him as loon as he hears them and he will prefer greatly the 
fimple unifon. 
When ;ve redeem, that of all the people of the earth Who all 
have a mufic and an air, the Europeans are the only ones wh 
have a harmony and concords, and who find this mixture agrac- 
able; when we refteEl, that the world hs continued fo many 
years, without a,mongft the cultivation of the beaux arts through- 
out mankind in general, any one's having known this harmony; 
that no animal, no bird, no being in nature produces any othe 
concord than the unifon, no other mufic'.than melody; that th 
eartern languages fo tbnorous, fo mufical; that the Creek air, 
fo delicate, fo fentlble, exercifed with fo much avc have neve 
guided thei voluptuous people, fond of our harmony that with- 
out it, their mufic had fuch prodigious efteEls, that with it ours 
is fo weak; that laftly, it it was reli:rved far the northern nations, 
whole rough and brutal organs are more touched with the eclat 
and noire of the voice, than with the fweeme of the accent 
and the melody of-the infleEtions, to make 'this va difcovery, 
and to give it /s a'foundation of all the rules in art: When ! 
tky, we pay attention to the whole of' this, it is very ditticIt not 
to'ihfpe& that all.our harmony is but a gothic and barbarous in- 
vention, which we fhould never have followed if we had been more 
infible of the true beauties o art, and of mufie truly natural. 
Monf. Rameau, however, pretends that harmony is the fource 
of the greateft beauties in mufic; but this opinion has been con- 
tradi&ed by fuels and reafon.By faEts becaufe all the great 
eff'e&s of mufic have ceafed and it has loft all its energy and

of mufic, being thole of nature, ar% and ought to be eelua!l'

By reafon, beeaufe harmony furnifhes ncimitation by which

HARi/ONIC 
HARMONIC HAND, Is the name which Aretin gave to 
the gamut which he invented, to hew the connexion of his 
hexachords, of.his fix letters and /ix fyllables, whh'the five 
.tra.chords '9.f the Greeks. ' He reprefented this gamut by the 
gure of a left-hand, on the finirers of 4hich were marked all 
fdunds of the amut, as well by the correfpondent letters as b 
the fyllable which he had jotned to them, by parting, by the rule 
of divifmns, from one tetrachord or finger tb another, according 
to the place where the two remitones of the o&ave were pinted 
by the B fharp or B flat, that is, according as the tetrachords

(Vide Tail.) 
Before the invention of printing, the notes-had only black 
keads, for the greatet'c pmrœ of the notes bei.ng. fquare,. it would 
have been too long to make them white in wrmng them. In [he 
imprefit.on, the heads of the notes 'were madwhlte, that is,

'that agitated air ondulations pretty frequen/ may aff'ord a foun;

thods of renderinz founds on infrruments, viz. by the vibrations 
'of the chords byhofe of certain elaic bodies and by the cel- 
lcOlon of the aiiut up within the pipes. I have fpoken at the 
'ord Mufic 0f the ingention of there inruments. ' 
They are generally divided into chord iruments wln0 anff 
percuffion inruments. The chord inruments among the 
clents we very numeroug. The mo known are the following: 
'Lyra, Pfalterim Trigonium Sambuca, Cithara, Peis Maga, 
$arb[ton, Teudo, Epigonium Simmicium, Epandoron, &c. 11 
there inruments were touched with the fingers or with 
pleOrum a kind of bow. 
For ihelr principal wind inruments they had there callM 
tibia, fiula $uba cornu Iituus, &c. 
The inruments of percuffion were thoFe which they named 
Wympanum Cymbalum Crepitaculum, Tintennabulum Crota 
lum &c. But many of there did not vary their founds. 
We cannot here find articles for there inruments or for tho 
of the modern mufic, whole number is exceffive. The in'm- 
mental parta not being entered within the plan of my work, f

INTERCIDENCE. A term m clmrch-mufic, (Vide 
iaptofis.) 
INTER-CT A fpace of time which paWes between the 
end of the a& of an opera and the beginning 'of the following 
'a&; and,' during wBich, the repretkntation ii fufpemled, whil 
the ai0n is lppofed to continue eltwhere. The ordaeRra 
fillu 
t1i ths 'pace, in France, by the executlon of a fynhony, 
which has alfo the name of interlude. 
It does not appear, that the Greeks ever divided their drama's 
by a&s, and, confequently, had no interludes. 
-The reprefentation wadnot fufpended n their theatres from the 
beginning o the piece to the end. It was the Romans, who, 
little fruitten with the ipeacle, began, firft to divide it into man' 
parts, whole intervals offered a relaxation to the attention of the 
fpe&ators, and this curtom has been continued amongft us. 
Since the interlude is formed to fufpend the attention and 
the mind of the fpeator, the theatre fhould remain emp, ty., 
the intermedes with which it was formerly filled, formed an inter- 
ruption of very bad tare, which could not fail of injuring, by 
rendering the thread of the a&ion forgotten. However, Molitr 
him[elf'did not fee this timple truth, and the inter-ats of him 
laft piece were illled with intermedes. The French, whole fpec- 
tacles have more teafort than fire, and who do not love to 
'kept 10rig in filerice, have, of late, reduced the inter-a&s to the 
fimplicity which they ought to have; and it is to be dellred, fo 
the'perfeCtion of th.e. gheatre, that their example fhould be everll' 
where followed. 
The. Italians, w.hom. an exctuifite fentiment often guides rnor 
ß than reafon, have profcribed the dance of the dramatic aion. 
(Wide Opera.) But by a confequence which arifes from the too 
great duration that they would give the fpe&acle, they fill their 
'inter-s wiih ballets, which they banifh from the piece; and 
tho' they may avoid the abfurdity of a double imitation, they 
fall into that of the tranfpofition of the fcene; and leading the 
fpeator thus from obje& to obje&, make him forget the principal 
ain, lore the intererring parts, and, to give him the plealure of 
the eye, take from him that of the heart. They, however, begin 
to re.el the error Of this monftrous atremblage, and, after having 
' almoft already' banifhed the intermerles of inter-a&s, doubtlef$ they 
'will not befitate to abollfh the dances, and to l>referve it, as 
ß becoming, t.o make a feparate and brilliant fpe&acle at the end of 
the piece. ß 
But tho  the theatre remains empty in he inter-a, I do not fay 
that the muffc fhould be interrupted f6¾, in the opera, where 
makes a part of the exiftence of things th fenfe of hearing ought 
to have fuch'an union with that of the light, that whilft we fee 
the lituation of the fdene, we may hear the harmony, which we 
!nuft fuppofe infeparable; fo that its concurrence malt" n?t at 
length appear ftrange or new under the air of authors. 
The difficulty wlich is prefented on this fubje&, is to know 
wltat the muffclan ought to di&ate to the orcheftra when there 
paffes nothing more on the ttage. For if the fymphon¾ as well 
I N 
as dramatic mutle, is no more than a continual imltatlo;. what 
hould it fay when no one fpeaks. What t;hould it do whe. n 
there is no longer any kind of aLødon ? I anfwer to that, that 
theugh the theatre be empty, the foul of the audience is not fo: there 
muft have remained on them a firerig imprefion of what they have 
.ft feen and heard. 'Tis for the etcheltra to nouriih and fufiain 
this impreffion during the inter-aLøc, fo that the fpeLøcator rrray not 
xeach the conelution of the following a& with the time c01dnef$ 
as he began the piece; and that interet may be unid in his foul 
as are the events in the reprefented aion. By this means, the 
muffclan never ceafes to have an objeLøc of imitation, either in the 
.ritualion of the characters, or that of the fpeators. The one 
never hearing but the exprefiion of there fentiments which they 
feel go out from the etcheltra, are, as it were, identified with 
3vhat they hear, and their condition is ib much the more pleafan 
as there reigns in it a more perfe concord between what 
their fenres, and touches their heart. . - 
ß The ingenious mutician draws alfo from his orcheira another 
advantage, to give the reprefentation all the effe& that it can 
ß have, by leading gradually the fpeator, attentive to the mo 
favourable fituation of the foul, to the effe of the œcenes which 
he is about to fee in the approaching an. 
The duration of the inter-aLøc has no fixed meafur% but it is 
lappored more or lefs gre.at in proportion to the time which that 
rt of the aion reqmres which pail'es behind the theatre. 
owevet, that duration ought to have the bounds of fuppoli- 
sion, relatively to the hypothetic duration of the whole aion 
and there of reallity, r½Iative to the duration of the reprefeno 
tation, 
This is aot the plac for examining if the rule of the =4 
honrs has a foundation fufiicient and if it is nver permlttcd to 
break through it. 
But if we would give to the fuppofed duration of an inter- 
;/t, the boun drawn from the nature of things, I cannot 
that any others can be found than thole of th time during 
which no fendhie and regular change was made in nature, as there 
is none made apparently in the /ene during the inter-a&. 
lVIoreovers this time is,  its greatett extent, nearly twelve hourss 
which form the middle'duration of a day and night. This fpace 
being paffed, there is no more pofiibility. nor illufion in the du- 
ration of an inter-a&. 
In regard to the real duration, it ought to be, as I have faid 
proportioned, both to the duration of the reprefentation, and to 
the patti,! and relative duration of what paffe behind th fccnei. 
]Ut there,are other boud drawn from th general end, whiuh 
we propof.e, ¾i.: tle menlure of attention; for we ought to be 
¾cr' 
very cautioas not to make the inter-aft Cninae f0 fir as to let 
the fpe&ator fall into a delirium and draw near to finmbering. 
This menlure has not fuch a precifion in itfelf, but that the muff- 
clan, who has fire and genius of foul may, with the aid of his 
orchei'cra, extend it much farther than any other. I do not even 
doubt but there are methods of deceiving the fpeator by the 
œeEtive duration of the inter-a, by making him eReem it mo 
or left great s by the methods of int(r-fixing the charaers of the 
fymphony. But it is time to fini this article s which is alread

The diWmnce between iaal and extent, is, that e interval 
is confidered as undivided, and e extent as divided. In the in- 
teal we coner the two terms only: in the extent, we fupfe 
eir intermediarie: The extent forms a fem, but e terval 
ma be ancomf. 
To'tke td word in its R genes! fenfe,' it is evident th

we bound al, b that means, e number of intervals to thole 
which tfe foand may form beeen themfelve. , that b 
eombiniagxwo by two,all e found of any yRem fver, we 
all have all potfible intervals in the fame fyRem; on which 
will remain truc under the fame kiad 11 thole wch 
be foun'd ul. 
The 
The ancients divklecl the intervals ot their mufic in timpie or 
ncompofed intervals, which they called diallemss and in compcrfed 
intervals called fyllems. 
The intervals, fays Arilloxenes, a?e difireTent five ways; Firll 
In extent. _8 great interval differs thus from a fmaller. Se- 
condly. In refonance or concord. By this a confoant interval 
½liff'erirom a diffonant. Thirdly, In quantity, as a firnple in- 
terval differs from one cornpored. Fourthly, In genus. Thus the 
ß liatoni% chromatic, and enharmonic genera, differ in themreDes, 
lvifthlys In the nature of their conne&io% as the interlral, whole 
rate may be expreffed by numbers, differs from an irrational in- 
terval. Let us fpeak a few words on all there differences. 
I. The fmalleff of all the intervals according to Bacchius, s 
ß he enharmonic dieils. The greatell, to take it, at the fiat ex- 
tremity of the hypo-dorian mode, to the flaarp extremity of the 
/aypo-fnixo-lyddai% would be of three cornpleat o&aves ;- but as 
there is a fifth to be removed, or even a fixth, according to  
laffage of _sdralles, cited by Meihonius, the fourth remaina 
above the dis diapafon; that is s the eighteenth s as the greatell in- 
terval of the Greek diagram. 
II. The Greeks divided, as we do the intervals, into confonant 
and diffonant but their divifions vere not the fame'as ours 
{Vide (2onfonance.) They again rub-divided the confonant in- 
zervals into two klnds s without reckoning the unifon s wh{ch they 
called homophony, or a fimilarity of founds and whole interval 
is void. Th, c fiiqc kind was th antiphony, or oppofition of 
foundss which was made in the o&ave, and was properly no more 
than a replique of the fame found, but'however an' oppofition 
ß xorn flat-to :[harp. The fecond kind was a paraphonys or diœ- 
tinfion of founds, under which was comprehended every co,ro- 
mance except the oave an8 its repllques: _811 the intervals, 
fays Theoh s of Smyrna, which are neither diffonant nr in 
nifon. 
IlL When the Greeks/peak of their diallems, or timple inter- 
vals, we mull not take this term in its full rigour,. for the dieflu 
itfelf was not, accordingto them, exempt froin compofition; but 
ß ve 'mutt always conne Jr'with the genus tb which the interval. 
iu applied. For inllance, the remitone is an interval fimple in' 
the chromatic genus., and in the diatoni% comp. ofed in the enhkr- 
toonit. The tone s cornpored in the chromaucs and fimi?le in 
the diatonic; and the diton itfelf, or major.third, which is an 
interval cornpored in the diatonic, is uncompofed in the enhar- 
rnonic. Wherefore, what is a fyllem in one genus may be a 
dialtern in another, and fo reciprocally. 
IV. On the genera: Divide fucceflively the fame tetrachords, 
according to the' diatonic genus the chromati% arid enharmonic, 
yot 
,-ru will have three different concords, which compared toge- 
tlJer, initd' of three intervals, will produce nine, bedfides th 
combinations and comp6fiti9ns which can be made of them 
and the dierence of 11 theFe intervals whic will produce 
multitude of others. If you cornpar% .r insane% th 
interval of each t;trchord in the enharmonic, and flat chro- 
matic of Ariffoxenes, you will have, on one fMe, a fourth,' oe 
a c  w-e' on the other, a third, or , and the two arp

.chromati% al enbarmonic genus. 
Ioreover, fince calculations not lefs cornpored are neceffary 
nd even geometrical operations more dicult, to meathre the 
thirds and fourths of the tone of Ariffoxenes than to affign the 
'co{neions of Pythago-as k is w.ith reatbn that Nicomachus 
Boetius and many other.theoricians preferred the juff and har- 
moni connerions o 'their lnaffer to the divifion of the Arif- 
toxenian fyffem, which were uot more fimpl% and which gave no 
inteyval in the juffnefs of its origin.

'to th mufic of the Greeks cannot be equally fuitable to ours 
becaufe all 'thi' founds of our fyem concur in contbnancer, 
which could not b done in theirs but for the diatonic genus 
It follo hence, that Arioyens diinguied wih reafon the 
intervals into rational or irrational; 'fince, though they wre 
rational in the fycm of Pythagoras the greate part of the 
fonances was irrational in hi,.

vlz either enerallv; as the fpace or diRanee of rome one 
the're givefi lgund; *gr as that only of the difiances which may 
be marked; or laly as thot which are marked on different 
grees. According to the firfi fenfe, every numerical power, as 
the'comma, or filen b as.the dieils of Ari6oxenes may exptet an 
interval. The iheond fenfe is applied to the iutervals only 're- 
ceived in the tRm of Our mufic, the lea of which is the minor 
feml-tone, exprcffed on the fame degree by a dieils, or B flat, 
(Vide Semi-tone.) The third accWtation fuppotks tbme 
renee in pofition: that is, one or snore degrees between the vo 
foundl which form the interval. 'Tis.in this la aceeptatioi

There two al'o may tie reduced into one only, but all confonances 
,nay become difforant by accident. (Vide Diffonance.) 
?vloreover, every interval is fimp!e or redouhle& The timpie 
interval is that which is contained within the hounds of the oc- 
tave. Every interval which exceeds thi, extent is redoubled; 
that is cornpored of one or more o&aves and of the timpie in- 
terval whole replklue it is. 
The intervals which are timpie are again divided into dire& 
and varied. Take as a dire& any timpie interval foei.:er, 
complement in the octave is always varied from that, and reci- 
procally. 
There are only fix kinds of timpie intervals, three o'f which 
make complements of three others in the0u"'t;ive, and confequently 
their variations only. If you then take the fmallef'c intervals, 
you will have for dire&, the fecond, third, and fourth; for varied, 
the feventh, fixth, and fifth. Let the one be direct, the othera 
wi?l I)e varied, and fo reciprocally. ' " ' . . 
To find the name of any interval œoever, we mu only add 
the unity to' the number of the degrees which it contains. 
,Vherefore the interval of one degree will give thee fecond; of 
two, the third; Of three, the fourth; of feven, the 0Crave; 
nine, the tenth, &c. &c; But this is not fitflicient to.determine 
an interval; for under the fame name it may be-major or minor,. 
juxOc or falfe, diminithed or fuperfluous. ' 
The im.per?e& confonances, and the two halrural cliftonantes, 
may be major or minor, which, without changing thœdegree, 
makes, ifi the interval, the diff'erence of a fetal-tone. from 
minor interval, we take again a fetal-tone, this interval become& 
diminithed. If we augment a major interval a fernitoh% it 
comes fuperfluous. 
The perle& confonances are invariable'by thelr nature. When 
their' interval is what it oughi to be, they are called jue, 
we change this interval a fetal-tone, the confonance s called 
faire, and becomes.a diffonance; fuperfluou$, if the tmi-tone 
added; diminifled, if .it is cut off'. The name of faire œfth ia 
given improperly to the diminithed fifth: it is taking the kind, 
for the genus. 'The fuperfluous fifth i quite aa fall aa the 
minilh.d and even in many refp&$ more lb.

prbperly the juftnefs of the intervals, and, confequently, to

they form no jar, but fuch as are rather uncommon. ½Ianyothers do 
not jar for another reafon, fince, to lore the tone it mutt firR have 
been.found. To ting without a key, to bawl, force the voice 
too high or too low and to have more regard to the extent than 
to the juftaefs,. are methods aimoft lure tO l}oil 'the ear, and at 
the Gme time to jar. 
JARGON, Is, in generar, every emotion of the air which 
renders itfelf fenfible to the audible organs. But in muff% the 
word jargon is oppofed to found and is underflood of every fen- 
fation of the hearing, which is not fonorous and appreciable. 
We may thppofe, to explain the difference in regard to thi% 
between the jargon and found, that the.laft is appreciable only 
by the concourfe of .its harmonies, and the _iare:on is not œ% be- 
cCaU/oit !s dipfrived of it. But betides that t,isnethod of appre- 
n ,s ilScult to conceive, if the emotion of the found 
canfed by the found, makes the allquots of that chord vibrate 
with another, we cannot fee why the emotion of the air, casted 
by the jargon, fhaking that fame chord, fhouid not, at the fame 
time, /hake its aliquots. I do not know that any propriety of 
the. air has been made which can make it fufpeEted, {hat tile agi 
tanon which produces the found, and that which produces the 
prolonged jargo% Rqould not. be of tile fame aature; and that 
the aon and re-aqion of.the air and the fonorous body, or of 
the aii- and tile jarring body, thould be eaufed' by different laws 
in the effeuq of each. 
Might it n.St beonie&ured, that tile jargon is not of a diffe- 
rent nature from the tbund, that ittlf is ouly'tlle rum of a con- 
fuœed multitude of different founds, which are heaed at a ritual 
and render,. in fo,ne. fort, 'their ondulations mutually contrary, 
All elaffic bodi.e fi:em to be more fonorous in proportion as their 
matter 
I N 2x 
matter is more homogenous, as the degree: of cobetlon is more 
equal thr0ughou, aml as the body is nor, as it were, dlvldd 
into a multitude of froall mafis, which, having ditTerent lblidities 
retbund confequently in dierent tones. ,Vhy lhould not the 
jargon be from the tbund, fince it excites it ? For ever), jargin t 
makes the chords o{ a harplichord refound, not rome ones as does 
a tbund, but all together, becaut- there is not one which finds 
its unitbn, or its harmonies. Why lønould nor the jargon be 
œrom the found, tince by founds the jargon is made ? Touch, at 
the fame time, all the keys of an inftrument, and you will pro- 
duce a total fenlhtion, wich will be a jargon only. and whofb 
effeEt will be prolonged by the refonance of the chords, only as 
every other noire which would make the fame chords retbtind. 
Why thould not the jargon be from the found, fince a toa frrong 
found is veritably a jargon, as a voice wh!ch fcreams to its utmofi: 
height, or particularly as the found of a large bell, which we hear 
even in the clapper itthlf. For it is impofllble to appreciate it, 
unlefs when iflhing from the clapper, the found be fweetened by 
,, convenient diffance. 
But it may be tid, how happens this change of an exeefllve 
found into a jargon } It is becautk the violence of the vibration 
renders the retbnance of 1 great a number of aliquots feufible; 
becaufe the mixture of fo ma,y different founds tb,'ms then its 
ordinary cite&, and is no longer any thing more than 
Wherefore the aliquots which refound are not only the hlf, 
third, fourth, a.nd all tde confonances,'but the feventh parr the 
ninth, the one hundredth, and. frill- farther. All this forms an 
effecøc timilar.to that of all the keys of a harpfichord ffruck at 
the fame time, and by this means the found becomes a jargon. 
The name of jargon is given, in contempt, allh to a conlured 
and noify piece of mufic, wherein more Fracas is heard than har- 
mony, and more clamour than air. "This is only jargon."

Euclid diftinguilhes two lydian modes. The above, properly 
called fo, and another which he calls flat lydian, and which is the 
fame with the aeolian raod% at leaft in regard to its fundamental 
'(Vide Mo%.) ' 
ß The chara&er of the lydian mode was animated, rlking, 
œorrowful however pathetic, and proper for foftnefs, for which 
eafon, Plato banifhed it from his Republic. It is on this modh 
that Orpheus, it is laid,' attractted the very beaft% and with which 
Amphion. built the walls of Thebes. It was invented, the one

MADRIGAL, A piece of mutic xvcll f{udied and ingcnlous 
vhich was very much in faflion in Italy in the fixteenth age, 
=rid even at the beginning oœ the precedent. The madrigal. 
were generally compold for the voice in five or fix parts, all 
brced, on account of the fugues and defigns wkh which the(e 
pieces were tilted; but the organiris compolhd and executed altb 
the madrigals on the organ; and it is even pretended, that it w, 
on this inftrument that the madrigal was invented. This kind 
'counter-point, which was fub. jceccd io very rigorous laws, bore 
the name of magridaleRlue f{i/e. Many au*.hors, for haSng eft-

certain 
'ecrt/iifi difference: when this difference may be remove, thejr 
are major; minors, when it tony be added. 
Thel variab!e intervals are five in number, vlz. the fetal-tone 3 
the tone, the third, the fixth, and feventh. In regard to tim 
..ione and rossi-tOne, tlieii' difference frbm major to minor cannot 
be exprecd in notes, but in numbers Only. The major fetal- 
tone is the interval of a minor fecond, as from fi to ut or 
from mi to f% and its conne&ion is from fifteen to tixteeh. The 
major tone is the difference of the fourth and fiftl b and its con- 
necqlon is from eight to hine. 
The three other intervals, vi. the tillrd, the fixtl b and 
feventh, always differ' a femi-.tone froin major to minor, and there 
differences ma be noted. Wherefoie the mino' third has-one 
tone and a hal and tile major third two tones. ' 
Tilere ai'e fome other ik/al!er intervals; as the dlefis and 
comma, which may be diftinguifhed in lefs, minor middle, 
major, and maximi; but as thefe intervals cannot be expreffed. 
but in numbers, thcl diftinEtions are ufelefs in praet.ice.. 
Major is allb thid of a mode when the tierce of the tonic 
major; and then tile word mode often is only undeitood ' To

MARCH, A military air, which is. played by inftruments of 
war, and denotes the metre and cadence of the drum% which is 
properly the march. 
ß 'Chaddin thys, that in'Perfia, when they are dcfirons of build-

expeditious work, Chi.ch requires a quantity of hands they 
ibmhie together tile inhabitants of one quarter, that they may 
ß labour With tile tbu.nd of the inftruments; and that by.this 
means, the xvdrk may be tranfaaed with much greater zeal and 
.quicknefs than if the inftruments were not ulkd. 
The Marechal de Saxe has fhewn in his reverie% that the 
-effe& o15 the drums was not bounded by a vain aoil without 
ntility but that, according as the movement was more lively 
.or flower i they naturally tranliorted the tbldier to prefs or 
.flatken his pace; we may alfo 13ty, that the airs of the marches 
thould h.'tvc different cha.'a&crs according to-the occafion where m 
/Hey were 0fed and this is what /hey ougilt to have refle&ed 
on to a certain point,. when they we.'e dittinguifled and di- 
ß verfificd, one fbr the ait'½mbling togcther another for the march, 
another for the charge, &c. &c. But it would have antvered 
vefy well if' tltey had protired by this principle a much 
they lnlght have done. They hay% tilt now, confined them- 
It:Des to the ccnn. pofing of tunes wMch lnight make the metr8

airs of marclx½;s allb very often are dcticicnt in that particular.

denies it.with reai7on; and.one muff have never read the writings 
that denon, to fuain an opinion which they fo clearly refute. 
lie not only Coinpares the powers which the' notes had before 
him to thole which were given them in his time, and which he 
does not pretend to be the author of but he even fpea.ks of the 
.menlure, and fays that the moderns that is his contemporaries, 
nunc mbrot' -' .... ' ' ' '^" ' '' ~ ' 
multtm utuntur menfura, which evldently fuppofea 
that the .mealare, and, 'confequentl]r, the power of the notes 
were known and ufed before him. Thole who would wifh to 
enter a more extentive feorch where that part of mufic was in the 
time of that author, fhould confelt his manufcript treatire,' in- 
titled Speculum Mufica, which is in tile king of France's 
brary nnmero 7207, page =8o. 
The firft who gave the notes any rules of quantity, were more 
attentive.to tim powers, or relative durations of there notes, 
l;han to the mealere itfelf, or to tile chaeaer of the movement; 
t7.o that before the diftln&ion of the different meafures there 
were notes of, at leafir five different.powcrs viz. The maximhm 
the 1ongu% the breve, the tbmi-brev e, and mlnime, which may 
be tken at their articles. ¾Vhat there is of certain?y, is, that all 
t. hefe. d. ifferent po. wers are fonnd and even more m the manu- 
fcripts of Machaulr, without finding therein any fien of mealere. 
. In the end, the connexion in power of one-ofhofe notes to 
the other, depended on the time, the. prolatio% and mode. By 
tile mode was determined the connexion of the maximum witlx 
the Iongee, or of tile longue' with .the breve; that of the 1ongne 
with the brev% or of the bre'e vith tlmth[ni-breve; and by

ifferene which renders a mode authentic or plagal, at the plea- 
lure of the compolhr. This colic&ion of all the rules is called 
melop6ea. 
The melopcea is cornpored of th?ee parts, viz. the prife, lepfis 
Which teaches the mufician in what extent of the v0iee he ought 
to eablifix his dlapafon; the medley, mixis, aftcording to xvhc 
he unites or mixes properly the genera or the modes; and the 
ufe, chrefe, which is thb-divided ihto three other parts. The 
fir called euthia, dire&s the courl of the air the xvhich is 
either dire& from flat to arl* , or changed from arp to fiat 
or mixt, tliat is; compothd of each. The fecond c11ed agog, 
moves alternatively by disjoint degrees in alkinding, and conjoin 
in defcending, or the contrary; The ird called pettia, b 
which be diterns and picks out the founds to be r6je&ed thoe 
to be admitted and thole to be ufed mo frequently. 
Ariides fintilian 'divides th whole melopa into three 
kinds, which are conneed with as many modes, taking this la 
name in a new fenfe. The fir kind was the hypatoides calle 
t'B from the chord hypate,. the principal or mo bafsi becaufe 
the air, dire&ing only the flat founds was not at a diance from 
at chord, and this air was proper to the tragic mode, Th, 
tecond kind was the mefoYdes from mefe the chord of the mid- 
dle; becaufe the air reigned on the middling founds, and this 
fwered t0 the nomic mode, confe'crated to Apollo. The thir 
was called nereides, from nete, le la or highe chord: its air 
was extended only on the.arp tBands and conituted the di- 
thvrambic or batchic mode. Th. modes had others, WhiCh 
xfire thbordinate to them, and varied the melopa; tBch as th 
erotic 6r a'm6rous the comics. arid ncomiac defined to praiCes. 
All there modes being proper to ex6ite or calm certaih paffionsi 
liad great influence on th manners, and by a reference to this 
inttuence, be melopa was agaih divided into three genera, viz. 
the t,altic, or that which infi ired tender and affe&in. 'aons 
. . . P . P 
the Iorroxvful and thole capable of engagingthe heart, accordifig 
to the fenfe of the Greek word. Secondly , the dlaaltici or 
that which was Orolier to exprefs noble tkntiments, in exciting 
joy, courage, magnaniinity. 'l'hirdfy, the euchaffici wlfidh xvaa 
Bctwecn the other two, and which refiot'ed the foul to a irate 
tramlutlity. The {irff kind of melopa was coh½8nient for 
amorous poetry tbrrows, bctvailingi and other timilar exprcffions, 
The tEcond was titable tbr tragedies warlike ai?s, and heroic 
thbjeOs. The third to hyflms, prailEs, or inffruOions. 
'MELOS, Sweetnell of tinging.' It is difficult to diffingui 
in the reek authors' the tnl of the word meloa from that or' 
melody. Plat% in his Protagoras,.placea the.m½1os in fimpla 
lkourlh} and t&mt to undcrffund by it the tune of the word,

The roelos appears to be that by which the melody was rendered 
agreeable. This word is derived from lzLx, Honey. 
MESYS, The name of the fharpeff chord of the feeond tetra-

Whis mode is affecting, paffionate, fultable to the trre. ate 
movement% and, by that mean% to tragedy itfelf. Ariffoxenes 
allures us that Sappho was the inventreti of it; but Plutarch 
fay% that rome ancient tables attribute it to Pytoclldes. He 
nifo fays, that the Argians punJibed the firft that ufed it, and 
who had introduced in mufic the ufe of revert chords that is 
tonic on the feventh chord. 
MIXT, We call mixt or connexed modes, in church 
the airs whole extent exceeds their oav% and enters from one 
mode into another, partaking by this means from the authentic 
=ncl the plagal. This medley is compoted of equal madcs, as of 
the firff tone with the fccond; of the third with the fourth 
ia wor.3, of the plagal with its authentic, and reciprocally. 
IIOBILE, The two middle chords of each tetrachord wer:e 
caIled mobile chords in the Greek mufic, becauœe they accorded 
diflrent!y according to the genera, with the difference of the 
two extreme chords, which, never var)ing, were called t'tab[e 
chords. (Vide Tetrachord, Genus, Sound.) 
MODE, The regular dilofition of an air and its accompa- 
niment, in. relation to certain principal tbuad% on the which 
.piece of nt:fic is conftituted, and which are called the effential 
chords of the mode. 
The mode differs from the tone, in that the former denotes 
'only the chord, or place of tile fyffem which ought to œerve as a 
bale to the ai% and the mode determines the third. and modeties 
the whole fcale on this fundamental found. 
Our modes are not founded on any charaerifiic fent}ment 
like tlofe of the ancients, but only on Our harmonic fyf[em. 
The chords effential to the mode are three in number, and form 
togethe. r a perfeLt concord. girf the tonic, which is the fun- 
damental chord off the tone and mode. (Vide Tone and Tonic,) 
Secondly, the dominant in the fifth of the tonic. (Vide Domi- 
nant. ) Th;rdly the median G which confHtutes the mode pro-. 
perly and which is in the third of the fame tonic. 
s this third may be of ta, o kinds, there are two diff'erent 
modes. When th mediant forms a major third with the toni% 
the mode is major; it is minor whets. the third is minor. , 
The major mode is imlnediately engendered by the refonance 
of tile œonorous body, which renders the major third of the fuq- 
d.mental /bund; but the minor mode is not given by nature 
it is fouv, d only by analogy and variations. 'l'his is true in tlxe 
œyftem of Mon; '-!'artini, as well as in that of Monf. Rameau. 
This laft author in his different thcceffive works has explained 
that origin of the minor mode in differet n,etbods no one 9f 
which has contented his interpreter M. l)'Alemhert. For which 
xeafo b D'aklcmbert founds that fitme origin on another princiEle 
which 
vMch I cannot cllfplay better than by tranfcribing the very 
terms of that great geometricJan. ' In the air ut mi fol, which 
' conftitutes the major mode, the founds mi and fol are fuch, 
 that the principal tound ut makes them both tound but the 
 fecond found mi does not make fol tbund, which is only its 
 minor third. 
"Moreover, let us fuppofe, that in the place of this found 
 we place between ut and fol another x%und, which has, as well 
 as the ftlund ut, the property of making fol refound and which, 
 however, is different from ut; this found, which we feek for, 
 ought ro be fuch, as to have for major feventeenth the found 
 fol or one of the octaves of fol; confequently, the fought 
 found fhould be in the major feventeenth below fol, or whicht 
st is the fame thing, in the major third below the fame found 
s fol. Moreover  the found mi being in minor third below fol 
 and the major third .being a fetal-tone greater than the minor, 
 it, follows that the found we leek will be a femi-tone lower 
' than the mi and will confequently b.e mi B flat. This new 
 arrangement, ut, mi B flat, fol in which the founds t and 
"mi B flat, each mak. e fol refound without ut making mi B flat 
"refound is nor, in reality, as perfeCt as the firPc arrangement 
 ut, mi, fol; becaufe, in the ne, the two founds mi and fol 
"are each engendered by the principal found ut, whereas, in the 
' other the found mi 'flat is not engendered hy the found ut 
 but this arrangement ut mi B flat fol, is fo dictated by 
' ture, tho' lefs immediately than the firPc, and, in effeCt; ex- 
' perience proven that the ear is but little accommodated 
 it. 
' In the courfe ut, ml B flat, fol, ut it is evident, that th 
t third of ut to mi B flat is minor and fuch is the origiti':of the 
 genus or mde called minor.':

lo.t only each degree takes the nare fuitable to it, 'but'.each

.As all the n.at.u. ral ch'q,'ds of the oOave of ut give, in relatiom

If you give tl}e pc!q;:& concord major to œhe tonic, the domi-

the mode.' 
As this medley of major and minor concords introduces, into 
zhe minor mode, .a faltk relation between the fixth note and the 
œenfible, we fmrrethnes give,- to avoid thi fa,œe relation, a majo 
hlrd to the fourth note in tbending, or the minor third to the

i'ailing, as it was given by that uuthor and executed in tle fpi- 
'ritual concert the 3oth o' May, '75 . 
It is ol}e&ed to .the Sieur de Blinville, that his mode has 
neither concord, effcntial clxord or .cadence fui.table to it and 
xvhich difiinguifies thfliciently major or minor. e anfwers to 
this, that the diWerence of his mode'is lefs in harmony than.melody, 
and [el in the mode t.han even in the.modulation; .ttxt i't is 
guiflled in its heglnning from tke mjor mode by its minor third, 
aa{ia it end from the minor mode by its plagal cadence. To whiclt 
we anffwer .that a ofl,ulation w]lich is not exclufive is nc.t 
fucient to eablifll a mode, that i.ts own is inevi.table in the tvo 
other nodes, particularly in the minor; and, in egard to its 
plaga[ cadcuce, .that i.t has neceffarily a pla in the ame minor 
node eyery time that we pats fro m the concord of the tonic to 
*hat of :the dominan% as that was formerly praiId eyen on the 
finals in tlxe plagal modes and in the tone of the fourth. From 
whence it is concluded, that hi mixt mode is lefs a peculiar kind, 
han. a new denomina[ion with methods for interm-ixi and 
combining the major and minor modes as ancleng as harmony., 
pra&ifed in every age: and that appears fo try, lhat even in

'fixtl {o'his ti$ .for fear of determining'fi tonic in minor mod.e 
,by the firif, or a edi'ant in major mode by the fecond. 
leaves an equivodation in not filling his concord. 
But 5}ateve obje&ion may be made again the mlxt mode, 
whole name is more reje&ed than its peaice, this will'not hinder

This is the cleareft notion that can be drawn from the tones 
or modes of ancient muflc, whilff they were looked upon as dif- 
fering only from fharp to ilar, but they had iill'othe.r'differencs 
'vh;ch charaerized them more particularly in regard to the ex- 
prefllon. They were draxvn from the genus of poetry which wfis 
œet to mufic, froln the nature of the Jnftrument which fhould 
accompany it, from the rhyme and cadence therein 'obferved, 
5tom the form in which ertain airs were placed amongft certain 
people, and from whence are derived originally the names of the 
principal ,nodes, the doric, the ph.rygian lydiai. ionian, an,d

There were alœo other fo'ts of modes, Which might have been 
]etter called fly]es or genera of compofition. Such vere the 
tragic mode deffined for the theatre; the Nomiach mode confe 
crated to Apollo; theDirhyrambic to Bacchus, &.c.. (Vide StyI 
and lelopcea.) 
In our ancient mut% they called aIo modes, n reference t 
the meafure or the tirne, certain methods of fixing the relativd 
powers of all the notes hy  general gn: the mode was theft 
nearly vhat is now called mealhre; it was marked in the fam 
manner after the cleff by circle. s. aud demi-circles, punuated or 
without points, followed by.the cyphe 2 or 3 diff'erently cored 
bined, to which were added or lhbffituted in the conrl, different 
perpendicular lines, according to the mode hi number and in 
length; and ir is from this ancient c/om,' that the ufe of th6 
(,nd ( barr'd has remained to us.- (Vide Prolation.) 
There were, in this tenfe, two kinds of modes, he major}

[f we ?urfue the .progrefflon of 'ffths as far as the twelfth 
power, Whic h happens'at œ dieils, we /hall find, that thi's fi 
ceeds the ut, whole Uniœon it ought-tO make in the connexion 
of 5:344 and 524.288, a connexion which gives the comma 6œ 
Pythagoras. So that- by this Calc,ulation, the'diefis ought to ex- 
ceed the;at of three rhajor comma s; and by the other it exceed 
it otly by the.comma of. Pythagoras. ' ' ' 
' But the fame found mi which for,ns the fifth of la, muff: alfo 
ferve to form the major third of ut; the fahe fi dieœs which 
f..rms the. twelfth'fifth of the fam 'ut, muff: 'form the 
alfo; and lattly th. efe different'concords 'mutt concur to conRi- 
tute the gneval fyffem' svithout multiplying tlie chords. This' 
is what is 'eecuted by means of the modification. . 
'For this purpofe, rift:, we begin by Ut in the middle of. the 
leys, and_weaken the four firff filths in 'afcendlng, until that the' 
fourth mi forms a major third, abfolutely .jutt 'with the .firfl:. 
tbund ut, which we call the firff proof. 
S. eeondly, In continuing to ttme by Hfths as loon 9s we .are  
art, red on the diefis's, we enforce the fifths a'llttle, .thou.h the 
thirds may fuffer, and when we are arrived to the fol die-ils, we .. 
ß -ft. This tbl dieils ought to make, vith the ml, a juff. lnitjor 
th,rd, or at leaff tolerably fo; this is ' the tcond'proof. ' 
ThirdlY; We t'ke the ut again, and tune the' fifths in 
viz. fa, 1 B flat, &c. weak of confequence; then enforcing them. 
by degrees, that is, weakening tl,e lbunds till we coine to the re 
]3 flat wlxich, taken as ut die-ils, b, ught'to be found i'n concord. 
and form a fifth with thd fol dlefis: .at' which we 'had bcforu 
ß 1topt. This is the thir,! proof. The 
eIhe laf fifths will be found rather xrong, as well as the major 
thirds, which renders the major thirds of fl B flat, and mi B .fl'r, 
laeavy and rather rough. But this roughnefs qll be fupportable if 
the partition is well forzred; and betide% there thirds, by their 
fituatio% are lefs ufed than the œrft, and ough. t to exift only by' 
choice. 
ß Th organifPs and faRors look upon this modifieatlon.as the 
rno:pefe tlgt can be ufed. In effe&, the natural'tones en- 
joy, by this means, all the purity of harmony; and the tranfo 
pored tones, which form lefs frequent modulations, offer great 
affifance t6 the mufician when he is in want of marked expref- 
fions; for it is good to obferye, fays Monf. Rameau, that we 
receive differertl: impreffions from the intervals in' proportion to 
their different a. lteratiors, For infiance, the major third, which 
naturally excites a joy"in Us, impreffes on us even the ideas of 
fu'ry, when'.to'o ]rog; 'and the minor third which infpires us 
xvith tendernefs and fweetnef% canges'our fenrations into thof½ 
of forrow, when. to 9 weak. 
Ingeni'o, us' muficiap?, ' co.ntinue the fame author, know how' to 
make a good ufe '.of there different effes of the intervals, an.d 
by the'exlreflign which they draw fr9..m them, make the altera-. 
tion flourinn, hic.h might be condemned. 
But 'in his harmonic generation, this fame Monœ Ramea 
fpeaks quite'ano. ther ihlng." He 'ieproaches himfell for lzis 
condefccnfion for acquaI cullom, and d,eftroying all that he had 
before eftablifhed; h.e gives b, formula of eleven methods p?o- 
port'ionate between the two terms of the o&ave, on which for 
mula he infifts on the Whole fukt:eon of the chromatic fyftem 
being eftablilhed, ¾o' that this fyfem refnlting from the. telv e 
fetal-tones perfelly equal, it is of neceffity that all the intervals 
Which are 'for.meal fdin it? .tho.u. ld be erfe&ly equal bet/veea 
themfelves. 
For prattlee, fays he, take whatever key you pleafe; tune then 
its fifth juit, di'mnifh ' i a 've'ry tittle; proceed in this 'ma,ner 
f,'om' one fifth to'anothe,',' always atcnding, that is, from fharp

A.s to what remaln,% I cannot be prevented to remind my 
readers of what I have laid at the word confonance, on the cau 
of that plealure which the ear receives from confonances, drawn 
from the fimpllclty 6f the connerions. The connexion of 
modified fifth according to Monf. Ramcau's method is this 
'43 
V 8o + V 8r. This conne&ion, however, pleares the car. 
would know whether its fimplicity is the caut of 
MODULATION. This is properly the method of eaablififing 
and treating the mode; but this word, at preint, is more gene- 
rally taken for the art of condu&ing the harmony, and tl{e air 
fuccevely in feverat modes by a method agreeable to the ear 
and conformable to rules. 
It the mode is produced by harmony Gore thence alfo afire 
the laws of modulation. There laws may be timply conceived, 
but are difficult to be obfervefi. Herein ties their confient zules. 
To modulate well in a fame tone, we mu fir go through all 
its founds with a fine mufic, by rlingthe effential chords oftchef, 
and relng o them longer: that s to fay, that the fenflhtc con- 
gord and theconcord of the tonic, ought to be ewn therein 
frequently, but under different appearancs and by different 
courfes, to prevent the monotony. Secondly, To eabli Ca- 
dences and ops only on thel two concqrds, or, at mo, on that 
of the rub-dominant. Thirdly and laxly, never to alter any of 
the founds of the mode; for we cannot, without quitting. it, make 
a dlefis or a B fiat M heard, which does not belong to t, or re- 
move any one tliat does belong to it. 
But to pals from one tone to another, we mu confult the ana- 
logy, and pa attention to the conne&ion of the tonics, and to 
the quantity. of chords common to the two tones. 
Let us now depart from the major mode: whether we nfider 
lhe fifth of the tonic, as having with it the fimpte of all the 
conne&ions after that of the oaave or whether we conrider it 
as the fir& 3f the founds which enter in the reibnnance of this 
fame tonic, we all always find that this fifth which is the do- 
minant of the tone, is the chord on which we may eabli the 
mo analogous modulation to that of the principal tone. This 
dominant, which formed part of the perle& concord of the fir& 
tonic, forms alfo a part of its own, of vhlch it is the tunda- 
mental lbund. There is then an union between theih two con- 
cords. Moreover, this ame domlnant bearing, as well as the 
condord a perfe& major concord by the principle of refonance, 
tlel txo 'concords differ betweea themialves only by the 
nance, wlfich, pafilng from the tonic to the doninant is the fixth 
added; and from the dominant, repafilng to the tonic is the i- 
S f venth. 
5o  0 
venth. 'V[oreover, there two concords, thus dlftingulfhed hy the 
tlifi'onance which thits each, form, by the founds which coml)oi 
them, van'd in or(r precikly the oave or diatonic fcale whicl 
we call gamut, which determines the tone. 
This lhme gamut of the tonic forms, only chaneed by a diefi 
the gamut of tle tone of the dominant, x3hich thews the great 
analogy of there tvo tone, and gves the facility of pang from 
one o the other by mean of a tingle alteration. The tone of 
he dnmlnant is then the fiL which is prefcnted after that of the 
tcnc in the order of moclulations. The thme fimplicity of con; 
re'dion which we find between a tonic and its dominant, is altb 
fomd between the fame tonic and its rub-dominant; t3r the fifth/ 
which tle riomigrant forms in fiaar.with tiffs tonic, the fub-do- 
nfinant forms in flat; but this tkh-dominant is the filth of the 
tonic-only by a variation; it is direly fourth by placing thi 
tonic in fit,' as it ouglt to be, which eablies the gradation of 
the connerions: for in this lknt, the fourth, whole connexion is 
from three to four follows the fifth immediately, whol connec- 
tion is from two to three. If this thb-dominaat ds not enter, 
in the three manner, in the concord of the tonic,'in return, rite 
t-nlc enters into its concord. For ould ut mi fol be the con- 
cord of the tonic, that of the fuh-dominant will be fa la ut 
xx'herefore,'it is the ut which forms here the union, and the two 
other founds of this new concord are precilly the to other 
5uncl. o'te precedent. oreover, we muff not change moe 
lbun3s for this tone than for that of the dominant: there arc in' 
each all the throe chords of the principal tone, very nearly. (3ive 
a B flat to the intible note d, and all the notes of the tone 
ut will ferve to that of fa. The tone of the luh-d0'minant is 
then leli analogous to the principal tone than that of the domi- 
Ve oght alfo to take notice, that after having ufed tliis 
modulation to pat from a principal tone ut tothat o[ its dominant 
'-, we are obligecl to ut the cond to return to the principal 
lbund; for if 1o is dominant of the tone of ur ut is fub-doni- 
nant to th tone ef tbl; where[br% one of there modulations 
not lefs necelhry than the other. 
The third tbund, which enters in the concord of the tonic h 
that of its third or medianr and is altb the fimple of the con- 
234 
notions after the two precedent ß

Here then i a new mo,lulati,m, which is prefented antl 
much more analogous as two o[ the founds of the principal toltec 
enter allb into the minor concord o[' its mcdaant; for the

But what removes this modulation to a little dlitance, is file 
quantity of found which murk be cha,ged, even for the minor 
n,ode, which is molt tklitab'le to this mi. ! tave given he'fore the 
fo,'n,ula for there two modes; therefore, applying this formula, 
to the minor mode nfi, we find, in reality, only the fourth fount 
fa changed by  dieils in defcending; but in tiring, we find 
others nifo, :iz. the principal tonic tit, and its fecond note 
which'becomes here a fenfible note: it is certain, that the altera- 
tion-of fo many founds, and particidarly of the t.nic,.dicac 
the mode, and Weakens the anrilogy. 
If we vary the third as.we have t.le fifth, and take .that 
below the tonic on the fi.xth note la, which we ought alt'o 
Call œub-mediant, or mediant below, we thall form on this ta 
modulation more analogous to the principal tovie thaaa was t'hat.of 
mi; for the perfecq concord of this fub-medlant'being la tit 
we find therein, as in that of the mediant two of the .found 
which enter into the concord of the tonic, viz. ut and ixfi; anti 
moreo;-er, the fcale of this new tone being compofecl at leait im 
dekending, of tie f.,tne founds as that of the prini:ipal xonc-3 
and havifi-g only two founds changed in af'cending, i.e. one lefs 
than the tka!c or' the mediant; it follows thence, that the mod.tt- 
lation of the fixth note is preœerabte to that of this median% in-' 
afmuch as the principal tonic forths therein one of-the effential 
Chords of th mode, which is more fuitable for conneEting tke 
idea of the tnodulation. The mi may follow afterwards. 
Here then are four chords, mifa folla, on each of whiclx w 
may modulate, going out of the major tone of at. Let tl,e re 
and fi t'emain the two harmtmies of the dominant. This lai 
as a fenfible note, cannot become t:otfic by an)' good modulatlon 
at leaff immediately. This woald be applwng roughly to tim 
tame tbund, ideas (oo much oppotEd, and gfving it a'n ha,'mony 
too diffant ft. om the principal. For the tEond'fiote re, w.e may' 
alib by fayour of the coniChaut direction of the futdamental 
bars, modulate therein in minor third, provided that we do not 
remain therein qore than an initant, t¾ that we may not ha'e 
time to fot'get the modulation of the ut, which i.tfelf is changed 
othersvilE it would be necettkry, inffead of returning immediately 
in ut, to pat hy other intermediate tones, where it would be 
dangerous to be led into an ½r,'or. 
By following the i;.une analogies, we fiall modulate in the fol- 
lowlug order to go out of a minot. tote: the mediant iirft, then 
the dominant, the ihb-dotnitatt, and the thb-mediant, or tixtlt 
note. The mode of each of there aceedify tones Ls.determiaed

ks mediant ut in mawr mode, becaufe the dominant mi of the 
øne, d-ran whence we go out, forms a major third 0n tlie tonic 
 that wherein e enter, &c. ' 
Tliefe rules, confined in a general formula, are, that the modes 
f the dominant, and the iub-dominant, are timilar to that of the 
onic, and that the mediant and fixth note bear the oppofed mode. 
e' mu take notice, however, that in virtue of the right we 
have o.pafs from m4or to minor, and reziprocally, in a fame 
ßone, we may nifo change tSe order of the mode from one tone to 
ghe' other: but in tllus vetoeying from the natm'al modulation, 
we mu be attentive to the return, for this is a general rule, 
'hich every piec e of mufic ought to finifl in the tone by which 
i Began.. 
I [ve oIIeed  two ort examples, all the tones ;n whlclx 
w.e m&y immediately pals: the fi, by going from the majo?

ut i.t is not fufficient to know the courls which we ought to 
foUw; we mu alto know the method of entering on them. 
ere is !he luminary of the precepts which may be given in re- 
gavd o this. In melody, we mu, to exprefs the modulation we 
have.chotn, only make.the alterations be hoarcl, which it pro- 
duces in.he;fo.unds of. the tone from whence we go out, to render 
them proper to the tone whereLa we enter. 
Are we. in ut major' ? We have only to tound a fa dieds to 
exp'et tle tone of the dominant, or a fi B flat to fpeclfy the tone 
of. the tb-dominant. Then pal through the effential chords of 
the tone wherein you enter: If it is well cholla, your modultiotx 
11 always be good and regular. In tte lartnony tiere is a 
little more difficulty; for as the chane of the tonc mu be made 
at the fame time in all the parts we ought to be careful in th 
harmony and ai% to avoid following two different modulation 
at the Famc time. HuFfhens has ver well remarked that

ciple: in effe we cannot form in any manner fcvcral juff fifrh

is called Latin mufic.

has not œufficient gravity for the ut to which it is allotted.

MOVEMENT A deg,'c½ of qulcknclk or flownel, which 
eharacr o the piece we execute gives to the meature. Ever.y 
kind of meafure has a movement peculiar to itfelf aud which 
le0gaed in Italian by there words, Tempo giuo. liut betides

in tile order from flow to quick, ac expreffcd by tile words, 
Largo, actaglo, andante, allegro, prefto; and theft: words i t Eng'lifl. 
are rendered, by flow, moderate, pleafiqg, gay, quick. We muff,

a fenfe much more vague than in the Italian. ' " 
Eacli of there degrees is fub-divlded and modified into othert 
alfo, in which we muff diftinguith thole which exprefs the degree' 
only of quicknefs or flowneft% as largfielto, andantinfi, allegretto,  
preftiffimo, and thole, moreover, which'mark thecharaer and 
preflion of the air, as agitato, vivace, gutofo, cotnbvio, &c. Tho' 
firtk.lnay be rendered by all the mttficians, but there are only  
tofe which have fentiment and taft% who feel and render th4 
othet-s. 
Tho', in general, flow movements are fuitable to forrowful 
paffions, and animated movements to the gay, there are, how-: 
ver, often modifications by whidh a patlion fpeaks on the ton' 
ef another. It is true, that gayety cannot be expreffed with' 
flownels, but often the molt lively griefs have the molt unbounde 
language. 
J.'tIOVEMENT, Is alœo the courfe or progrefs of founds from 
flat to '15arp or from fharp to flat: wherefore, when we fay that: 
We mufl- as much as poflihle, make the bars and treble move by' 
contrary movements this fighides that one of the parts ouõl,t to 
arcend, whilPc the other defcend's. Some calI oblique movement 
hat wherein one of the pa,'ts remains in its place wlilf the other, 
:fieends or defcends. 
ß The ingenious Jerome Mel, in imitation of Arlftoxenes, di 
t;nguifhes in general in the human voice', two kinds of move 
tnent$, viz. that of the qeaking voice, which he call continued' 
iovemenr, and which is not fixed tilt the moment we are tilent; 
md that of the tinging voice, which moves by determined inter-. 
vaN, and which he caIls diaCtematic, or intervallative movemen't. 
MUSF. TTg, A Idnd of air fuitable to the inftru,nent of thi'

and original the movement a little flow, bea,'ing generally a bars

and which is tb called on account of this bars. On thfe ai,'. 
we form the dances of a fuitable cha,'a&er and 'which altb havo 
the name of muletres. 
MUSICIAN. This name is given equally to him who corn- 
poles mull% and him Who executes it. The fit. f is alfo called' 
compofcr. (Vide that word.) 
The ancient muffclans wet'e poets, philofophers, and orators of 
the higheft order. Such were Orpheus, Terpandcr, Sterichorus 
&c. Boetius alfo will not hottour with tlte name of mufician, 
him, who only pra&ices the mutic by the fixrvile uI of finger= 
and voice, but him 'who pofilgffc that knowledge by reafon':nd 
tieculation. And it mo,.eover thems, that to faire onc' fell to 
the lofty exprefiions of oratorical-and imitative muli% we rouge 
have

MUSIC, The art of combining the founds in a manner pleaf-. 
i.ng to the ear. This art becomes a fcicnee, and even very pro., 
ou. ncl, when we attempt to find the principles of there combi- 
nations, and the eaures of the plealure which they infpire us with. 
'Ariffides Q9intilian defines inufic as the art of the beautiful, anc 
pica n, in the voices and movement. It is not ffrange, that witI 
definitions fo va ue and ,,eneral,' the ancients have iven a ro- 
,.. g  ß .  P 
dgous extent to the art which they thus defined. ' ' 
We generally fuppofe, that the word mufie is derived frovat 
mufa, becauœe we believe that the mules have invented this art 
3ut Kiteher, after Diodorus, derives this word from an _/gyp- 
tian name, pretending, that it was in dggypt that the mufie be- 
gan firPc to effabllfh itfelf after the deluge, and that the firPc idea 
bf the foudd vas received by the reeds which gre on the bankg' 
6f the Nile, vhen the wln. blew in the hollow of their pipes.: 
Whatever may be the etymology Of this word 'the origin of 
art is certainly more applicable to mankind; and if the words 
did not begin with the air, it is at leaPc certain, that wherever we 
fneak, we finer ' ' ' ' ' ' ' 
'. 'Mufic s na. turally divided into theoretic rr fpeculatlv% ancl

'"Speculative mufie is, if I maybe allowed the exprefllon, the know- 
l..edNe of mufical matter', that is, the different eonne&ions from flat 
to fi3arp, quick to flow, four to fweet, rong to weak, of whict 
the founds are 'fufceptible; conne&ions, which comprehending all 
poffible;komblnations of the mufie and founds, feem to compre-' 
liend all 9 all the eaures of the imprefllons which their fuec'efliom 
may form on the ear and the foul. 
:. Prv/ieil'mufie is the art o applying ancl making ufe of the 
prlnciplea'of the fpeeulatlve; that is, to conduce and difpofe the 
founds in'eonnettion with the confonane% in duration fuccefllon, 
i'n fueh 'a mhhner, as that the whole may produce on the ear the 
propofe'd effe&. It is. this art whleh is called eompofition. (Vide 
this wor'di): :'in regard to tlm actual produion of the rounds by

lourely meehahlc'and operative, which, only fuppofing the faculty

Speculative 
Speculative mufic is divided into tvo part, vlz. the knowletg. 
f the connedScion of the founds, or their intervals, and that of 
their rel'ative durations, that is, of the meafure and time. 
The fir, is properly that which the ancients called harmonlt: 
naufc; it teaches in what conrifts the nature of the air, and 
.marks wh.,rt is confcmant, difl'onanr, agreeable, or ditlearing to 
tJze ear. In a word, it gives a kncvlcdõe of the different 
thods with which the founds affe& th ear by their tone, their- 
œocee, their inte,'val% which is equ&lly applied to the;r concord 
and; t4eir œuceettion.- 
The fecond has. been called rh. ymlc, betaale it treats the founds 
;p {'egad to the timo and quant,ty. It contains the explanation 
of fim'.rhyme and metre, lohg.meafures and fho,-t, li.vely and flov, 
'the eimes and different parts ,nto which they are divided, to ap- 
Laly to them the œucceffion of the founds. 
The pra&ic. al'mufic i divided all0 into two parts, which an-, 
œver to the tvo preceding. . 
That which anfwrs to the harmonic mufic, and which the 
:ncients called melopa, contains the rules for combining and 
,arying the confona'nt and diffonant intervals, in an agreeabl. 
anti' harmonious manner. (Vide Melopca.,) 
The thcond, which anfvers to the rhymic mufic, an½l whlclz 
they call ryttunopma,. contains tle rules for the application of* 
ghe times, feet, ,neafures: 'in a word: for tim pro&ice of rhyme,- 
(Vide Rhvme.) 
Perphy/ius gives another divifion of mufie, whilPc it has for its 
obje& the mute and œonorous movement; and, with. out diftin- 
g.ui/hing it into fpeculafive and pra&ical, there are found in it 
t4e/ix ollowing parts  tim rhymie, for the movements(of dane-. 
i.qg; the metric, for the cadence and number of verfes; the or- 
gaol% for the pa&i.ce of inftruments; the poetic, for the tones 
ad' accent of poefy; 'the hypocritic, For the attitu. des of panto- 
m. Jmes; and the harmonie,-for tile air. ' . 
ß The marie s divided, at prelbnt, more timply in. to melody and 
h;rnon¾; for the' r!ff. mic is no longer remarded amongf us, anti 
the v0etic is very trilling, nce our vcrfi's, ,n airs: take rcarly' 
tleir'mealbm from muff, c, and lcffc the littl which they receive 
œrom it by thcmfelves. 
By melodY, we di-e& the fucceflion or,he founds fo as to produce 
sin agreeable air? (Vide Mlody, Air, M0duiafion.) ' 
Harmony conrifts in uniting to. each of t;he founds, in a regular 
f,cceflior] two or more other lbunds, whig;h, fh'iklng the car at 
the fiunc lime, flatter it by their cdqcurren. cc: (Vide Harmony.) 
. W.c might, and, perhaps, ought to divide tll e mufi½ in. to natural 
aged imitative. The firl conlined to. the plt)(ie of t[!c tbund 
onllt, andoa&ng oa th'd 1i:nfe bn)'' cannot :arry i.tl impreltlons. 
i6 ihc heart, and gives fenrations only mole or 'lel's agreeattic. 
Such is the mufic of the longs, hymns, cantles, and of all the 
,airs, which are only combinations of melodious founds, and al 
mufic in general which is not harmonious. 
The fccond, by inftexi0ns lively and accented, and, as it wet% 
]eaking, cxpretTes all tile pardons, paints every piure, reader 
e'er¾ oh. iceør, fubmlts the whole of nature to its ingenious imita- 
tionsd ahd, by this means conveys to the foul of tile man thof 
tntimcnts proper for moving it. This truly lyric and theatrical 
mufic was that of' ancient foetus, and it is illat which at pre/ent 
we apply to the drama'% cxecutcd in mmq½ on our theatres. It 
is only in this mufic, and not iv/ the harmonic or n=turat, that 
we rnu leek t}e caut of tile prodigious effe&s whicl i formerly 
produced. How much œoever we may thek for moral effe&s 
the phyfic of founds onl% we fhall mver find ttmm and our 
reaFoning will he without mderftanding. 
The aficient writers differ greatly on the nature, the 
extent, and tile parts of mufic. In geheral, they gave this word. 
much more extenve than that which remains to it at preFen% 
They not only comprehended, under tile name cf mut]c, as we 
have Feen, tile dance, gel'cur% and poetry, but even tile colletion. 
of all tile iiences. Hermes defines mufic ,as the knowledge of 
the order in every thing. This was alfo the dorine in the ihol 
of Pythagoras, and that oi Plat% 'who taught, thai every thing 
in the univerfe was mufic. According to Hefy:hbas, the Athe- 
iians gave tile name of mufic to all tke arts; and all this is no 
longer aPconifhing, finee, tha: a modern muffelan has found 
mufie the principal of all references, and the foundation of every' 
fcienee. From thence are all thole tblime pieces of mufic, whie.l. 
the philofophers have handed down to us, divine mufic, mufie 
mankind, eelePdal mufic, terreftrial, a&iv% contemplativ% enun,- 
ciative, intolie&ire, oratorical, &c. 
it is under theFe raft ideas that we rnu{ underfraud feveral 
aiTages of the ancients on tnufic, which would be unintelligible 
 the infe which we at prefent give to this word. 
It appears that mufic has been one of the firft arts; we find it 
tnixt among the nofl: ancient monuments of human kind. Iris allb 
very probable, that the vocal mufic was found before the intkru- 
mental, if' among the ancients there ever was a mufic truly 
lumental; i. e. formed for inftruments entirely. Not-only' 
ß mankind, before ditizovering any inftrument muf have made 
bfervations on the dif[erent tones of their voice, but they muff 
have :learned very early by the natural concert of birds, to 
dify their voice and taroat in an agreeable and niclodious manø 
her. After this, the wind inftruments inuft have been the tirfl: 
i. rlventccl. Di0dorus and other authors am'ibut: the invcntloa 
to 
to an obfervation of the blowing of the wind in reeds or otk ea 
hollow plants. This is alfo a fentiment of Lucretius.

in regard to other .kinds of ini!ruments, the fonorous chord 
:are fo common, that mankind muff have early obferved the dif- 
'erent tones which have given birth to the diff'erent chord inftru- 
xnents..(Vide Chord.) 
Thole inftruments which are itruck to draw a found from 
hem, as drums and tyrohals, owe their origin to the deafenirt 
iaolfe which hollow bodies emit when ftruck. 
It is difficult to leave there geneealities to fix on rome certainty 
or, the invention of mutic reduced into an art. Without aftending 
to times before the flood feveral of the ancients attribute this in- 
?endon to Mercury, as well as that of the lyre. Others fi/c o 
Cadmus as the ihkroduEtor of it among the Greeks. who. flyinc 
œrom the court 6f the king of PhamicYa, carried ¾ith hlmqntg 
Ireece, the muffclan, Hermione, or Harmony; from wlsenee iœ 
rould fotlow that this art was known in Phoenicia befo?e Cad- 
gnus. In a part of-.ISlutarch% Dia'logue on Mufic, Lyfias names 
dtmphion as the in,entor; in another Soterichus thys it was 
aft, pollo; -and in a third he feems to give the honour to Olympus: 
there is no agreement on this matter, and, it muff be confeffed 
it is of tttlc confequence. To there firft inventors fucceeded 
Chiron, Dern0docns, Herme% Orpheu% who in the opi.nion of 
œome, invented he lyre. ' 
After thor% -ame Phamlus then Terpander, contemporary of 
Lycurgus, and who laid down the rules ofmufic. Some attribute 
to him the investion of the firft modes. Laftly, we addThales an 
'Thmniris, who is laid to have been the inventor of mtrilcal inftru- 
aments. There great muffclans lived molt of' {hem before Ho-

As the ancient arehots exprcfs themktves very obfcurely 
the inventors of mnfical inllruments, they are ajlb very unintel- 
'iigible on the initruments themfelves. Hardly do we know an9' 
thing more of them than their names. (Videlnllrument.) - 
Nlufic Was in its greate erieera an.ong the different people of 
ntiquity and particularly among the Greeks; and this elleew 
was proportionate to the power and furFrifing effes which they 
attributed to his art. Their authors do not think they have 
given us a too great idea of i% when they told us it tvas ued 
heaven; and that it formed the chief a.mufiment of the gods and 
'/buls of the bleffed. Plato does not hefttare to fay, that there 
ban be no change in rnufi% but there mull be one alfo in 
conP, imtion of the /'tare; and he pretends that tbunds may b 
affigncd capable of fairing the ideas of a bale tbul infolenc% 
with all their contrary virtues. Arillotle, who feems to hav 
written his political works only to oppofe his fentiments to thoe 
.of Plat% is, however, in eoheord with him in regard to the 
power of mufie ovet' the manners. The judicious Polybius tells 
us, that tnutlc was neceffary to fweeten the manners of the 
'cadians who dwelt in a. country where the air was cold and 
wintry; that thot of Cynetes who negle&ed mufi½, furpuffed all 
the Greeks in cruelty and that there was no country which was 
equal to it in crimes. Athenzeus affures us, that in former 
'times, all laws, human and div-in% exhortations to virtue, the 
knovledge of what concerned the gods and heroes the lives and 
&ions of illuftrious men, xvete written in veri, and fund pub- 
licly in choirs by the found of inllruments; and we fee, by fa- 
i:red writings, that 1iach were the curtoms of the Ifi'aelltes from 
the earlleft times. There had been no method found more effi- 
cacious to endray% on the minds of men the principles ofmo- 
rallty and love of virtue; or, rather all this was not the effe& 
<)fa premeditated defign but of the grandeur in its fentiments 
and the elevation of the ideas which lought by proportioned fie- 
cents to form to themfelves a language worthy of them. 
Mufic formed a part of the llndy of the ancient Pythagoreans. 
They ufcd it to exdite the lbul to laudable a&ion% ad to-nfla,ne 
ech other with the love of virtue. According to the philofo- 
phers our fouls xvere formed of nothing but harmony; and they' 
expedted to re-eflablifh, by the means of tnthal harmony, the '.' 
intulleOu'd and primitive o,e of the faculties of the tbul; hat is 
tO Ihy, that wlficl b according to them, exilled in it before it 
animated our bodies, and whilll it dwelt in heaven. 
Mufic is at preint thnk from that degree of power and 
jelly, I0 far as to make us doubt of the truth of thot wonders 
whiclx it forn,e,'ly pcrœormcd tho' attofled by the moff judicious 
U u hiRorians 
6z  U 
lfiftorianv, and graveqc philofopbers of antiquity. FIowever, }a 
modern hiftory, we may find rome timilar fas. IfTimotheus 
excited the fury of Alexander by the phrygian mode, and caln,ec[ 
it by the lydian, a mufic, Pcill more moderate, has furpaWed it, 
by exciting, they fay, in Errie, king of Denmark, fuch a fury 
tlat be kill'd his molt faithful fervants. Douhtlet there wretches 
were lefs fenfible of mufic thhn their prince, othervife he might 
l:ave run half the danger. D'Aubigny recounts another hiftory 
quite fimlar to tlat of Tim0theus. He tells us, that in the 
-eign of Henry Iti. the mufician Claudin, playing at the marti- 
nge of the Duc de Joyeufk, in the phrygian mode, animated, hot 
he king, but a courtier, who fo far forgot himlIf as to draw his 
œword in the prefence of his forereign; but the muffclan quickly' 
.calmed him by taking the hypo-phrygian mode. This is faicl, 
with as much affurance, as if the mfffiian Claudin. knew in what 
.conrifted the phrygian and hypo-prhygian modes. 
I'f our mufic has little power'over the affe&ions of the foul, in 
ß return, it is capable of aceting phyfically on the body, as in the 
lfif'cory of the Tarantula, too well known to want mentioning 
here: as a proof of which, I bring the Chevalier Gafcon which 
ovle mentions, who, at the found of a cornemufe, or bag-pip% 
could not contain his urine; to which fhould be added, what the 
fame author recounts of rome women, who burft into tears at 
he hearing of a certain tone, with which the reft: of the audience 
were not at all afl:cCted; and I know a woman of fafhion at 
Paris, who Cannot liften to any kind of mufic whatfoever, with-_ 
out being feized with an invohmtary and convulfive laughter. 
We read altb in the hlftory of the Academy of Sciences at Paris, 
tlnat a muffclan was cured of a violent fever by a concert per- 
œormcd in his chamler. 
Sounds aa even on inanimatcd bodies. as we may fee by the 
tiaaking and rcfonance of a ibnorous body at the found of an- 
other, with which it is conneceted in rome relycert. Morhoff' 
mentlon. a certain Peter, a Dutchman who broke a glafs by the 
œ,und of a voice. Kirtcher fpeaks of a large fton% w'hich tre.m- 
l!ed at the found of a certain pipe in an organ. P. Merfenne 
ieaks alfo of a kind ofwaggon, which the playing of the organ 
t]mok'as though it had been an earthquake. 
Boyle adds, that the Stalls often fhake at the found of the or-' 
gan, and that he has himtlf felt thein tremble under his hand at 
he und of the organ or the voice and that he has been af- 
'threcl, that thole which were well rmed, trembled all- at rome 
determined tone. The whole world have heard m½:ntion of the 
t'amous pillar at the chqrch in Rheims, which fi:ntibly fiakes at 
the found of a certai.n bell, whilft the other pillars continue im-' 
moveable; 
 U 
movealle: but that u,hch tranfmits the honour o{ the marvel- 
1ous to the rotund, is, that this fame pillar equally fiakes when 
the clapper of the bell is removed. 
All thelh examples, the greate part of which belong rather to 
tle found than to the' mufic, and of which phvfie may-give 
rome explanation, neither makes them more credible or 'intelli 
glble to us, tho' the ancients held them in mufic as marvellous 
and ahno divine. Many authors have puzzled their brains to 
endearour to give a cadre for tlem. Wallis attributes them 
partly to the novelty of art and partly rejes them on the ex- 
aggeratlon of authors. 
Others imagine that the Greeks, more fenfible than ouffelv.es 
by tle conitution of their climate, or by their method of living, 
might be mov'd by things which could make no impre,on 
us. Monf. Burette even in adopting all there fa&s pretends 
that they do not prove the perfeXion of the !nufic which pro- 
duced them: he fees nothing in it, but what the fad fcrapers 
a coun'try village might have done, in his opinion, quite as welI 
as the firfi muffclans of the worM. 
The generality of there fentiments are founded on the perf- 
fion we are in of the excellence of our ranfie, and the contempt 
'e have for that of the ancona. But is tMs contempt as juffly 
founded as we pretend ? This has been fevera! times .exmi; 
and when we conrider the obfeurity of e matter, and the in- 
fue.iency of judges, has great need of undergoing a 'betr 
feareh. Of all thole who hav yet empyed themfelves

Rhythmi, appears to have be difeuffed the quaion, and drawg 
te neare to truth. I have throtvn f6me ideas thereon in

It has en mfck wi%ed to the rome fragments of ancient

leek in vain to find in this air any energic accents capable o

them, and recalling the idea of their country, tlxeir former plea-. 
hres, their youth, and all their joys of lite, excite in them 
hitter forrow for the 1oE of them. The mufic does not in thi- 
care :& precifzly as inufic, but a a memorative fign. This air 
the' it continues the fame, does not produce, at pretEnt, the faro=

rggret it, but when reminded. So tru it is, that it i not im

The method, by which the ancients prlck'd their notes, was 
eabtified on a wry fimp. le foundation, which was the connee- 
{ion of cyphers; i.e. by the letters of their alphabet; but in- 
ead of confining themfelves on this idea to a froall number of 
charaaes eafy to retain tlmy were to in multitudes of different 
figns, with whicN they cnnfufed their mufic in return, fo that 
riley had as many methods of marking as genera and modes. 
oetius took froth= Latin alphabet cbaraers corretpondlng to 
there of the Greek. Pope Gregory perfe&ed this method. 
oz 4, Gui d'Arezz% benedi&ine, introduced the uf of ave, 
(vide Stave) on lines, on which he marked the notes in form og 
points (vide Notes) expreing by their pofition the elevatio 
or the lowering of tim voice. Kircher however pretends that 
this invention was prior to Gui, and in effea I have not fee 
in the writings of this monk that he claims it to hinfelf; bur 
he invented the gamut and npplied to the notes of his hexachord 
names drawn from tl½ hymn of St. John Bapti which they 
prelErve at prelknt. This lna% laffly born for mufic invente 
different fnffruments called polyplear% their as the harpfichord 
fpinaet viol &c. 
The chara&ers of muff% have, according to the general 
nion, rgceived their lat confidetable augmentation in 33o at 
the tim% they thy when Jean de Muris call'd improperly by tm 
jean tie Mmurs or de Muria do&or of Paris, the' Gelher makes 
ldm an Englilhman, invented the different tigurc, ot the notes 
which exprcg the durntion or the quantity, and whiclt w now call 
tmi-brves, minums crotchets.c. But this tntlment the*

/mainder, this great muffclan has had, like th'e king of poets, the 
onour to be claimed by different people; for the Italians 
Fretend he is of their nation perhaps deceived by a fraud or 
error of Bontempi, who calls hm Penigino in,cad of Paniglno. 
Lafus is, or feems to be, as I have fold before, the fir who 
las written on mufic; but his works are Ioff as well as Cevera[ 
other' books of the Gt'ecks and omans on the fame rubieS. 
rioxenes, the difciple of Ariotle, and chief of the muffcat 
fe, is the mo ancient author who remains to us in that tki- 
ence. After him cnes Euclid of Alexandria. Ariides in 
tilian wrote after Cicero. Alypius comes next; then Gauden- 
tius, Nicomachus, and Eacchius. 
Mate Meibomius has given us a beautiful edition of there. 
feven Greek authors, with a Latin tranflation and notes. 
Plutarch has 'ritten a Dialogue on Mufic. Ptolomy a cele 
brated mathematician, wrote, in Greek, the Principles of Har- 
mony, about the time of the emperor Antoninus. This author 
preferyes a medium between the Pythagoreans and Arioxeneans. 
 Ionff time after, Manuel rtennius wrote alib on the fame

1MUTATIONS. By this term were call'd, in ancient mute, 
generally, all the pal%ges of an order, or fubje& of one air to 
another. 
Ariftoxene defines the mutation as a kind of puffion in tl,e 
order of melody; Bacchius, as a change in the fubie&, or the 
tranfp0fition o(a lile into a'n unlike pl'ce; Ariftide O_.9intilian, 
as g variation in tile propored lyllem, and the chara&er of the 
voice; Martlanus Capella, as a tranfition of the voice in another 
order of ound. 
All there detinltion, obfcure and too geaet'al, have need of 
being cleared by divjfions, but .authors do not agree better on 
there divifions than on the defihition itfelf. Howeverø we jufl: 
gather, that all there mutation may be reduced to five principal 
kinds. 
Fixf, A mutation in the genus, when the air pati'd, for in- 
ttance,' from diat9n. ig_.t.o chromatic or to the enharmonic, and. 
reciprocally. ;-. 
Secondly, Iu the fytte;-..when the modulation united two riff- 
joint tetrachords, or feparatg&from them iwo conjoint, which 
nfwers :to the pairage of the B fharp to B fiat, and reciprocally. 
Thirdly, In tire rood% when, for inCrance, we p'ati from the 
/1orlc'to tile-phrygian or lydian, and reciprocally, 
Fouvthly, In the rhyme, when we pafd from quick to flo 
or from one meathre to another.

NOTES. Signs or charaers ufe 4 to nark, that is, to' write 
the mufic. 
'The Greeks made ufe of the letters of their alphabet to mark 
their mufic. lIoreover, as they. had twenty-four letters, and as 
their areatel[ tftem, whiclx was only of two' oaves in a fame 
node,, thd not exceed the number of fixteen iounds, t would. 
œeem that the alphabet nuft have been more than fufficient to

the rhyme was thfIiciently determined by the metr% without 
there being v'anting for that ablblute powers, and tigns peculiar 
to rnxfic; for the' by ihperabundance they had charaEters altb 
o mark. the different fecr, it is certain, that vokal mhfic was nee 
in want of it; and inffrumemal muff% being only the vocal 
play'd by inffruments had neither aced of it s fince the words 
x'ere written, or the fymphonif[ knew them by heart. 
Bat we mu,ff take notice, in the firf( plac% that two fame 
founds one while at the extremity' and another while in the 
lMctle of the third tctrachord acco,'ding 'to the place wherdin 
the dlsjunEtion is made, (Vide theft wol'd) they gave to each of 
there 'bund% .names and figns vlfi'ch exprcfld there different 
fitnations. Sccondly that theœe fix teen feuDds were not' all the 
three in the tlrce genera; th'at there were rome common to the 
three s and others peculiar to eaclx; axxd that notes were confe- 
queatly

c was.diffcrently noted for int'ruments than for the voice, as 
;'e have at preent, for certain chord inftrument% a table which 
has no reœ½mblance to hat of ordlnary mufic in the leafc. 
ly that the ancients having as many as fifteen different modes 
according to :the numbering of Alypius, (Vide Mode) it was 
ceffary to appropriate charaers tO each mode, as we fee in the 
tables of the fame author. All there modifications required 
rnultltude of.fin% for which the four arid 'twenty letters were 
very far from furricing. From thence arlfes the neceffity oFufing 
'the ame letters for fryetel forts of notes, which obliged. them to 
giv to thole letters differe.nt fitfatios to couple them maim 
hem, and lcngtlen theni in different fenres. For inffahc% the

Bv dombining all the modifications which there 11fferent 
cum:ances required, we find nearly I6zo different notes, a ptø: 
]ig{ous number, which mu have rendered the udy of mufic 
thing of th greatet"c difficulty. It was certainly fo in the time 
Plato, who ad¾iFes young men to fpend two or three years in

.The notes had for rome time no other ufe tltan to mark tTe 
leg.'ees and differences of intoneion. They were all in regard 
ß to duration of equal powers; and received, in regard to this, no 
other difference thau tlxol of long and fiort fyllables, on which 
they werefuhg: It is nearly in this condition that the ehureh- 
utic the Catholics has continued to this day; anti the mufic of 
the pfalms among the protean, ia ill more iraperle&; 
iince, in their u.l, tl lengths of the breves, or the rounds of the 
ninums, were not even diinguified tho' tliei preferred two 
different figures. 
This indiin&ion of figures continued in the general opinion 
as far as x338, when Jean de Muris, ado&or and canon of Paris, 
ga% it is pretended different figures to the notcs to mark the 
connc&ions of duration which they had between each other: he 
altb invented eertaln figns of meatr% eal!ed modcs or prolations 
xo deterrain% in the confie of an air if the reference of long to 
ort ould be double' or triple, &e. Many of the figures  
longer fub. There.have'been others fubttituted in their place 
at different times. (Vide Meafure, Time, Power of Notes.) 
ide al, at the word Mufic, what I have/hid of t]is opinion. 
T read mufic written by notes, and to render it exa&ly, there 
are eight things to be confidered. Fir, the cleft and its pofition. 
Seeondly the diefis's or B's flat whith may accotnpanf it. 
lfirdly the pIace or pofition of each note. Fourthly, Ns in- 
'terval, that is its conne&ion with that which precedes, or with 
the tonic, or tbme fixed note whole tone we have. Fifthly, its 
ggur% which determines its powers. Sixthly, the time wherein 
.it is found, and the place it occupies. Seventhly, the dieils g 
.fiat, 0r accidental B firp which may precede it. Eighthly, tl? 
.kind of the meafure, sad ch=raer of the movement. And all 
this, without reckofing either the words or t11ables to whicrx 
.each note belongs, the accent, or the expreon fuitable to the 
fsntiment tvhereon we refleX. One of. thefe eight obfm'vationa 
only omitted, may make it jar, or play out of time. 
The mufic ha had the lot of thol arts which improve but 
fiowly. 
The inventors of notes have bn attentive to the ate'onl 
le. rm'n t was n their time, without refit&lug on tha.t to whiclx 
it might be railed; and in the end their marks have been found 
b muclx the more ticfelly% as the art has been fince improved.

lrc may recIuce its fauJt. to three principals: The firc is the 
multitude'oF figas and their combinations, wfiich Ioad the mind 
:red memory of beginners in œuch a maimer, that the ar is fOrm'd 
an the organs have acqulrcd habit, and a ncccr¾ facility 
long time bcœore they are able to ting d livre ourerr; 'froin whence 
t 11ows, that the difficulty is intircly in an attention to the 
rules, and not at all 'in the execution of the air, The fecond, is 
the tittle evidence in the nature of major, minor, di. miniihcd, and 
œuperfluoas intervals, all }ndittincly confounded in the fame 
fitions; a fault of fuch influence, that it is not only the principal 
cauf of the flownels i the progreli of œcholars, but, moreore% 
there is no muffclan form'd, who can fail of being incommoded 
in the execution. Wh'e third, is the extreme diffufion of tho 
chara&ers, anti the too great extent which they. take up, which, 
joined o thole lines, to thole .flares fo inconvement to trace, be 
comes a fo'urce of,,embarraffment of more than one kind.. If the 
firff advantage of inffituting figns, was, that they fiould b'e clear 
the tbcond is, that. they thould become coneliE; what judgment 
then we forin of an order oi figns in which both the one and the 
other are wanting ? 
Mufician% i't is true, cannot fee any thing of thls.' Cullom 
has habituated them to this. Mufic to them is not the know- 
ledge of tb,,nds; it 'is that of crotchets, mlnums, demi-crotehets 
&c. &e. As foon as there figures ceafe to be prefent, they can- 
not fatisfy themlElves that they .fee mufic. Moreover; what 
they have learnt with difficulty, how can they render it eafy to 
others ? It is nbt then the mufician who flould be confulted 
herein, but the man who underfiands muff% and ho has reftcacti 
on the b, rt. 
There are not, in this Init clafs, two that agree in the errors 
of our notes; but ill thfe faults are eafier to know than to 
corre&. Many have endeavoured at this corre&ion without rue- 
eels for rome time.' The publi% wkhout anlr great diti:uflion on 
the advantage of the figns propoid to iq always embrace thole 
vhich are atready ettablifhed and muff' always prefer a bad me- 
thodoi kiloWlng, to a better of learning. Wherefore, becau& 
new'fyftein is reje&ed, is no folid proof f any thing more, than 
that the author came t0b late and we may always diieu and 
compare the two fyffem% with any regard on this point, to the 
judg,-nent of the publi:. - -' 
All the methods of m/irking note% which have not had for 
their grand law the evidence of intervals, do not teem to me woY-.. ' 
thy ot the trouble of being removed. I will not then make any 
ttop at that of Mgnf, Shuveur which may be feen in the Me-

the intervals being expreffed by figns intirely arbitrary, and 
without any true connexion with the thing reprefented, efcape 
the mof attentive eyes, and can be fixed on the memory alont 
for of'.wha't-fervice are heads Mifferently figured, and tails diffe- 
rently direeq:ed,.to the intervals which they ought' to exprefs 
uch figns as thole have nothing in tlaeln xvhiix hould make 
thean preferable to others; the neathels of the figure, and the 
little place which it takes up, are advantages. which might 
found in a fvfem entirely different: elsanee may have given the 
œrf figns,.ht we muft halve a choice more peculiar to the thing 
in thole xvhich thould be f&ht'tituted in their place. Thot which 
have been propold in 743, in a little work, intitled * Differ-

NOTES Ot 7 TASTE. There are two kinds of them. The 
one which belongs to the melody, but not to harmony; fo that 
tho' they enter into the meafur% they do not in the concord: 
there are marked in full. The other notes oftaffe, entering nei- 
ther into harmony or melody, are marked only with finall notes, 
\vhich are not reckoned in the mealhre, and whole very rapid 
duration is taken on the note which precedes, or that which fol-

IV'. Lafily, the o&ave has this propriety alfo, tile mof[ 
Iar of all, that it can be added to itfelf. tripled, and multi'plied 
at plealure, without changing its nature, and without its produ& 
ceating to be a confonance. 
This multiplication of the o&ave, as well as its divion, 
however bounded in regard tcr t,s, by the capacity of the auditire 
o,'gan; and an interval of eigh't o&aves already exceeds that 
capacity. (Vide Extent.) Thff o&aves themœelves lore tbtne- 
thing of the;r haanony in being nrt, l'tipied; and, beyond 
certa'in meathre, aH the intervals are lefs eafy for the ear to 
catch; a double aave begins already to be lefs agreeable tharr 
a timpie; a t,-iple than a double; laftly, in tile fifth oave, tile 
extreme diftance of its f6unds dcprives the contbnance n'early 
the who?e of its beauty. 
It is from the oCtav that'we draw the ordained generation of 
all' the intervals by harmonic divifions and fuh-diifious. 
vide harmonically the oCtave 3- 6. by the number 4- you will: 
have on one fide the fourill, 3' 4- and on the' oder fide tlte 
fifth, 4- 6. 
Divide, in the fame manner, the fifth, Icy.: . harmonically 
by the number I2. you will have the minor third, .o. . anc 
the ma5or third . x.f. Latt[y, divide the ma. ior third 72- 9 o. 
again, harmonically by the number 80. you will have the ml- 
nor tone 7 . 8'0. or 9- 'o. and the major tone 80. 90. or 8. 
We mu take notice, that there harmonic di'vifions give always 
two unequal intervals the leafl3 of whi'ch is in flat, and the' 
greater in fharp. If we make the fame divions i.n arithmetical. 
proportion, we fhall have the finalle interval in flaarp,. and the 
greater in flat. Wherefore tlie oCta'e 2. 4- a,'ithmetically di- 
vided, will immediately give. the fifth 2.3' in. flat, then the ourth, 
_q.'4- in flaarp. The firth. 4- 6. will firft give the ma5or third 
3- 5" then the minor third 5.' 6. ancrfo with tlie reft. We fliouldl 
have tile fame connections in contrary fenls. if, inilead. of tak- 
ing them, as 1 do here by vibrations, we took them by the 
!ength of'the chord.. 'Fhis knowledge is betides. of lttl utility 
in itfelf, but it is neceffary to underpcand the ancient authors. 
The complete and rigoro?s lrPcerrr.of the ocøcae is ½ompof(-d 
oœthree major tones two minor, and two ma. ior lhmi-tonev. The' 
temperated t3tLem is o; fi:e equal tones and 2 lhmi-tones form- 
ing together as many diatonic degree on. the feven founds of the 
amut, as far as die 0ave of the firPc. But as every tone may 
e divided into two lkmi-tonus,. the fame oCtave is divided allb. 
ck,.omatlcally into twelve intervals,. each of a fetal-tone, tile 
yen precedent of vlxich etail their namc and the five others. 
take each the name of the. diatonic found neareft. to i below by 
dieils, and above by B flat (ie cale.) 
I do not leak here of dimlnied or fuperuous oave% 
cauqe this interval is feldom changed in melody and ever 
harmony. 
It is forNdden, in compofi:ion, to ake two oaves together 
between different parts, particularly in a timilar movement; but 
this is permitted, anti even elegant, tonned on putpole, and 
propos, through the whole of an air or a period: It is in this' 
manner, that in tveral concerto's all the parts take by intervals 
the rippieno, in oave or uniFon. 
On the rule of the oave. (Vide Rule.) 
TO OCTAVE. %Vhcn we force the air in a winff inrumen% 
the found immediately aFcends to the oave: this is what we 
catt to oave. In rengthening the inlration thus the air 
being inctold in the pipe, and con,rained by the extior 
is obliged, in yiekling to the quicknet of the otillations, to be 
divided into two equal columns, having each the half of the 
length of the pipe: It is in this manner that each of thefe halves 
founds the oave of the whole. A chord of the violincello 
oaves by a timilar principle, when the roke of the bow is too 
rough,. or too near the bridge. It is a fault in the organ when a 
pipe oaves. This happen. from its receiving too much air. 
ODE. A Greek word which fignifies an air, or for, g. 
ODEUM. This was, among the ancients, a place defiincd 
for the repetition of the mufic which was to  fung on the 
age, as in the opera of Paris, is the little theatre du Magafin. 
The name of oderan was givea fometimes to build'ings which 
had no connexion with the th. eatre. We read in Vitruvius, lae 
Pericles ordered an odeurn to bg built at Atlxens, where theI 
dituted foe the rewards of mufic; and in Paufanlas, that Herod, 
the Athenian, con,ruled a magnificent odium, as- the thpulchre 
of his wile. 
The Ecclcfiafiic writers dcfign alfo rome times the choir of 
chin'oh, by the word odeurn. 
OPEKA. A dramatic and lyric Ieacle, where we' ufe our 
endearours to reunite all the charms of the fine arts, in the 
prcfentation of a Iqonate aion, to excite, by tim alfiance of 
agreeable ten/htiors; the intereft and i.11fion. 
The conffitutive parts of an opera, are the pem, the mufic, 
and .the deco,.ations. 13y poetry we tcak to the mind; by 
fie to the ear; and by painting to the eyes; and the whole 
to be reunited to move the Itcart, and convey to it, at the thm

hc a o6 con,b}ning the (ounds ag,-ecably, may be viewe 
nder two diffrenl afoes. Confidered as an initutlon of 
ture, mufic gounds its effc by the tnfation anti phyfical plea- 
fur which ?eful{s from it, by tile melody, harmony, and rhyme. 
Such is Or4in'a{y the church-mufic; fuch are the tunes for 
dancing, and tholh of )ngs. But as' an egential part of the 
lyric fcene, whole principal oie is the imitation, mufiz becomes 
oneof the fine arts, capable of painting ere,'y pi&ure of ex- 
citing e,'y fentlment, of harmonizing. with poetry, giving it a 
new ,'ength, embellifl,ing it with new charms, and triumphing 
byjts means atthetime that it crowns 
The founds of the qeaking voice, neither fuained, nor bar; 
monious, are not app?ciable, and, cofequently, cannot be agree- 
ably allied With thole of the tinging voice and in,-uments, at 
leaR, i'n our Ianguages too much removed f,'on a mucal cha- 
ra&c,-; for we cannot underand the paflhges of the Greeks in 
their method of reciting, but by thppofing their language to be 
ucc.ented in tch a manner, that the infle&ions of the 
in a thilained declamation, form betveen themtIves mufical and 
appreciql }ntervals.; fo we may t}e that their theatrical pieces 
were a kind of opera, and 'tis for this fame reafon, that there' 
could be nq opera prppe,'ly called tb among them. 
By the diculty of uniting the air to the dit}ourfe in our 
languages, it is eafy to perceive, that the interventionbf the mufic 
as n fir, tial 'part, tour give the lyric poem a charaer differ- 
ent fr,n that of trag.dy and 'comedy, and make a third from 
itin the nature of adnama, which has its particular rules; but 
thei differences cannot bc determined {ithout  perle& know- 
ledge o thg.igrt .added, of the methods to untie it with the 
words, anl of its natural relation with the human heart: Rutlies

inuI be left for a pen tbrmcd to brighten evgry art to Ihew 
tiot who proleti them,'the principles of their rules and to men 
of ta2% the fourcos of their pleathres. 
Coniinhg roy foil, then, to tbme obtbrvatlons on this tbje 
more hoic;;l than i'c'albncd, I thalI fir take notice, that the 
(ircckg had not in their hOttr% a lyric genus as om'tblvcs; and 
whist they called by that nae was not at all timilar to. it. 
they hd lauch accent in their laugunge, and but little no(

declamatory; lb that the. jr airs were little mre than a

regard to what they called iyric genus' in particular, it was an 
h.roic poety, whof5 fyle wa pompous an.d figured, whidh was 
accompanied by the lyre or citha. ra, in preference to every 
other inru,nent. It is certain, that the Greek tragedies were 
rccited in a manner very {imilar to the ale, that they were ac- 
co,npanied with infh'uments, and that chorufis .c. ompofed a part 
of them. 
But if, on this account, it is thought that they were opera% 
tlke to ottrs, we murk then imagine opera's without airs, for i' 
feems to me fufficlently proved, that the Gredk mufic, vithou, 
even excepting the inftrumental, was nothing more than a tea 
recitative. It is true, that this recitative, ,hlch reunited 
charm of the mufical founds to the whole harmony of poeti'y.. 
and to all the force of declamation, murk have much more energy 
than the modern, which cannot enjoy one of there advantage:. 
but at the expence of the reft. In our living languages, which 
in general carry with them the.fcent of the rudenefi of tha 
climate wherein they are original, the application of the mufit 
.to the words is much leO- natural. _.doubtful profody is a bat' 
agreement with the regularity of meafu,'e. Syllables mute vith-.

a armouv little felt in mufical rhyme, and is mceffantly oppofet 
to the div'erfity of powers and their movements. Here are d;f. 
ficu}ties which flould be conquered or eluded in the invention o, 
the lyric poem. It was then endea_voured, by a choice of words, 
turns and verlks, to make a proper language; and this languag% 
which was cal}ed lyri% was rich or poor, in proportion to tlxe 
t,vcetnell or roughneli of that from whence it Was &:'rived. 
Having, in lbme refpeOs, 'prepared the Words for the mufic, it 
was then'.necelEry to apply' the mufic to tile words, and to ren- 
de' it proper in fudh a manne,' on tlc lyric ti:ene, that the whole

This method of uniting on the. theatre the mtfJc to tile 
Which among the Greeks was fufficient for the intere and il- 
lufio% becaufe it was natural, by the contrary realbn could not 
rupee among us by the fame ending. In lienlng to a con- 
rained and hypothe{ic language we.have tbme trouble to con- 
ceive what is lhid: with much noire they afford lirtte emotion. 
From thence arifes the nece$ty of introducing a phyfical pica- 
lure to the aance of the moral,' and to/upply, by the att-ac- 
'tion of harmony what is wanting in the energy of expre/tion. 
XVherefor% the lefs we know how to touch the heart, the mo'e 
we mu endearour to flatter the ear. We are obliged to lbck 
in fenlhtion, that plealre which lntiment denies us. Hence is 
the origin of airs, choirs, tyrophony, and oF that enchanting 
melody with which inodern mr,fie is often embellifhcd, at the 
expence of the poetry but which the man of tafie banirises 
from the theatre, when heis flattered without emotion. 
At the fir rilb of the oper% its inventor, wifling to elude 
what had very little nature, viz. the union of mufic to the cli/ 
courf% in the imitation of human life, telhired to tranlort the 
fcene to the heavens and hell and thro' an ignorance of making 
nmnkind fpeak they chol rather to make zods anti devils fil, 
than heroes and epherds. Very ioon the marvellous became 
the foundation of the lyric theart% and contented with enriching 
them&Ives with a new genus, they did not even pay attention to 
fi,id whether they hadcholbn one that was thitable. To 
tb firohs an illufio% it was necefii, ry to drain all that liuman art 
could imagine molt teducing amongfi a people wholb. mo ardent 
patrons wei'e the love of pleaIbrd, and that of th fine arts. 
That celebrated nation, in tvhich there remains nothing of its 
ancient grandeur, but that of the ideas in the finearts lavified 
all its tare and ingenuity to give this new lpe&acle all the eclat 
it oodin need of. Through the whole ofItal 'eretken thea- 
tres equaltothe palaces of their kings, and m elcganc% like

$Vth all this theaion conlinued cold and every fituation

briOni'ration o'f con0eniporari.es; who knew.ho better. They even 
,congfatlitted it on the dilEover¾ of fo fi,le a genus.  Here, 
a' Ihid they, is a nhw. principle j6ined to thofe of AriPtotle: here 
 i.s 'admiration joined with teri'or and pity." Wiley did not perZ 
ceive that 'this ap0arent richnefs was at bottom no more than 
riga of cerility', as the floverk which cover the field before hat- 
veil. It was a want Of knowing how to touch the paffions that 
they wifhed t'o furprife } and this pretended admiration, was, in 
effe'', no. more than a childlib ailoniflment, which they ought to

movement, the harmony and airs was not i,ldifferent to the things 
Which they had to flay, and that, contqut, ntly, the effe& of the 
rnufic alone bounded thus far to the tnt-s, might eve,i reach the

It is certain, that as much of the pomp mig'lt have been re: 
.rnoved from the fpeacle as was added to the intere R of the 
.tion; for tile more perions there are who a&, lefs we are em- 
ployed in the obje&s which furround them .; 'but Rill the fituatim 
of the fcene muPc be fuitable to the aors who fpeak therein 
;nd the imitation of nature, often more difficult, and always. more 
a_reeable, than that of imainarv beings, became more intreRin 
a' it became more natural. ' A b'eautiful palace, pleating gardens 
.Well executed ruins, pieale the eye much more than the fan;i 
image of Tartarus, Olympus, or the ellariot of the fun; .an imag9 
a much inferior to that which we trace in ourfelves, as m chime: 
rical objg&s': it coPes nothlng to the mind to go.bey. ond poflbi:' 
lity, and .tO make to itfelf models of every imitation. ¾rotn 
thence it happens, that the marvellous, tho' mlfplaced in tragedyg 
is not fom the epic poems, where the maomaton, always m- 
duPcrious and magnificent, is charged witl the execution, and 
idraws from it quite a different part than that which the beR ma.-. 
.chinit can form ,on our theart% or the fplendor of the mof po- 
tent monarch.' 
Tho' mufic, taken as an art of imitation, has Rill more con- 
re&ion vith poetry than painting, that, in the manner it is ufed 
.on the Rage, is npt fo fubje as poetry to form with the mufie 
; double reprefentation of the fame obje&; becaufe the one ren- 
ders the fentiments of mankind  and the other the image only of 
the place wherein they are fixed: an image which fre. ngthens the 
illufion, and tranfports the fpe&ator to every part wherein the 
&or is fupp9fed to b.e placed. But this removal from one place 
to another, ought .to have rul. a/d boundaries: It is not per- 
.mitte, d in regard to .tlfis; to ,call forth {he agility of the imag,- 
nation; but by confulting...the law of nature; and tho' the fpec- 
tator leeks 001y an attention to'thole fi&ions trom wilenee he 
draws his whole pl'eafure, we muf riot abut his credulity tb far 
as tb make him aihan{d of'it." In 'a' word we mupc remember 
that we fpeak 'to' fenfible heart.s, 5¾ithout forgetting that we ad- 
drels ourlhlvs to reafolaab. le people. Not that  wo.uld tranfmit

' It is th6n wlth reafon that p the changes oF the œcene are left to 
lbfiic from a to aft; and For their being regular and adlniflible 
it is ftifffejent tha.t they can naturally go from the place whenc 
liey go out, to the place whereto they pals, in the interval of 
'ime which pail'es, or'which [he aftion ¾uppoFes betreen the two 
ffts; fo that, as the unity of time ought to be coni:ined' nearl 
'Vithn the duration of twenty-four hours, the unity of place 
rhould be confined nearly within the fpace of a day's journey. 
In regard to the changes of the fcene, praifed rometimes in the 
frame a, they appear to me equally contrary to illufion and rea- 
:ibn, and ought 'to be entirel)t atotifled fi'om the theatre. 
Here then is the method by which the concurrence of the 
couftic and perfpecøtive may improve the illtifion; flatter the 
fenties b dfferent but analogous impreffions; and convey to the 
foul the fame intereft with a double plealure. Wherefore it would 
'be a great error to imagine, that the regulation of the theatre has 
othing in common witlx that of mufic,. if it was only from the 
.general agreement which they draw from the poem. 'Tis for 
,lie imagination of the two artiris' to determine together, what 
that of the poet has left to their difpofal; and to agree tb well in 
that, that the fpeator may always feel the perfe& concord of 
ß vhat'he fees and what he hears. But it muff be conferred, that 
he ta/k of the mufician is the greateft'.' 'The imitation of paint- 
;ing is always cold, becaufe it wants that fucceflion of ideas and 
impreffions Which inflames he foul by degrees, and every thing is 
,œaid at the"firft view. The imitti've powers of that art, with 
t:veral appareni objes, are conffined in effecVt to very weak re- 
pretkntation. It is one of th'e great adx, antages of the mufician 
.t.o be able to paint ilfings which z:annot he hearct; Whilfl: it is im- 
pofffbte for the painter to paikt t'hotb which cannot be/ben: and 
'the g.reat.eft prodigy of an art vhiclt has aivity by its move- 
inents only is to be able to form them as far as the repre'fentation 
of repotb. Sleep, the cahn of night, flitude and filerice tllem-

Of the mufician., the tkilful muffclan will not leave the works o' 
the painter without fom' profit. [fie will' not only agitate the

There was a time when he French overtures-ferved as a model 
for all Europe. Mot fix. ty years. ago, they tnt from F'ranc½ 
overtures, to place at the head of their operas in Italy. I have 
even feen many ancient Italian operas marked.with an overture 
of Lulty at their headl This is what the Italians at pretnt 
contradi&, finee the whole has-had fuch a change; but, never- 
thelefs, the fa& is very certain. 
The inff:rumental mufic having had an aff:onif'ning progrefs 
within about trty years, the ancient overtures, m,.ade lot the 
fvmphoniff:s, who were little tkitled in managi'ng their inff:ruments 
were very loon 'left for the French; and they have been con- 
tented with nearly preferring their ditaofition, The Italians 
themtlves have not been flow in fecuring themlIves from this 
hindrance; and they at prefent dietribute their overtures in ano- 
ther manner. They began by a lively and pleating piece of two 
or four times; then they give an andante  Denaijeu, in hich 
they aim at dilllaying all the graces of a fine mufie i and they 
finlib by a brilliant-allegro, generally of three times, 
The reatbn they give for tills diff:ribution, is, that in a nume- 
rous te&acle where the fpe&atocs make great noire, 'they lhould 
pertade them to itenee at the firf tt. ro!e, and fix their attention 
by tbme bold beginning which may tlrike them. They thy, that 
tle grave of our overtures ia neither heard, or lillened to, hy any 
one; and that our firff ffroke of the fiddle-flick, which we boa

$nent$ which prgccd<s it and with which it is contiaunded, is

.- .They add, that after having rendered the fpeator attentlve 
at a neceffary that he ould be intercried with lefs noife by an 
aeeable and flattering air which may ditofe him to the ten- 
derhers with which he is o be infplred; and lafily to put an 
end to the overture in another charaer whiclb being conneed 
with the beginni ot the drama denote% by finiing with ec/ats 
the filenee which the aorv at hi entrance on the flag% require 
of the fpeators. 
Our old courfe of overruns  eaufed a plffant idea to be 
circulated in France r any have imagined that there was fucl 
an agreement between the form  Lully's overtures and every 
opera that it could not be chaned without fpoiling the rife& of 
the Whole; fo that oq the beging of a fymay which oul 
be in a different taR% tuch foe inanc% as an I'talian overture 
they woId ty with eontem that it w a fat% and not a 
overrut% as if every overture' was n a fata.. 
I know very well, that it would be a d'efirable thing for a pro- 
Per and fenle cohesion to be twee the charaer of a 
overtur% and that of the wo which  int'oduces; but inea 
of laying that all o,eures ould be ca in the time mould, thi, 
lays precifely t eomrary. Betide%  ou muians fail f 
often in eatchi the'true nneion' of the mufic m the vords 
in each pict% how n they caxeh the fiev and more remote con- 
eions between he ordonnance of an overmr% a that of th

lves to have caught there connerions. by coHeing, before-han 
in the overrut% all the charers expreffed in the pict% as if 
they would expref, the fame aion twit% d that what is to

ood o,ertur%  that whicg difpoths the heart of the fpe&ator 
in fuch a manner as that it opens naturally to the intere which

Ths is the real effe that a good overture mu produco. Thiu 
is the plan. on which it muff be direred. 
OXIPCNI. Is the name which the ancients gae, in the

PAPER RULED. By this name is called the paper prepared 
with the ttaves entirely drawn to mark the mufic thereon. 
(Vide Stave,) 
There is rut'd paper of two klnds viz. that whole length 
ceeds its breadths' fuch as is commonly nfed in Franc.e'; and that 
whole breadth is greater than its length. This laft is the only' 
one ufed in Italy.- However by a wlxim the teafen of which 
know not, the roper-makers of' Paris call taper rul'd a la Rran- 
0/, that which is ufed in Italy; arid Paper ruffd a l'Italienne 
that which is preferred in France. 
The form whole breadth exceeds its length appears m0t com- 
modious in my opini6n, either becaufe a book of this form is 
better laid open on a delk'or becaufe the ftaves being longer, 
they are left frequently changed: Mor'over it is in the changes 
that muffclans are 'rubjeSt to take one flare for another i particu- 
larly in partitions. (Vide Partition.) 
The ruled paper utd in Italy, has always ten flares, neither 
more or lefs; and that mahes ex. aOly two lines or columns in the 
ordinary partitions where we have always live parts, viz. two 
trebles of vlolins the Viola the tinging part, and he bari. The 
divifion being always the tme and each one finding, in the par- 
itions, his part placed in like. manner paffes always from one 
column to aftother without embarraflinent or fear of miI'taking. 
But in the French partitions, where the nmber of Flares is .not 
tixed and determirred, either in the pages or columns we are 
ways obliged to hefttale at the end of 'each ttave, to' find, in 
e'olmrt that fol, lows, the fia, ve coetondern to' that wherein we 
are, which renders the muffclan m'o½ doubtful, and the execution 
more fubje& to a failure. 
D d d a PARADIAZEUXIS. 
PARADIAZEUXtS. Was, in the Greek mufic, by the tradi- 
tion of old Bacchius, the interval of one tone only between the 
chords of two tetrachords; and fuch is the nature of the dill. 
jun&ion which aOs between the tetrachord lynneinchon, and tb.e 
tetrachord diazeugmenon. (Vide there words.) 
PAR AMESIS. This was, in the Greek muff6, the name of 
the firec chord of the tetrachord dlazeugmenon. We muec re- 
member, that the third tetrachord may be conjoined with the 
fecond; then its flrec chord was the reeds, or the fourth chord 
of the fecond; that is, this reeds was common to the two. 
But when this third tetrachord was disjoint, it began by the 
chord called paramefls, which, inetcad of being confounded with 
tile reeds, was placed a tone higher; and this tone formed the 
diuncion or diecanoe between the fourth chord, or the thatpod: 
of the tetrachord metbn; and the firec or fharpeflr of the tetra- 
chord diazeugmenon. 
Paramefis fignifies near to nefis; beemule, in 'effe&, the para- 
me{is was only a tone diecant, the' there was tbmetimes a chord 
between two. (Vide Trite.) 
PARANETE. Was, in ancient mufic, the name given, By fe- 
veral authors, to the third chord of each of the three tetrachords 
fynnemenon, diazeugmenon, and hyperboleon; a chord which 
œome diecinguithed only by the name of the genus wherein theft: 
tetrachords were ufed. So the third chord of the tetrachord hy- 
perboleon, which is called hyperboleon dlatonos by Ariecoxenes 
and Alvpius, is called paranete hyperboleon, by Euclid.' 
ß PARAPHONY. Is, in ancient muiic, that kind of confo- 
nancc which does not relhlt fi'om the lm½ founds as the unilbn, 
wilich is called homophony; nor d-ore the replique of th fame 
founds as tile oc"tave, which is called antiphony; but founds really 
different, as the fifth and fourth, the only paraphonies' admitted 
in this mufic: for, as to the tixth and third the Greeks did not 
p/ace them 'ir the rargk of paraphonies not .e.ve.n adr0ittlng them

PRHYPATE,

and the parhyp'ae nefori. This word parhypate gnifid-s œub-

PARODY. An air of fymph0ny, .of which a tinging air 
;onned by adjufting 'he words. In rnuflc, well-compofed the ai: 
is macle on th words; and in the prody the words are made oa 
the air: _A_H the coupk s of a /'ong, except the firft are kinds o 
parodies; and this is, in general, what is felt too muh by 
inethod of murdering the l:-Ot-ody, (Vide Song.) 
P2kP, T. This is the name of' every voice or feparated iielody' 
whoœe re-union forms the concert. To conilitute a cocord 
founds mull be heard at a time, at leaft which a tingle v0ic& 
t:annot do. To form, in 1ingin, a harmony or a colletfen 
concords, many voices are necett'ary. The air which belongs to 
each of there voices is called part  and the c01Ieion of all th 
pars of a tame work written bel'ow each othm' i called parti- 
tion-. (Vide Partition.) 
As a complete concord is cornpored of four founds, there ar 
all'o, in muff% four principal part%- the tharpeil of which is called 
treble, and is lung by the voices of women, children, or mufici: 
The other three are the counter tenor the tenor 
which atI belong to the voices of men. 
Extent Of the {'our Vocal Part, 
Treble Counter Tenor, Tenor. Balb. 
We may here t'ee the extent of the voice irl each oœ tleF 
parts, and the cleft which belongs to it'. The White notes fhow 
the full found% where each part may reach to an equal lielght: 
and an equal dercent; and the demi-crotchets which follow fho 
tile founds wilere the voice begins to be forcekl,' and which 
Ought to form in palltuff only. The Italian voices aimoil always 
exceed this extent in alendrg prticularly the trebles  but th 
voice becomes then a kind ofyeucet and whatever art it ma' 
tli: 'to ½liuil it, 'it is 'certainly tb. 
Some one, or each of there parts, is rub-divided, when. we 
½ompoœe with more than four parts. (Vide Treble, Tenor, 
In the firPc invention of the counter-point, there were at 'firf 
Bnly two parts; one of which was called tenor, and the other 
dif{/ant. Laftly, a thh'd was added which had the name of trip- 
]urn; and a fourth, fometlmes called quadruplum, but more com- 
monly motterns. TheiS parts were Confounded very frequently 
one with the other: Tis but by little and little, that, extending 
themtlves to /harp and fiat, they have taker b with the moil: 
feparated and mope fixed diapafons thole names which they have' 
at prefint. 
There are alfo inf[rumental parts. There are even inru- 
merits, as the organ, the harpfihhord, the viol, which may form 
fevral parts at a time. We divide aIœo the inffrumental muf½ 
in four parts, which anfwer to thole of the vocaI muflc and are 
called treble, fifth, tenor, and bars; but the treble is generally 
Jkparated into two, and the fifth is united with the tenor a under 
the common naae of viol. 
F. xtent of the four InPcrumental Parts, 
Treble of the Violin. Tenor. Viola or Fifth. Bafs. 
We here find tile clews and extent of the four inflrumentat 
arts; but we muff take notice, that the generality of inrumenta 
ave not precit bounds above, and that they may be ex- 
tended as far as .poflble, at the expence of the ears of the audi- 
ence; whereas; m the lower parts they have a fixed term which 
they cannot pals. This term is on the note which I have 
marked; but I have marked above only that which we ma$ 
a'each without loolknng. 
There are parts vhich ought to be lung by one voice aIone or 
played by a tingle inffrmnent; and thot are called reciting parts. 
Otlzer parts are executed by feveral perlbns tinging, or playing ia 
tiniron; and are called concertant parts, or parts of chorus.' 
We call a/lb part tlxe paper of mufic tin which is written the 
feparated part of each muffclan. Sometimes tkveral ting or pla$ 
a tlo fame paper; but when each haa his own 'aa is the general 
pra&ic½ 
ira&iee in great plece of mufic, then, tho  in this fenfe eaclz 
concertant has his part, it cannot be laid, in' the other tinfe, 
that there are fo many parts of concertants.whilfi the fame part 
is often doubled, trebled, and multiplied m proportion to the 
total number of executants. 
laAP,.TITION. A colleellon of all the parts in a piece of 
muff% where we fee, by the re-union of the correfponding fiaves, 
the harmony which the)' form together. ' We write, for this 
pu. r. pof. e, all. the parts froin cave to ftave, the one below the other, 
with the cleft fuitable to each, beginning by the fharpefi, and 
lacin the bars below all We arrange them, as ! have laid at 
the word Coper, fo that each meafure of a cave be perpendicu- 
larly placed above or below the correfpondent meafure of other 
parts, and enclofed within the fame bars prolonged from one to 
another, fo that we may fee, at firf fight, all hat fhould be 
derftood at a time. 
As in this difpofitlon, one tingle llne of muf': comprehends a 
many ftaves as there are parts, we confine all there fiaves by a 
ttroke of the pen which is called column, and wb. ieh is drawn 
on the margin at the beginning of the line thus cornpored; then 
we re~begin by a new line, to trace a new column, which i$ 
filled with the remainder of the fame ttaves written in the fame 
order. 
$% when we wlfb_ to ollow a part, after having gone thr6' ho 
Crave to the end, we do not pals to that which is immediately be- 
low, but we examine what rank the ave that we quit holds in 
the column; we leek in the column which follows the corref- 
laondent part and we find therein the continuance of the œame 
part. 
The ufe of partltion is indlfpenfable for compofitlon. 
lie alfo who conducts a concert, mutt have the partition under 
his eye, to fee if each one follows his part, and to replace thole 
who are in error. It is even ufeful. to the accompanilt to follow 
the harmony truly; but in regard to other muficians, we give 
generally his feparate part to each it being ufelefs for him to lke 
that whic.h he does' not execute. 
There .at% howevers rome cafes where we join, in.. a feparat  
laart other parts in timilar partitions, for the con,emenee of the 
executants. Firit, in vocat parts we generally note the thorough 
bali in partition with each reciting part) either to prevent the 
finger from the trouhlb of reekrasing his paufes in following the 
batik, or that he may himfelf accompany in repeating or' re/:itin 
1i part. econdly, the two parts of a tinging duet. are marked

before the dlalogue under.hls eye s may better enter Jnto the 
tit of it, and accord more eafily with its counter-part. Thirdlya 
in the'in/rumental parts, we are cautious, in confined recitatives, 
to mark always the tinging part in partition with that of the 
inrument; fo that in tho alternatives of unmeafured airs and 
.meafured fymphony the fymphoni may take the time of the 
rittornels tue without heftrating or erring. 
PARTITION. Is alfo, among organ and harpflchord 
ers a rule for according the infirument, beginning by a chord 
or pipe of each touch in the extent of an oave or rathermor% 
taken near the middle of the keys; and on this o&ave or partition 
We accord all the re afterwards. This is the method we follo 
for the formation of a partition.

PASSACAILLE. A kind of ehacon, whol'e air is more ten- 
der and the movement flower than in the ordinary ones. (Vide 
Chacon.) 
The paffacaillc's of Armeda and Ira arc celebrated in the 
French opera. 
PASSAGE. An ornament by which a fireke of mufic is or- 
namented, in general rather fhort, which is cornpored of feveral 
notes or diminutions, which are lung or played very lightly. 
'This is what the Italians call alfo pa. ffo. But every finger 
Italy is obliged to underiland the competition of the paffi, 
whereas the generality of French fingers never remove from the 
note% and form only there paffages which are written for them. 
PASSg PIED. The air of a dance of the fame name, veQr

pens, that the French think every thing pathetic that is 
and that all flould be flow that is pathetic. They even have airs 
which .become gay and trifling, or tender and pathetic, according 
as they are lung quick or flow. Such is an air fo celebrated in 
aristo which the Hrff charaer islE[yen on there words,  II

diufe.--Fiet a%,is, & cnm voler aror. 
But the talian mufic has not the fame advantage: Eac atr, 
each melody has its charaer fo appropriated, that it cannot b 
deprived of it. Its pathetic of accent and melody is felt 
every kind of meafure and even in the moff tively ovements. 
The rench airs change their charaers as the movement 
ped or flackcued. Each Italian air has its movement fo de- 
armined, that it cannot be changed without overthrowing the 
melody. The air, thus disSEared, does not change it scharaer 
it Ioihs it: It is no longer an air; it is nothing in the eharaer 
o the moveznt, neither can it be in the genus, n the mode, 
or in the harmony; fince there are pieces eually pathetic in the 
three genera, in the two modes, and all imaginable harmony. 
The true athetic is in the aonate accents which is not dercr- 
mined by rules; bt which the genus finds, and the heart feels, 
wlthour the art being able to give its laws ]n any refpes. 
PAVANE. The air of an ancient dance of the fame name, 
which ha not been in ufe for ronge time. This name of pavan

, g 
other, a kind of tail after the manner of tlw peacock's. Th

nd'tis in allufion to the vanity of this attitude that they haw 
formed the reciprocal verbpavan0r. 
PAUSE. An interval of time, which in the executlon ought 
to pals in filerice by the part wherz the paut is marked. (Vide 
Silence.) 
The name of paufe may bo applied to filerices of different 
rations, but it is underttood of a full meafure. This paufe 
marked by a demi-bton, which, leaving one of the interior linca 
of the avc detk'eds as fhr as tlxe half of the ace comprifed 
between this line and the Iine immcdiate[y below. When 
have tbveval pauls to mark. we fiould then marc ufo of figures, 
whid I have fpokcn of at the word R¾t. ' 
In regarcI to the demi-paufe, which is equal to a minum or 
the half of a four-ti'med meafure, i't is marked as the entire' 
paufe, and with this difference, that tb.e paufe belongs to a line 
above, and that the demi-paufe is below. 
We mugr take notice, thaw the paufe i' always equ'al to a 
i-neafure, in whatever kind of meafure it may be,, whereas the, 
deni-pauœe has a fixed and invari'able power; fo that, in every' 
m.eafure, which is fuperior or inferior' to- a femi-breve, or tw 
re,hums, we ought not to ufe the demipaufe to mark a demi- 
meafure, but other filerices which exprefs its iu-/t powers. 
In regard to the other kind of panres known' in our ancient 
mufic, under the name of uJblefi paufis, becaufe they were' placed 
after the cleft, and which ferved not to expref filences, but to' 
determine the modes; this name of paufes was given them only 
thro' error'; for which resfort I tranfinit the reader to the 
Reft and Mode, on that article. 
TO PAUSE. To prefs on a fyllable in tinging: Wa ought 
xot to paufe but on long fyllables,,and never on the e mute. 
PEAN. An air of vi&ory amongft the Greeks in honour of 
the gods, and particularly of Apollo. 
.PENTACHORD. Was, amongft the Greeks, rometimes art 
i.nftrumerit of five chords, and rometimes an order or tftern 
formed of five founds. [t is in this left fenfe, that the fifth or 
diapente, was rometimes called pentachord. 
PENTATONON. Was, in ancient mufic, the name of an 
interval which we, at prefent, call' fuperfluous fixth. (Vide 
$ixt. h.) It is cornpored of four tones,.of a major femiotone, and 
a minor; from whence it. receives the name of pentat0non'.whiclx 
fignifies five tones. 
PERFECT. This word, in mufic, has feveral fenres. When 
joined to the word concord, it fignifies a concord'which compre- 
hends all the confonances without any diffonance. Vhen joined 
to cadcure, it. expreffes that Which bears the fenfible note, and the 
dominant falls on the final. Whe, joined to the word contbnances 
it e. xpreffes.a jut and determined interval, which can neither be 
major or minor; fo the oOav% the fifth, and' fourth, are perfecq:

' HIL2ELIA. 7ras a kind of hymn among-ff the Greeks, 
Ifong in honour of Apollo. (Vide Song.) 
PHONIC. The art of treating and combining the founds on 
the princip!es of the acouffic. (Vide Acouffic.) 
PHRASE. A continuance of an air or harmony, which forms, 
without interruption, a'fenfe more or lefs finifhet, and which 
'terminated on a ?top, by a cadence more or lefs perfeCt. 
There are two kinds of mufical phrafes. In melody the phrafe 
is conrtituted by'the air; that is, by a collection of founds fo 
'difpofed, whether in connection to the tone or movement, that 
they form the whole well united, which is refolved on an effen- 
tim chord of the mode in which we are. 
In harmony, th'e phrafe is a regular contlnuance of' coneordg 
all urnted to=ether by &ff'onances, expreffed or underflood, which 
is refolved 'on an abfolute cadence: according as the t}nfe is 
more or lefs'finifled, the Prop alfo is more or lefs perfeCt. 
It is in the invention of mufical phrafes, in their proportions, 
in their inter-mixture, that the real beauties of mufic confirm. 
A compotr, who punctuates and phrafes well, is a clever fel- 
low; a finger, who feels, marks well his phrafes and their ae- 
'cent, is a man of tae: but he who can only fee, and render 
the notes, the tones, times, and intervals, without entering into 
'the fenfe of the phrafes, however lure, however exaCt he may 
in-every other refFeet , he is no more than a fapfcull. 
PHR. YGIAN. The phrygian-mode is one of the four prln- 
:ipal and moec ancient modes of the (-reek mufic. Its charaCter ' 
xvas bold, lofty, impetuous, vehement, terrible: According to 
ahthenaus al!o, the trumpets, and other military inecruments, were 
founded on the phrygian mode. 
This mode, invented, they fay, by the Phrvulan Maxfyas, is 
'placed in the middle, between the lytian and do%ic, and its final 
is at a tone dietante from that of each, 
PIECE. A work in mufic of a certain extent, fometlmes of 
tlngle divifion, rometimes of feveral, forming a concinnity and 
totality, formed to be executed together. So, an overture is 
piece, tho' cornpored of three divifions; and an opera itfelf is fo, 
.l;ho' divided by arts. But, betides this g.eneral acceptation, the 
svord piece xvas allb a more peculiar one m inftrumental mutic, 
and only ior certain inttruments, fuch as the viol and harpfichord. 
For inttance, we do not fay, "A piece for the violin," but 
'*t .d./bata ;" and we never Ihy a fonata for the harpfichord, but 
a piece. 
PINCH. A kind of grace proper for certain in{trurnents and 
particialarly the harptlchord; it is formed by ftriking alt6rnatively 
F f œ he 
Big P L 
the fount; of the written note, with the Found .of the {nerio 
note, and obferving to I,cgin and finifl by the note which Ieav 
the pinch. There is this 2liferenee betwe'cn the i)incb and tril/, 
that the latter is ftruck with the fuperor noe, ahd the pinch 
with the inferior. So the trill on ut is ffruck on the ut anti 
re; and the pinch on the fame ut is ffruck on the ut anti ti. 'I'he 
pinch is marked, in the pieces of Couperin, with a finall crof. q, 
very timilar to that with which the trill is marked in ordlnai-y 
mufic. Vide the figns of the one and the other at the head of' 
that author's pieces. 
TO PINCH. Is to ufo the fingers, inftead of the bow to 
make the cho'ds of an inftrument found. Therc are chord in- 
t3rument, which have no bow, and vhich are played only by 
pinching, fuch as the lute, guittar, &c. but xve nifo fo'metine 
pinch thole where we generally ut the bow, as the violin and 
vlolincelIo; and this method of playing, altooff unknown in the 
French mutlc, is marked in the Italian by the vord pizzicato. 
PIZZICA'FO. This word, xw'itten in the Italian mufic, de- 
notes that we muff pinch. (Vide To Pinch.) 
PLAGAL. A plagal tone or mode. X'hen the oCtave is 
found arithmetically divided, according to the ordinary language 
that is, when the fourth is in flat, and the fifth in lharp, we thy 
that the tone is i)lagal, to diftmguith it fi-om the authentic where 
ihe fifth is in flat, and the fourth in fiarp. 
Let us ruepole the octave A a divided into two parts by the 
dominant E. If you modulate between thet two Ias, in the 
œpace of an oct'rave, and make your final on one of them, your 
mode is authentic. But if, modul:/ting. between thete two la's 
5, ou make your finaI on the 'dominant mb which is intermediary, 
or modulating from the dominant to its octave, you make tl½ 
final on the intermediary tonic, in there two cat:s the mode i 
placl/'e then is all the aliiTerence by which we fee that all the 
tones are really authentic, anti that the diffincCtlon is onl) in the 
diapatbnof the air, and iu the choice of the mte on which we 
ftop, which is always the tonic in the authentic, and oftenell the 
dominant in the plagal. 
The extent of the laws, and the divifion 6f the'parts, has made 
thel diPtinions dJfappear in mufic, and they are no longer 
tnown but in that of the church. We count therein four pl:gal 
or collateral terms vJz. the lcotd, fourth, fi.xth, and eiglnli 
all tholk: wholi number is equal. (Vide Tones of he Church.)

there peculiar term Iratriers on pedantry. The term to play be- 
cot=es eneral. and fuits lnlinfibly every kind of inrument. 
PLIQA. A kind of l}gature in our ancient mufic. The pllea 
was a fign of heftration, or ffoxvnefs, (Signurn morofitatis, a 
Im-is fays). It was made by paffing from one found to another 
from the tml-tone to the th, whether in atkending or falIing 
and there were four forts: Fir, The pliea,- long, and afcending 
is a quadrangular with a tingle afcendant ffroke to the right or 
ß 
with txvo rokes, one of which on the right is the greate 
Becondly, The long defeendlng pliea has two defcendant ffrokes, 
one of which on the right is the greater . Thirdly The 
ort afeendant plica has its roke arcending from the left, longer 
than that on *he rlgh . Fourthly, The defeendant has the 
roke detkending from the lett. gmate[ tha n that on the right  
POINT. This vord, in mufie, fignifies feverat different thin=s. 
There ar% in our anelent muff% fix forts of point% viz. Point 
of perle&ion, point of impeeion, pnt of inereafing point 
of dlvifion, poifit of tranfiation, and i'nt of alraton. 
I. The point of perle&ion belongs to the ternary dlvifion. It 
renders every noe perfe&, that is foliowe& by another not% lef 
'.by tlxe half of its figure; then by force of .the intermediary 
pbint, the precedent note is equal to the triple inead of the 
double of that which follows. 
I1. The point of imperfeion placed on the left of the Iongue, 
diminiflies its powers, fo,netimgs of a 5 or femi-breve, 
fi.nnetimes of two. In tlxe firR care, we p femi-breve be- 
tween the Iongue and the point; in the theond, we place two 
femi-breves at the s'ight of two longues. 
III. The point of increaring belongs to the binary divifion, 
and, between two equal notes, makes that lhperior which pre- 
cedes the double of thnt which follows. 
' IV. The point of divifion is placed before a femi-breve, fol- 
lowed by a breve in the perfe time. It takes away a time from 
this brev% and makes it equal only to two fetal-brews, inRead 
of three. 
'1/'. If a feml-brev% between two polnt, flouict be foJlowec 
by two or more breves in imperfe time, the fecond poin( tranf.- 
œers its fugnification to the lafl: of there breves, renders it perfcO- 
;and makes its powers three times. This is the point of tran- 
fiation. 
¾I. A point between two femi-breves, placed themfelves be- 
tween two breves or fquares in perfccøc time, takes a time front 
each of theœe breves, fo that each breve is only equal to two fcmi- 
breves infread of three. This is the point of alteration. 
This fame point before a femi-breve, 1301Iovcd by two other 
femi-breves, between two breves or fquares, doubles the powers 
Of the la of there fcmi-breves. 
As there ancient divifions of time into perfec and imperqc 
re no longer ufed in mufic, all there fignifications of the point 
which in reality are ¾ery confufed, have been long aolifie3. ' 
fit prefent, the pmnt taken as a power of the note, is alwaya 
equal to the half of that which precedes it. So, after the 
breve, the point is equal to a mlnum; after the m.inum, to a 
rotchet; after the otchet, to a demi-ctotchet &c. But this 
method of fixing the powers of a point is not certainly the be 
hat might be imagined and often caufos ufeicfs embarranents. 
ORGAN or STOP POINT.. Is a kind of point which 
lave fpoken of at the word couronne. It is in relation to that 
kind of point that we generally call rgan-p.01nts thot kinds 
uf, meafured or not mafured, written or not, and all thol 
armonic fucceons vhich pats on a fgle note of the bars 
vays prolonged. (Vide Cadenza.) 
When this fae point, furmounted by a couronn% is writte 
n the la not of an Mrs or a piece of mufic, it is then callcd 
final nt. 
Lal.y there is another kind of point alfo, called detached 
points, xvhich are placed immediately above or below the head of 
the notes: Sveral are generally placed together, and this 
hat the notes thu Fointed ould be mard by equal tones of 
the tongue, or bow bold ad detached. 
TO POINT. I by mms of the poin b to rcnder altcrna 
tively long and fiort, the collegion of notes naturally equal 
ruth, for inancq a a continuance of demi crotchets. To point 
them on the otc: we a a pgint after the tir[; a double demi- 
crotchet on the tcond; a point nftcr the third; then a double 
crotchet; and !b t)n. In this fun truer they kccp two by tw% the 
thmc powcr wlxich they had. befqrc; but tlus power is ncqually 
diltriblted betxc tl0 ttvo 4cmi-cratchts, lb that the lit or 
1ongu% hal three quarters, and the tcond or brcve, the other 
quarter. To point them in tim cxcutio% we pail them unc- 
P 0 z 
ual, accordlug to there fame proportions, tho' they fhould ever, 
e marked as equal. 
In the Italian muftc, all the demi-crotchets are always equal, 
,mleli they are marked as pointed. But in tee French muti6 we 
do not make the demi-crotchets exa&ly equal but in the four 
timed meafure. In all the reft they are always pointed a little, 
unlefs it be written" Equal demi-crotchets." 
POL¾CEPHALE. A fort of nome for the flutes; in honour 
of Apollo. 
The polycephale nome was invented, according to rome, by 
the feecud Phrygian Olympus, and, aceceding to other's, by 
Crates, a difciple of the fame Otympus. 
ß POLYMNASTIC. A name for flutes, invented, according 
to rome, by a woman named Polymnepte; and, according to 
.others, by PolymneRus, fon of Colophonian me. les. 
POSITION. A part of the Crave, where a note is placed to 
fix the degree of elevation of the found whiclx it reprefents. 
. The notes, in conne&ion with the lines, have only two different 
pofitlons, vlz. on a line, or in a fpace; and thete pofitions are 
always alternative when we move, or diatonically fo. It is next 
the place which the line or fpace fills, and in connexion with tke 
cleft', whicl determines the real pofition of the note in a general 
.key. 
We call alfo pofitlon in the meafure, that time which is marked 
in beating, in 1owering or fixing the hand, and which is gene- 
:rally called the ecroke. (Vide Thefts.) 
Lattly, we call pofttion, in the playing of fleeve-inptruments, 
the place where the hand is pIaced on the fieeve, according to 
the tone on which we pIay, When we have the hand at the 
height of the fieeve againPt the finger board, fo that the index is 
.ced at a tone of the chord 3, jour, it is the naturaI pofition. 
hen we 1oofen, we reckon tlae pofitions by diatonic degi'ees 
wtfich the hand is diPtant from on the finger board. 
POWER. OF THE NOTES. Betides the pofition of' the 
notes vhi:h marks its tone, they alI have tbme determined figure, 
which marks its duration on tinl% that i% w!fich determines the 
powers of the notes. 
The invention of this is attributed to Jean de Muris, about 
the year 33 o, for the Greck had no other pover of notes than 
the uantit of t11a'hlgs, vhich alone muec rove that they haJ 
q Y . . p 
no mufic purely nttrumgntal. However, p, Nlcrfcnne, who had 
read the works of Muris, affures us ttat he law nothing to con- 
firm that opinion; and ntyfelf, after having read the greateft: 
part, have not been more lucky than himfi:lf, /Ioreove[, the 
amination 0œ manufcripts,. in [le 'uurtcentlx at% whicl are in 
he French king's library, doe not perfoad us to judge tha th 
different figures of notes, which are oun therein, were of fo 
new an initution. LaXly, it is difficutt to be belleyed, that 
during three hundred years and more which havepaed between 
'Gui Aretin and Jeanne Murks, the mufic thould have been en- 
{irely deprived of the rhyme and meatEre, which are its fire and 
principalß heauty, 
'- However it may be, it is certaln that the different powers of 
tle notes are of very ancient inyention. I find, in the earlle 
times, five tbrts of fiures for them, witho0t reckoning the liga- 
ture and point. There five are the maximum, the Iongue, the' 
.brcve, the femi-breve, and mlnime. See Plate. A. Fig. I. 
All lb'eVe different notes are black in the manufcript of GuiI- 
Iaume de Machault; It is only fince the invention of painting, 
thattlxey have thought of making them white, and adding ne 
motes to diRingui the powers by the colour as well as the 
:figure. 
The notes, tho' figured the fame, had not always the fame 
'equality. Sometimes the maximum was equaI to two longues, 
or the Iongue to two breves; fometimes it was equal to three: 
this depended on the mode. (Vide Mode.) It was the three 
thing with the breve, 5n conneOion with the femi-breve, and this 
depended on the time. (Vide Time.). LaXly, it was timilar 
with tte femi-breve, in donneion with the minime, and this de- 
'pended on the prolation. (Vide Prolatlon.) 
There were then double longue, perfe 1ongue, iraperle& 
.Iønghe' perleO breve, changed brcve, najor femi-breve, and mi- 
nor tbmi-brcve: feven different powers, to which four figur 
'only anfver, without reckonin the maximum or minime, a not 
of more modern invention. (tde thelb different words.) Ther 
Were alfo tbveral mher methods of m,difying the differentpowem 
of there notes, by the point, the llgature, and pofition of tha 
tail. (Vide Ligature, Plies, Poin*.) . 
' The figures which were added in tbecontlnuanceofthefe fiv 
or fix firl}, were the crotchet, the demi-crotchet, the triple, and 
even quadruple demi-crotchet, which would make eleven figpre 
itt all; .but as lbrn as it was the cuom to tpa.-ate the mealur 
'by bars alI the figure of n.tes were abandoned whic were 
equal to feveral mealhres, as the tnaximmn, which equalled eight; 
the iongucequaI to fimr; and the hrevc to two. 
The lni-hreve, which equals an entire meathr% is the 1onge 
power of note remaining in ulh andon which all the powers of 
t} other notes have been determi.ed; and as the binary mea- 
furc which had palFed a long time for leli perfe& than the ter- 
nary, took laxly the trebl% and lhrvcd as the balk of all the 
other 
ther meaf'ures; t'o the rub-double divi{ion cartled it on the fub- 
t'riple, which had alfo paffed as tile mo perfen: rometimes the 
œemi-breve was not equal to three minums, but two only; tl½ 
rnlnum two crotchets; the crotchets two demi-crotchets; and fo 
on to the quadruple demi-crotchet; unle{i in the cafes of ex-,' 
:eption, where the ib-dlvliion has been preti:rved, and exprefi7ed 
by the cypher :3 placed above or below the notes. 
The ligatures were alfo abolithed at the fame time, at leaft in 
)egard to the changes which they produced in the power of tl 
otes. The tails, in whatever manner they are placed, had no 
more than a fixed fenfe, and always the fame; and latllv, tl½ 
"ilgnification of the point was alt¾ bounded by the half )f the 
note, which is immediately before it. Such is' the condition in 
whicl the figures of the notes have been placed, in regard to 
their powers, and where they aually are. 
The equivalent tllences are explained at the article

TO PRICK NOTES. ls to write mufic with eharaer 
aeinea for that putpole, and which ace called notes. (Vide 
Notes.) 
There is-, n the method of marking mufic, an elegance 
copy which contls lefs in the beauty of tle note, than in a cer- 
tain exa&nel to place all the tigns litably, and which render 
=fic thus mkc6 much caficr to execute; which has been 
plained at the word Copiff. 
PRIMA INTENZIONE. A technical Italian word, whlcz 
],as no correfpondent in 'rench, and whlclx wants non% fince the 
idea which this word exprefis is not known in the Frenelt 
n air a piece diotima ;nte,=iw, is that which is forened on 
thdden quite entir% and with all its parts in the mind of the 
compotr i as Pallas came completely armed fi'om the brain 
Jupiter. The pieces, di prima bitetziow, are thch uncommon 
cokes of genius, all whol ideas are tb narrowly united3 that 
they form, as it were, only one alone, and cannot be p'eCented to 
the mind without the other They ace timilar to thole long 
periods of Ciceco, tho' eIoquent, the tnfe of which thfpended 
during all their duration, is determined only at the Ia word 
and which contquently, have fo,-med only one tingle thought i 
the mind of the author. There are, in arts, inventions produced 
by fich efforts of genius, and all the cealbnings of which inti- 
mately united one with the other cannot be formed fuccetfivelv 
but are nccefihrily offered to the mind, all at the fame tim 
tince the fir, without the Ia would form no fenfe, Such i%

only ones which can canre ext-afics, delights, thole trantorts of' 
the foul which convey the hearer from himœelœ; we feel them 
we enter into them at a moment; connoiffeurs can never be de- 
ceived in them. At the end of one of there rublime pieces, ruv 
through one of theœe extempore airs. All whole phraœes have bcea 
cmapofed orle after the other, or are only one phrare changed 
into different tones and whol accompaniment is only a collecCtion 
made without labour, and with whatever tare this laft piece may' 
be compoœcd, if the remmnbrance of the othel--leaves you any 
attention to beffow on it, it will be only to be frozen, as it 
were and impatient for it. After an air di prima iatenzlon% 
every other mnfic lores its effect. 
P[OGRESSION. A continued proportion, prolonged beyonci 
three times. (¾i'de Proportionk) Tile continuances of equal 
intervals are all in progrcfiion, and it is in identifying the neigh- 
bouring tel'ms of different progreflions, that ve are able to 
7plete the diaton}c and chromati.c fcale, by means of the moditi 
cation. (¾ide Modification.) 
PROLATION. Is, in our arrcient mufic, a method of deter- 
/ninin the power of-femi-breve notes. on that of the breve, or 
of the'minimes on that of the remi-breve. Thi proladen was' 
marked after the cleff and rometimes after the fign of the morley 
by a circle or demi-circle, pu-nc"tuated or not punctuated, ac- 
corclin to the followin ruled. 
Conhderin the rub-mple dirtfinn always as the moi perfete 
the prolation was divided nto perfeEt and imperfect, and eacl 
into major os mnor, in the hme manner as for th mode. 
The perfect prolation was for the ternary mearure, and was, 
marked by a point in the circle when i' was major, that is, wher 
it denoted the connection of the breve to the mni-breve; or by 
a point in a demi-circle when it was minor, that is, xvhen it 
preffed the connection of the remi-beve with' the minime. See 
1;:ig, II, and Fig. IIl. Pkte I, 
ß The imperfec' prolation was for the binary meafur% and wa 
marked as the time by a tingle circle when m'ajor,. or by a denS, i- 
circle when minor. ,cc Fig. IV. and 'Fig. ¾'. P[ate I, 
$'ome other figns ha.vc beel finee added to the perfeEt prolationo.

to cxprcfs the power of thre temi-breve% for that of the brcv%,

and of the cypher  , to expref the lowers of hrce rainurns fo 
lte tk mi-breve, 
At prefent, all prolatlons are abolifimd. The rub-double di- 
vldon has gained the point over the rub-ternary; and we muft: 
have recourfe to exceptions and particular figns, to exp,'efs the 
divifion of any note into three Others that are equal. (Vide Power 
of the Notes.) 
We find, in the Academical Di&ionary, that proatlon figni- 
es trill. I have never heard, or read, any where elfe, that thi 
word had fuch a fcnfe. 
PROLOGUE. A kind of finallet opera, which predes the 
greater, announces it, and ferves a its intodu&ion. As the 
thk}e& of prologues is generally elevated, marvellous, magnifi- 
cent, and full of praifes, its mufic flould be brilliant, harmo- 
nious, and more tender than pathetic.' %-e ought not to8rain, 
in the prologue, the grand movements we would excite in the 
piece; and the muffclan mu, without being flat and tirerome 
in the delivery, ill know how to manage fo as m ew hhnfelf 
intereing and fre in the body of the work. This gradation 
is neither felt, or rendered by the generality of compofers, but 
it is itl neceffary, tho' difficult. The be way would be, not t 
be in want of it, and to fupprefs entirely the prologues which 
oply tire and hurry the fpe&ator, or injure the intere of the 
pmce, by employing the meods of intereRing before-hand. 
The French opera's are the only one% which have preferred 
prologues.: They, moreover, furor them only became hey dare 
not murmur again& the finefs which they contain 
TO PKOLONG A SOUND. Is, in finging to, ma.n.age th 
voice, fo that we may continue it a long te ithout taking 
breath. There are two methods of proling a found: the 
fir i in fuainlng it always equally, which is generally done o 
lenets, and laboured accompaniment; the feeGrid, in rengthening 
it, which is more ufed in paffages and trills. The fir method 
reqaires more junefs, and the Italians prefer it: the feeGrid ha 
more eclat,,and pleares the French more. 
POPERLY. To ting or play properly, is to execute the me- 
lody with the ornaments lhltable to it. This melody being no- 
thing by the force only of the founds, and having no chara&er 
by itlelf, takes on, only by. the affe&ed turnings given to it ia 
its execution. There turmngs, taught by the maRers of the 
tae in tinging, are what are called the graces of the French 
rimtic. (Vide Graces.) 
PKOPOKTION. An equality between two conne&ion. 
There are four klads of cnne&ion viz. the arithmctical geo- 
metrical harmoni% and counter-harmonic. We muff have the 
idea of thelE different proportions to undcrffand the calcalations 
wi wlfich authors have loaded the theory of mufic. 
O g g z Let 
P R 
Let there be four times or quantities, a, b, e, cl; if'' the 
ence of the fir term a to the fecond b, is equal to the differenco 
of the third e to the fourth d, there four terms are in arithme- 
tical proportion: fuch at% for insane% the following numbers 
If, inead of havin regard to the dierence, we cornpar* 
there term by the method of containing, or being contained 
if for insane% the fir a is to the fecond b, as the third c is to tho 
fourth d, the proportion is geometrical: fuch is that which thef* 
:four numbers form, 2, 4 8, t6. 
' In the fi example, the excels by whlch the fir term 2 
furpaWed by the fecond 4, is ; and the excels by which th 
third 8 is furpaWed by the fourth lo, is alfo 2: there four term 
are then in arithmetical proportion. 
In tho fecond exampl% the fi term  is the half of the 
cond ; and the third term 8 is alfo the ball of the fourth 6: 
there four terms ae then in geometrica 'proportion. 
A proportion whether aithmetlcal or geometrical, is called 
nverfe or reciprocal; when after having compared the fir term 
with the fecond we do not ompare he third with the fourth 
as in dire& proporrion but the fourth with. the thiM, and tho 
eonne&ion being thus taken, are fouud equal There four num 
Bers 2 , 8 6 are in reciprocat arithmetical proportion; and 
,he four , 4, 6 $, are in reciprocal geometrical proportion. 
Vhen in a dire& proportion, the fecond term, or confequeneo 
of the fir conne&ion is equal to the fir term or antecedent 
of tha fecond eoBneion thet two terms being equal. are taken 
for the Came, and written only once in,cad of twice. So 
this arithmeticat proportion, t 4 4, 6 in,cad of writing tho 
number  twic% we write it but one% and the proportion 
placed thus,  , 4, 6. 
In the lmo mannel,, in this geometrical proportion, , 4 :: 4 8 
inead of writing 4 wic% we write only one, in this manner 
When the confcquence of the fil- connexion ferves as 
tecedent to the tcond, and the proportion is placed in three 
imes, thi proportion is called thorough, becatlfe between the 
tond references which form it, there  o interruption found 
therein, when it i placd in four times. 
Thel three terms . 2 4, 6 ar tn thorough arithmetical 
proportion, ad thcIh other three  , 4 8, are in thorough ge- 
ometrical pi'OpOl'tio When a thorough proportion is prolongcd 
that i, when it has more tllal) [[99 Bles ov two equal refer- 
ces, it is called progreffion. 
So thclh four tcrm, a 4, 6, 8, form an arithmetieal progref, 
n a'l;ich ma 7 be lu'olongcd as ;$ul as we [>leaf% in adding 
t4qe difference to the Iac term; and there four terms, , 4, 8, 
form a geometrical progrefflon, which may be prolonged in the 
fame manner, as much as we pleafe, in doubling the laf term, 
or in general, by multiplying it by the quotient of the fecond 
term, divided by the firf, which quotient is called the expofi.tn 
of the connexion or progreflion. 
When three terms are fuch as the fir to the third, as the dif- 
{ererice of the fir to the fecond is to the difference of the fecon 
to the third, there three terms form a kind of proportion, called 
harmonic. Such are, for inance, there three numbers, 3, 4, 6; 
for as the fir 3 is the half of the third 6; in the fame manner the 
excels t of the fecond on the fir, is the half of the excels 2 of 
the third on the feeon& 
LaXly, when three terms are fucl b that the aifference of the 
fir to the fecond is in the difference of the fecond to the third, 
not as the fir is to the third, as in harmonic proportion, but, 
on the contrary, as the third is to the fir, then there three terms 
form together a kind of proportion., called counter harmonic pro- 
portion. So there three numbers, 3, 5, fi, are in counter har- 
monic proportion. 
Experience has ewn, that the connerions of three choMs 
founding the perfe& m4or concord third together, formed ben 
tween themfelves, the fort of proportion which, on that account, 
was calld harmonic; but this is a pure proprier of numbers, 
which has no nlty wth the founds, or with their effe, 
the auditire organ; fo the harmonic and counter harmonic pro- 
portion belong no more to the art than arithmetical proportion 
 the geometfical which are even of much greater utility. 
We mu always think, that the proprieties of abfiraaed quanti- 
ties are not proprieties ot founds; and not leek, in imitation 
of Pytha oreans, rome filly chimerical analo ies between thingg 
f dfferent nature.s which have Olily connerions of convention 
between them.

which .the Theoricians were divided in the Greek mufic: it 
took its name from Pythageras its chiet] as the other re& took 
its name from Arioxenes. 
The Pythagoreans fixed all the intervals, as well confonant 
as diffonant by the calculation  conne&ions. The Ariox- 
nians on he contrary fald that they appealed to the judgment 
f the ear. But, at bottom, their difpute was only a difpute

UADrUPLE DEMI CROTCHET. A note of 
cqua, to the fourth of a demi-crotchet, or tlie ßßhalf of 
dou le [temi-crotchet. Sixty-four quadruple demi-crotchets are 
ixeceffary for a four timed meaful'e; but a meafure is feldom 
filled, or even a time, with that kind of note'. (Vide Power 
of the Notes.) 
The quadruple demi-crotchet is almof always united with 
other notes of equal or different powera, and is tlaus figured: 
i,½nthefi;: f It takes its name from four trokes or l- 
ß , which it bears.- 
QUANTITY. This word, in mufic as well as in profody 
floes not fignify the number of notes or fyllables, but the relative 
duration whictx they ouzht to have. The.quantity lroduces the 
rhyme, as the accent pt%duces the intonation. Fr%m the rtxym½ 
tnd intonation refults the melody. (Vide Melody.') 
Q_UARREE or BREVE. A kind of note formed thus

but it is very tldoln ufed. 
QUARTER OF A MINIME REST. A power of filenee, 
which, in the Italian mutic, is figured thus, , in the Frenclx 
-; and which denotes, as its nalne expreffes, the fourth .part 
of a mlnime reft, that is, the equivalent of a double demi- 
crotchet. (Vide Minime Reft, Power of the Notes.) 
QUARTER OF A TONE. An interval introduced into 
theenharmonic genus, by Yiriftoxenes, and whole computation 
is fordato. (Vide Enharmonic, Scale, &c.) 
We have nelthcr in the ear, or in harmonic calculations, any' 
principle which can furnifh us the exa& interval of .the quarter 
of a tone; and when we conrider what geometrical ope,'ation 
are neceffary to determine it on the monochord, we are nearly 
tempted to thine& that we have, perhaps, never toned, and never  
fhall tone the qum'ter of a tone jut}, either by the vole% or any 
inftrument. 
The muffclans call 'al[o the quarter of  tone, the interval 
!fich from two notes at a tone from eacl other, is found be 2 
l',vecn the B flat of the fuperior and the diefiB of the inferlo,-, 
an interval which the modification caufes to vanlfh, but which 
the calculation may determine. 
This fourth of a tone is of txVo kinds, viz. tile major enhar- 
tnonic, in the conneaion of 576 to 65, which is the colnple.- 
ment 'of two femi-tones to the major tone; and the enharnlonl½ 
minor, in the computation of i5 to i28, which is tile comple- 
ment of the two fame femi-tones lninor with the minor tone. 
Q..UATUOR. This is the name given to pieces of vocal and 
inptrumental mutlc, which are Of four reciting parts. (Vide 
arts.) There are no true quatuors, or they are to no parpole,

becaufe, in every concord, tilere are only two parts, at tile moil:, 
which form an ail- and which the ear can diftinguif14 at tile talle

never to place any filling up in a quatuol-. 
Q_UINQ_UE. A name given to pieces 9f vocal and inttru- 
mental muff% which are of five reciting parts. Since there is 
no true quaruer, for a inuch better realbn, there is no veritable 
uinque., Each of there words, the' paffed from the Latin to

paced in the DiCtionary of the Academy, that the recitative 
thould he uttered diftine"tly: There are recitatives which fhoul/1

endfed, laxly, within folne unity  ex,preon, do not permit 
the compofer to be diant from ele priipal tone; and if 
wied to modulate ch in fo ort a' fpace, he would offer onl T 
murdered phrfes, without unlon. taffe or 1ody :' A fuk verT. 
common in the F'reh and Germa mufic. 
But in the recitative, where the expreons) the fentlments, 
ideas, vary every inant, we ought to make ufe of inoduatlon 
ually varied, which may reprefent, by their contextures, th 
fucceon, exweWed by the d'ifcourfe of the reckant. The in- 
flexions of the fpeaking voice are not bounded by muficl in- 
tervals. They are uncontrouled, and impoble to be determined. 
Not ,einv able' then to Hx them with a certain precifion, the' 
mufician,o follow the words, fioutd, at lea, imitate them au 
much as poble; and for the purpofe of conveying to the mind 
 the aience the idea of intervals anti accents, which cannot 
be expreWed in nes, he has couffe to tranfitlons which thp- 
fe them: If, for inance) the interval of the m4or or minor 
feini-tone is neffary, he will not mark them; he cannot: but 
he will give you the idea of them by the aance of an enhar- 
monic paffa. A motion of the bate is often fucient to chang: 
all the ideas, and to give the recitative teat accent and inflexion) 
which the a&or is unable to execute. 
In regard to what remains, a it is neceffary for the audlenc 
to be attentive to the recitative, and not the bars, which ought 
to forin its effe without being liened'to, it thence follows) 
that the bars flxould continue in the fame note as long as poble 
for it is in the moment that its note changes and it rikem 
another chord, that it is attended to. Thet% moment, being

L'Anno q.uatordecimo del Secoio prefente nel" dramma che 
reprefentava in Ancona, v'era fu'I principlo dell  Attoterzo 
riga di recitativo non accompagnato da altri ffromenti che dal[ 
baffo: per cui, tanto in noi profeffori, quanto negli afcoltanti, 
dertara una tale tanta co,mnozione di animo, che tntti fi guarda-' 
wano in faccia l'un l'altro, per la evidente mutazione di cotore' 
c. he fi faceva in ciafckeduno di noi. L'Eitetto non era di pianto. 
(mi recordo benifiimo the le parole erano di fdegno); ma di 
certo rigore e freddo nel fingue, che di fatto turbava l'animo. 
Tr. edeci VOile fi recito il dramma, e letup. re fegui l'.effet.o fiefro 
umverfahnente: di che era fegno palpabile il foretoo prevo fden-,

RECITATIVE 'ACCO,N/IP'ANIED. Is tlat to which, be-. 
fides the thorough bars, is added an accompaniment of violins. Thi 
accompaniment, which cannot by any means be fyllabic, toge- 
tiaer with the rapidity of the utterance, is generally formed of 
long notes ihftained on entire meafures; and we write, for this 
putpole, on all the parts of the fymphonr, the word foienuto 
chiefly in the baS, which, without that, would ttrike' only fiat: 
and detached itrokes t'each chang of the note, as in the ordi-. 
mary recitative; whereas we muff, in that care, prolong' and fur- 
rain the founds, the whole power  of tile notes. When the ae- 
compa'niment'is neafured, this obliges us to meafure the recita- 
tive, which then follows and accompanies in rome kind of ac- 
companiment. 
RECITATIVE MEASUR'D: There two words are contra- 
diory. ß Every, recitative,'wlereln we find any 0tlier meafure 
than that Of tile ve'fe% is no longer recitative. But an odinarr 
recitative is often cha. nged on a fudden in mufic, aiad takes from 
meaihre and melody, whatever is marked in w,'i6ng on the parta 
a tempo, or a battula. This contraff, this well'managed cha,ge, 
aProduces ihrprifing effe&s. In the courfe of a reckati.¾e, a tende 
nd plaintivr½fiekion takes the mufical accent, ,and is difplavccl 
inlantl}, I)y the fweeteR inflexions of the mufic; tticn, being 
in. the lame manact- by. foue otlter lirely-and"impetu0us reflexion, 
it is rou$1l, itcrrupted to take at a monen% ttic 91i61e utter:-' 
=ace o the worcls. The'e fhort and meaœu,-ed peccs, accora- 
panicd, in general, wth tlutcs and horns, at' not uncommon 
grand italian recitatives. 
The recitative is attb meafm'ed when the accompaniment with 
ivhich it is charged, being tuneœul arid meafured itœelf obliges the 
vecitant to conform his voice to it. It is lei titan a meatiereel 
recitative, than, as I ha.re tid above a recitative 'accompanying 
I/he accompani meat. 
RECITATJVœ CONFIN'D. Is that vhich, being int'ermixC 
wit rittornels ad frokes of tmphony, confines, as it were, the 
reelrant and orchePcra, one to,yards the other. tb titat they ou,-ht' 
to be attcnuve m a mutual degree. Tlmœe atternauve pafiage 
of rcitaxive and melody, clothed with all the eclat of the or- 
½hefra, are the moi zouching, molt ravififing, and mr>it energi½ 
larts of the modern mealare. The acefor agitated, traniortec} 
x'ith a pallion which does not fuffer him to go throngh his fpeech 
is interrupted breaks off' makes a fl:op, daring w[ficb time the 
{n'cheftra tea,ks for him; and thel, filences, thns fiHed aff'e the 
audience infinitely more than if t!e aor himfell' xq)oke all that 
the mufie makes them nnderftand. Thus far, the French mufic- 
/has not been abte to make aay' ufe of the confined recitative. 
They have endeavoured to give ibme idea ol: it in a fcene, 
.Down du l'711affe; and it appears that the public has found, thae 
:a fituation when lively and thus managed, became, m.uch. more 
icterefting. What would rmt the conhned recitative do in grantS, 
and pathetic fcenes, if ib great an acquifition can be drawr- from.

'REDOUBLED. We call a . y'. , 
redoubled interval e*er fimple  
interval carried in its oave.. So the thrtecnth compoted of . 
tixth and oOave, is 3 redoubled fixth; and the tifteentl b whicl 
is an oOrave addzd to the oOav% is a redoubled oaveo When 
nttead of aa oave, we add tvo the interval is triple; and2 
quadruple when three are added. 
Every interval utlot name paflks œeven in number, is alvay 
at leait redotbled. To find the timpie of any redoubled interval, 
throw out revert as often as you can lrm. n the name of titis ia- . 
tcrval and the remainder will be the name of the timpie inter- 
a'!. From thirteen throw out fi2vcn tit remains; tb the thir- 
teenth is a redcuibled fixtlt. From fifteen take away twice fcven 
or ibm-teen, oi«e rcgla. ills i lb tim tiftntl is a tripled unilbsl 
 doubled uaavc. cclprocailt 
Recprocallv, to redouble nny timpie interval, add to it iven , 
md you will have the name of the fhme redoubled interval, 
triple a timpie ntervat, add to it fourteen. (Vide Interval';') 
lMDUCTION. A collco of noes diatonically deœcendlng-J 
'The term, as welt as its contrary ded'ucior, is ne longer uf 
but in church-muic. 
RELATION. _8 ½onnef'tion which he two founds that fortin 
an interva! have with one another, confidered by the genus of tha 
interval. The relation is ju when the. interval is jui, major or 
minor: it is fall% whetlzor fuperfluous or diminifhed. (Vide 
I4terval.) 
Amongt falfe!.'relations, we conrider as fuch in haxmony, thole 
only xvholk.twe founds cannot enter into the ihme mode. So'the- 
t.riton, which in melody is a fali relation, is not fo in harmon3r 
but when one' of the ibunds which form it is a chcrrd unknowrr 
to the mode. The dimlniflied fourth tho' banifhed from har- 
naony, is not always a fatfe relation. The diminifhed and fu- 
perfluous oc"taves, being not only intervals bahJilted from har- 
mony, but alfo impraicable in the mode, are lways fal-fe rela- 
tions. It is the fame thing with the r3i.minifled and fnlrfluoua 
thirds anti fixths, tho' the la5 be admitted at profont. 
in former times falfe relations were forbidden; at profen.to 
they are almot all permitted i melody, but not in harmony. 
'e may, however, make them ndergood provided that one of 
te two founds, vhich form a falfe relation, be not admitted 
a note of taft% and not as the conttitti. ve part of the concord. 
We call alfo enharmonic relation, between two chords which 
e at a tone of interval, the conne6tion which is found between 
the diefls of the inferior and that of the fuperi. or. tt is by th 
modifieation the lhme touch on the organ and harpfchord; but 
in rigour, it is not the fame ibund, and there is between them 
eharmonic interval. (Vide Enharmon:c.) 
R. EMISS. Retail; founds are thoi which have little firength,' 
t]ol which being very flat, cannot be rendered but by very  
1ooœe chord% or heard very near. 1Kernils is oppoid to intenh;

ttificaton in the movement of a fame rhyme, which had no other 
ounds than thole above or below which the ear was not of aa 
extent to perceive their proportions. 
The rhyme, in reference to the feet which entered into poetr7 
was divided into thre other genera. The timpie, which admitted 
only one kind of feet; h cornpored, which refulted from two 
r more kinds of feet; and the mixt which might be refolved 
nro two or more rhymes, equal or unequal, according to 
different combinations of which ir is fufcptible. 
Another fource o variety in the rhyme was the dierenc 
the movements or fuccffions of this fame rhyme according to the 
inter-mixture of the different vetres. The rhyme might be al- 
ways uniform; that is be ruck by two times always equal 
in the hexameter pentamerer adonian and anapeic refits, 
or always unequal, as in the pure iambic verfes; or diverfified 
that is mixed witl equal and unequal feet as in the fazons 
choriamBics, &c. Bur in all thet cat, s, the rhymes even timilar 
or equal, might, as I have fald, be very different in quicnsl, 
according to the nature of the feet. So of two rhymes of the 
fame genus, rethlting one from two fpondees, the other from two 
pyrrhics. tlie fir would be double to the other ia duration. 
.- Silences were alfo found in the ancient rhyme, not in truth[ a 
ours to make only rome one of the parts be filent or to 
g 
certain charaers to the mufic but only to fill the meafure o 
there verte, called catale&ics, which wanted a fyllab; fo 
filenc never cgld be found br at the end of the erfe to fupp17 
that fy!lable. 
In regard to Lene's they knew them without douBt fince the 7 
had a word to expref them. Its pra&ic% however, nm have 
been very Uncommon among them; ar la this may be 
lrred by the nature of their rhyme wMch was only the ex- 
effion o the harmony, and of the harmony of the veres. 
either does it appear that they pra&ifed trills and fyncops, or 
the points unlefs the inruments formed romething timilar 
accompanying the voice of which we have no 
offias in hs book De Poemature Cantis & Veribus', ralfea 
the ancient rhyme greatl  and attributes to it all the torce 
7 
the ancient mufic. He fay that a rhyme detached as ours 
which reprefents no hnage of things, can have no effe& and that 
the ancient poetic numbers had been invented only for the very 
end that we negle. He adds, that language and modern poetry 
are little fuitaBle ra mufic; and that we t}all never have ood 
'vocal mufic till we make crft:s avourable to the air; that is 
till we confine our !angaag% and give it, after the example o[ the 
ancients, the quaarity and meatbred eet b for

R H 
Our vetres, fays he, are precifely as if they had only one 
foot; fo that we have no veritable rhyme in our poetry: and/ 
in fabricating our verfes. we only take care to introduce a certai 
number of fyllabtes, without fcarcely taking notice of what nature 
they are. Surely this is not a fit compofition for muc. 
The rhyme is an effcntial part of mufic, .and particularly 
the imitative. The melody is nothi,g witbott it; and by itfelf 
it isfothlng, zs wc find by the effe of drums. But whence 
comes the i'mpreffion which the meafure and cadence occafion 
us What is the principl'e by which th'efc returns, fometime

The grand Italian airs, and all our arietta's, are in rondeau, a.

The qutJnes are magazines of a contrary fenfe, for thole wh9

Wo' vich are proper to them. It is ridiculous to place a 
complete hought in rondeau, divided into two branches. It 
xidiculo. us. t0 put in rondeau a comparifon, whole application 
ade oly n the fecond branch, in re-taking the fir, and finiflx- 
'ing by it.' 'L21y'i it is ridiculous to place in rondeau a general 
Jlought limited by an exception, relaiv e to the condition of him 
ho fpeaks; f0. that, forgetting the exception which has referenco 
to himfell, he may [ni in re-takiog thegeneral thought. 
' But every time. that a fentiment expxeff4d in the fir2 branch, 
'brings with it a reflexion wch 'enforces it, and places it in the

It is hwever unlucky, that a formula, defined to the 
tSee of elementary ules m harmohy, flould contiin a fault again 
there fame rules. It is to give early 'inru&ions to beginner t 
franrefs the laws tha are given them. This fault is in the ac- 
companiment of the xth note, vlth which the concord cyphere8 
by a 6, offends again the rules; for we can find no union; 
the fundamental bali defcends diatonically from a perfe& con* 
Cord on another p?r-fe&.concord. A liberty to be formed int 
 eule. 
We might manage that there Could be an union, by adding 
venth to the pe?fe& concord of the dominant; but then thim 
feventh, becoming an ave on the following now would not 
preferred 3 and the fundamental bars, deftending on a perfe 
concord ditonilly, after a conem'd of feventh, would make 
'movement quite intolerable. 
We mht ultb give to' this fixth not% the concord of finallee 
xth, the fourth of which would fomn an tinion; but this would 
be fundamentally a concord of teventh with minor third, wheg 
the diffonaneu thould not b prepared which i alfo againR tlt 
rules. (Vide To Pre(are.) 
We might eypher fixth fourth on this xth note, and it would 
be then the perl& concord of the theend; but I am in doubt 
lhg mtcian would approV ß variatio lh I underRb0d a* that 
avarlatlon which the ear does not adopt, an8 on a coneor8 wlic 
ternoyes too much the idea of the winelpal modulation. 
'We.might change the concord of the dominan% giving it 
'fiith fourih in,earl-of ihe feventh and then the timpie fix 
would fuit very well on the 'fixth .note which follows; but the 
fAh fouah'would fuit very ill on the dominan% unlefs it wa

from e theetic'eombinations reje&ed by the ear; and each 
mote, particularly t nanq ohld convey to it its proper 
cOneord.whev it has one. 
I look on it'then as a eertn firing'that Our rules are bad, or 
ß lhat the eod of xth with which xve accompany the fixth 
mote in afeending is a fault that 'ould be eor:&ed; and that 
ß O accompany this note rlarly, as .is neeary in a formula,

megle&ed to give one to the feventh; which in Fraoce has fince

the other european .nations. 
Wo mu not think that the conne&ions of the tones and 
tones, of which the fcale is cornholed. are thins nutely arbitrar

onf. Salmon relates, in his Philofophicl Traufaious tha 
e made, before the Royal Society, a tryal of this' fcale on chords 
exa&ly divided according to thefe pr6portiona, and that 
ere rfe&ly in nrd with the other inRmmcnts touch b

Monf. Malcolm adds, that having calculated and compg& 
there nne&ioas he found a greater number of 'faults in this 
fcale than in the precedent; but that the eors werg conderabl' 
fs, which makes fe compenfafion. 
LaRly, the other femi-tonic fcal is that of the Arixeniana 
hich P. eenne has. ve largely treated, and which M. R 
eau has eeavoured.to renew in there luff times. It con 
in metrically dividing the o&ave by eleven meths pror- 
ioned in twelve fetal-tones perfe&ly equ'al. As the conne&io 
are not rational, I will not give here tofe references which can- 
mot  expreffed but by the formula itfelf- or by logarithms off 
ß he terms of progreon between'the cxtrem  and a. 
odication.) 
As in the diatonic and chromatic genus the haaniRs.add 
third, viz. the enharmonic, this thiFd genus ould have its fcala 
alfo at leaff by thppofition; for tho' the truly enharmonlc in- 
ervals do not exiff in our keys, it is yet certain, tha every 
harmonic puffage fuppotss them; and that the mind, corre&ing 
the fenration of the ear on this point, paffes then' from one idea 
o another, onl through favour of this interval undeood.

every tone was exa&ly compoted of two minor femi-tones, ever 
nharmomc .interval would be null and this genus'could 
loger exi. But as a minor tone. itfelf contains more than two

SCENE. We diKingui in lyric mufic the fcene from the 
molo% in thab there is only one a&or in the monologue and at 
leatwo fpeakers in the fcen'e. Confequently in the onologue 
e chara&er of the mufic ould be one, at la in regard to the 
effon: but in the feehess the mufic ould have as many diffe- 
rent chara&ers as there, are fpeakes. In effe& as in fpeaking 
each one always continues the fame voice s the tfame accent, and 
generally the ame Kyle in all that ho fays  fo very a&0r, in th 
didrent paons he expreffe$ ould always preferve a chara&er 
peculiar to hims and which may diinguf'him from another 
a&or. The grief of an aged man, has not the fame tone as that 
Of a young one; the paon of a Billingfgate fi-woman, has dif- 
ferent accents from that of a warrior; A Barbarian c never faI' 
ß , zo.," rofe.mooCo. 
 ,utt then in fcenes render not only the chara&er.we 
would paint but that of the perfon whom we make to fpeak. 
This chara&er is partly denote by the kind of voice appropfiate8 
to each part; the urn in tinging of a counter-enor is different 
ffrom that of the bars tenor. We place more gravity in the aira 
of ba trebles and more vivacity in thol of fi:arper voice. 
But befide there differences, the ingenious compofer mu 
individual ones t0 chara&erize his pertbnages, fo that one all 
know in a moment by the pechliar accent of the reci. tative or 
aiq if it i Mandane or ra ' i, Off,re. or Mes Whom

mark there differences; but I fay however, that it is only in the 
bfervati0n of thems and others timilar, that we are able to produce 
tle illufion. 
SCHISMA. A fnlall interval, which is equal to the half of a 
Comma, and whoth numerical powers are c0nfequently mute, fince, 
t'0 expret's i in numbers, it would be necelTary to find a proportio- 
nal medixam between 8o and 8 . 
SCHOENION. A kind of nome for flutes in the ancient Greek 
ß uufc o 
scHOLIA. A kind t)f long among the ancient Greeks, whole 
qara&ers were extremely divertitled according to fubjes and per- 
gons. (rlde Son) 
SECOND. An interval of a conjoint degree wherefore the 
tonc movem'en'ts ace all made on the intervals of the fecond. 
There are 4 kinds of feconds. The fir called dlminifhed fecond 
i's made'on a majo't tone, whol inferior note ls conne&ed by a die- 
ils,. and the fuperior by a B flat; fuch, for infance is the interval 
0f the re ] fla't, t6 the ut dieils. The eonne&ion of this fecond is 
froin $'?5 to 384; but it is of no ufe, unlefs in the enharmonie ge- 
nus: the interval alfo is found null in virtue of the modification. In 
t'ega'rd ro he interval f one note to its diefis which Broffart calls 
xliminithed feeond, it is not a fecond, it is a changed unlfon. 
The fecond which is called minor fecond, is conituted by the 
major fetal-ton% as of  to ut or of mi to fa; its connexion is 
t"rom x 5 to 6, The third is the major fecond, which forms the 
interval of a tone; as this tone may be .major or minor, the refe- 
rence of this fecond, is from $ to 9 in the tiff[ car% from 9 to xo 
in the fecond-; But this difference is null in our mufic. 
Lafdy the fourth is the fuperfluous tcond, cornpored of a major 
tone and a minor femi-tone, as from fa to fol dieils '- Ira conne&i- 
on is from 64 to 75- 
There are in harmony two concords which bear the name of 
cond the tirf is timply called concord of tCond. It is a concord 
of varied feventh, whol diffonance is in the bars; from whence it 
ollows ver clCarl , that the baf lhould  rico ate to re are it. 
ß Y y y P P p 
(Vide to Prepare.) 
When the concord of feventh is dominant, i.e. when the third 
is major, the concord of the fecond is called concord Of triton, and 
the tyncope i not neceffary, becaufe the preparation is not fo. 
The other is called concord o fuperfluous fecond. It is a con- 
toed varied from that ofdiminilhed:feventh, the feventh of which 
itllf is conveyed to the bars.' This concord is equally good with 
or without a fvncope. (Vide Syncope.) 
SEMI. A vord borrowed from the Latin, which fignifle half, 
VFc ut it iri muff% initcad of the hemi of the Oreeks to compofe 
S E 
feveral' technical words very barbaroufly, the half Greek and the 
half Latin. This word, before the Greek name in any interval 
whatever always figMiles a diminutlon not the half of this inter- 
val, but only a minor fetal-tone; wherefore feml-diton is the mi- 
nor third; femi-diapent% the tall fifth; femi-diateffaron 3 the dimi- 
niflaed fourth. 
SEMI BREVE. Is, in our ancient.mufti, a power of notes or 
meafure of a time, which comprehends the fpace of two minime's, 
that is, the half of a breve. The femi-breve is however called 
round, becaufe it has that figure; but formerly it was in a lozenge. 
_Anciently the femi-breve was divided into major and minor, the 
major is equal to two thirds of the perfe& breve, and the minor to 
the other third of the fame breve; wherefore the major femi-breve 
contains two mia;ors 
The femi-breve, before the mlnime was invented, being the note 
of lefs power, was not rub-divided. This indivifibility, they fay, 
is expreffed in forne meafure, by its figure of a 1ozeng$ terminated 
above below, and at the. two fides, by points. Moreover Muris 
proves, by the authority of _Arifotle and Euclid, that the point is 
indivifible; from whence he concludes, that the lmi-breve enclofecl 
between four points is indivifible as themfelves. 
SEMI TONE. Is the finalleft of all the intervals admitted in 
mociern mufic; it is nearly equal to the half of a tone. 
There are feveral kiudiof fetal-tones, two are diffinguifhed in 
pra&ice, the major, and the minor; three others are known in har- 
monic calculations viz. The femi-tone maxime, the minime and 
the middle; tile femi-tone major is the difference of the majo- 
third to the fourth, as mi. fa. Its conne&ion is from S to (b and 
it forms the fmalle of all the diatonic intervals. 
The mnor femi-tone is the difference of the major third to the 
minor. It. is marked on the fame degree.by a dieils or a B flat; It 
forms only one chromatic interval and its reference is from o& 
to 2.. 
Though we place a difference between there two femi-tones by' 
the ;nethod of noting them there is none however on tile organ 
and harpfichord; and the fame ihmi-tone is tbmetimes major and 
tbmetimes minor, rometimes diatonic anti rometimes chromatic, ac- 
cording to the mode in which we are however in pra&ice. V½ call 
femi-t6nes minor, thole, which being marked by.a }3 flat or diefis 
do not change their degree; and fetal-tones major: thofe whicl 
form.an interval of the lecond. 
In regard to the three other femi-tones admitted only in the- 
ory .the .lhml-tone. maxime is the difference of tile tone major to 
the timi;tone minor, and its conne&ion is from $ to. a7o The 
middle femi-tone is tlxe difference major to the tone major, and its 
connexion i œom Z8 to $5' .aily, the œemi.ton minime, 
$ c 
is the dierence of the fetal-tone maxime to the middle fetal-tone, 
and its connexion is from x25 to x25, of all there intervals,.there 
is only the major femi-tone, ,hkh, ha quality of fecond, may be 
foreermines admitted into harmony, 
SEMI TONIC. A femi-tonic or chromatic fcale. (Vide Scale.) 
SENSIBILITY. A difpofition of the foul which infpires the 
compofer with the lively ideas which lie wants; the executant, with 
the lively idea ofthere fame exprefllons; and the uditor, with the 
lively imprefllon of the beauties and errors of mufi½ which he i 
made to hear. (Vid Taffe.) 
SENSIBLE. A fenble concord is that which is otherwfe called 
dominant concord, (Vide Concord.) 
It is prac"ticed only on the dominant of the tone; from whence it 
receives the name of dominant concord, and it always bears the 
fenfihle note for third of that dominant, fi'om whence it receives 
the name of fenfible concord. (Vide Concord.) 
In regard to he fenfible note. (Vide Note.) 
SEVENTI-I. A diffonant interval varied from the fecond, 
which is called by the Greeks, hepachordon, becaufe it is formed 
- of feven'founds or fix diatonic degrees. There are four forts of 
them. The firff is the minor feventh cornpored of four tone, 
three major and a minor and of two major feml-tones, as from 
mi to re: and chromatically of o fetal-tone% fix major and fou 
minor. Its conne&ion is froin $ to 9' 
The fecor:d is the major feuenth, compofed diatonically' oœ five 
one% three major and two minor, and of a major femi-ione; fo 
that no more than one major femi-tone is neceffary to cornpole an 
odave as from ut to ii, and ehromatically of   fetal-tone% fix 
major, and five minor. Its conne8ion is from 1 to $. 
The third is the diminiflaed feventh it is compofed of three tones, 
two minor and one major, and of three major femi-tones, as from 
ut diefis to fi B flat. Its conne&ion is froin 7.5 to x28. 
Tile fourth is the xCuperfluous feventh, it s compofed of .five 
tones, three minor and tvo major, a femi-tone major , and a remi- 
xone minor as from fi B flat, to !a dieils, fo that there is only  
comma wanting to it to form an o&ave. Its connection is from 
;8 to 6o, but this laft kind is not ufed in muff% unlels in rome 
½nharmonic tranfitions. 
There are three concords of the feventh. 
The firft is fundamental, and bears timpier the name of feventh, 
but when the third is major, and the feventh ninor, it is cfiled lin- 
fible or dominant concord. It is cornpored of thq third, the fit'th 
and the feventh. 
The feeond alfo is fundamental, and is called c=neon! of dlmi- 
nifhe41 fcventh; t is compoled of the minor third .the fallb fith, 
M m m  and 
and the dlmlnfhed feventh whole nme it takeg that is, oœ' thee 
minor confecutive tos, and 'is the only concord, which  tku 
formed of equat intervals: It is made on the fenfible note 
(Vide Enharmonic.) 
The third is called concord of fuperfluous feventh; it is a con- 
cord by fuppofition formed by the dominant accord; 'low which 
the bars makes the tonic be heard. 
There is alfo a concord of feventh and fixth, which is only a va 
flation of the concord of the ninth. it is only praifed in e or- 
gan points on account of its duration. (Vid Concord.) 
SERENADE. A ncert given in the night under t wlndow 
of rome one. 
tt is genesfly cornpored of inRrumental mufic; fomet;mes how- 
ever the voice is added to it. We call fetehades alib the pieces 
cornpored or executed on thefb occafions. The me of ferenade 
has been long obfolete; they continue no longer but amongff the 
lwer people, and that is a pity. The filenee of the night, whic 
banjoes all confufio% makes the mufic fuperio b a renders 
more delic/oas. 
This word, Italian in its origin, comes without doubt from fero- 
o, or fm the Latin rerum, in the evening. 'hen the concert 
is performed in the morning  or at break of day, it is called aubade. 
SESUI. A particle often ufed by our ancient muffclans in t 
compofition of words fering to exprefs the different torts 
Whey called SeCqui Alter's, the meafurcs whole pr;ncyal 
was equal to the half more than its ordinary power% that is, three 
of the notes of which otherwife it would have only equalled tw 
which ha place in all the triple mcafures whether in majo 
where the brevc itCelf without ints was nal to three fcmi- 
breves or in the minor where the fcmi-brv equalled three mi- 
'They called the triple,alfo fefqui alter marked by this n C 
, &uble fefqui fourth, the tripl marked C , and Co on with the 
8 4 
ß eR. Seffqui dito% or hi dito% in the Greek muff% is the intervM 
of a minor third. 
SEXTUPLE. A name given rather improperly to meafures o 
two times compod of fix equal notes, three for each time. Thef 
kinds ofmeafures have been alfo called by thllt improperly" 
timed meafures." 
We nmy reckon five kinds of there fextuple meafus, that is, as 
many' as there are different powers of the notes, from that which 
is compofd of fix rouads or femi-breves called in France triple of 
s 
{ix for one, and which is cxpreffed by this cyphcr  to that 
I 
tr,ple of fix for fixteen, cornpored only of fix double demi-crotchets 
6 
only, and which is marked alfo--. The greater part of there dif- 
6 
tin&ions are abolifhed, and in effc& they are rather ufelefs, trice 
all there different figures of notes, are le{'s different menlures than 
modifications of the mo'ement in the fame kind of menlure 
which is Rill better marked by a tingle word written at the head 
of the air, than with all the confution of cyphers and notes, which 
only ferve to increafe the difficulty of an art which is puzzling 
enough in itfelf. (Vide Double, Triple, Time, Meafure, &c.) 
SHARP. The alteration of a note or an interval by a dieils or 
]3 flat. This is properly the common and general name of the 
cidental dletis's and B's flat. The word is no longer in ufe, but 
there is no other fubituted in its place. The fear of ufing fuper- 
annunreal terms daily enervates our language; the fear of uting old 
terms decreales it daily: Its greateft enemies will ever be thole whi 
purify it. 
They called fharp a-lfo the chromatic touches of the keys, whleh 
we now call, white touches, and which were formerly made black, 
.becaufe our rude inceftors had not the ingenuity of making the 
keys black, to give a greater eclat to the Ladies fingers. We call 
at prefent cut fharps, thole of the touches which are broken to 
fupply the Ravalement. 
TO SKIP. We tkip a tone, when giving a Flute too muh 
wind, or in the pipe of a wind inerrnment, we force the air to be 
vided, and make inftead of the full tone of the flute, or pipe, onllr 
œome one of its harmonies. When the tkip is of an entire oOave, 
it is called to o&ave. It is clear that to vary the founds of the 
trumpet and french-horn, we mutt neceffarily tkip, and it is only 
in tkipping that we make o&aves on the flute. 
SI. One of the lven fyllables which they make ufe of in France 
to fol-fa their notes. Guy Aretin in compoting his gamut, invent- 
ed only fix of there fyllables, becaufe he only changed in hexa- 
chords the Greek tetrachords, tho' in the end, his gamut, as well 
as ours, was cornpored of feven notes. It happened from thence, 
that to name the feventh, it was neceffary every movement to 
change the names of the reR, and to name them in different man- 
ners: an embarraffmeut which continues no longer, fince the inven- 
tion of g, on the gamut, from which a muffclan, named de Nevers, 
made, in the beginning of this century, an exprefs work. 
Bropard, and tholi= who. have followed him, attr. ibute the inven- 
tion of li to another mullcain, named Le Maire, betwixt the middle 
and end of the lafl; centur}'; others give the honour of it to a certain 
Vandel 
,Vander PulIen: 0tlaers arcend as far as ean de tVfuris, about 
]rear.x 33 o, and the Cardinn! Bona, fays, that about the eleventh 
age, ;hih was that of Aretin Ericius Dupuis added a note to the 
tixth of Guy, to avoid the difficulties of the di.vifions, and facilitate 
he ffudy of mufic. 
But, without attending to the inventions of V..ricius ]Dupuls, 
avhich without doubt died with. him, or on which Bona, later by five 
centuries, maoYfa'se been deceived; it is even eafy to prove, tha: 
the invention much later than .lean de Muris, in. whole wri- 
tings we fee nothing fimil to it. 
In regard to Vander Pullen, r cannot fay any thing as I am not 
. acquainted with him Le M-aire now remains, in whof6 fayour the. 
voices of all feem to unite; !f the invention conrifts in having 
brought into praRice the ufe of this fyllable fi I do not fee many 
zeafons for difputing the honour with him. But if the true inventor- 
is he, who has firft found the necety of a feventh fyllable, and 
%vho las added one in confequence we need not fearch far 
o find, that Le Maire has no. claim. to this title; for e find 
treveralparts of P. J[erfenne's writings, the neceffi, ty, of the fe- 
venth fyllable to avoid the divifions; and he witneffes that 
œeveral had invented or pra&ifed this feventh fyllabte. nearly in. 
the fame time; and amongf others, Gilles Grand J. ean., writing 
aatter of Sens; but that rome named that fyllable cid. othei 
.eli, others ni others ti, others za, &c. Even. before P. Mer- 
.$'enne, we find, in a work of Banchieri, monk of Olivet, printed: 
n x6x4 and entituled Cartella di Mufici, the addition of the 
ame feventh fyllable; he ca[Is it Bi by B iharp, Ba by B flat,. 
and he affures ur that this addition has been very much ap 
proved at Rome. So that all the pretended' invention of Le 
llalre confit[s, at the moff in having written or pronounced. 
i, inffead of having written or pronounced Bi or Ba, Ni or 
and this is what has immortalized Le 1Malre. As to what remalns. 
the ufe of the fi is known only in France, and in fpite of what the 
monk Banchieri fays of it, it is not even preferved in Italy. 
SICILIAN. A kind of air for dancing, in the 6-- 4 or 
aeafures of a movement much flower, but yet more fpecified than. 
the ji. 
SIGNS. Are, in general, a.11 the different charaers made ufe of 
to mark the mufie. But this word is more particularly underoo& 
ef the diefi  B's flat, B's fharp, points, repeats paul'es, guidons 
and other fmall detached characters, which without being r. eal 
aote, are modificafion of notes and of the method of executing 
them. 
SILENCES. Signs anfwering to the different powers of the 
otes, which, put in the place of thole note mark that the lithole 
ff hcir time lould he paffed in fileace0 ' 
Tho  
'¾hd there are lo powers of dit'erent note, from the maximu 
to the quadruple demi-crotchet there are however onl 
ent chara&ers for the lences; or that which oght to 
pond to the maximum, has always failed, and to expefs its u- 
ration, we double the re fou. meafure% being of aa 
with the 1ongue. 
. There different filens are then, firR, the re of fo meafures, 
which is equal to a longue; Secondly e re of two roeslates, 
equal to a breve; Thirdly the paufe equal to a femi-breve 
Fourthry the demi-pf% equal to a minime; Fifthly'the minime 
-eR, equal to a crotchet; Sixthly the demi-minime re equal to 
demi-crotchet; Seventhly the quarter-mlnime reR equM to a don- 
ble demi-crotchet; Eighthly the demi-quarter mlnimereR 
o a triple demi-crotchet; and Ninthly the fixteenth of a ming 
reR uat to a quadruple demi-crotchet. 
We muR take notic% that the point has no place among filericeS 
as among notes; for tho' a crotchet and mlnime r ma be 
equal power% xt s not cuRomary to pmnt e latter to exprefs 
powers of a polned crotchet bu-t we ought after the minime re 
o write alfo a demi-minime reR. However as fome point the 
lences alfo, the executant tour be ready to all. 
SIMPLE. In doubles and variations the firR couptet or 
nal air, fuch as it is now marked, is called e mple. (Vidg

TO SING. Is, in its moR genel acceptafion to form Rro 
and varied founds by the voice. But it is moR generally the for- 
mation of diWerent inflexions in the voice, fonorous agrab 
the es% by intervals admitted in mufic and within the les o{ 
modulation. 
We ting more or lefs agueably, in proartion as the ice 
more or lefs greeable and fonorous; the ear more or lefs juR 
the organs more or lfs flexible; the taffe more or lefs formed 
and more or le pra&ifed in the a of fin. To which we 
ould add, in imitative and theatril mufic, the degree of fen- 
fibility which affe&s us more or lefs with the fentiments we 
to render. We have alfo mo or lefs difpotion towards finging 
according to the climate in which we are born and according t 
the more or left accent in our natural language. For the more 
accented the language is, and, confequently the more melodi 
ore tliofe who fpeak it have ihe facility 6f tinging it. 
' There has bn compofed an art ofngi, that ia obferv

endowment. But there rgmaln many difcoverie, to be mad% 
the Cafi OrtC gad fC nC Of aCg at art. 
SINGER. A muffdan who tings in a concert. 
SINGING MASTER. A muffclan who teaches the 'eading 
f vocal mufic, and fining on the notes. 
The functions of the tinging-mailer relate to two principal ob- 
jes. ' The tiril, which regards the culture of the voice, is to 
]raw from it all that can be given in regard to tinging, whether 
by the extent, by the juilnefss by the found, by the nimblenefs, 
or by the art of enforcing and fweetenlng the founds, and learn- 
ing io manage and modify them with all /he ingenuity poffible. 
The fecond obje& regards the ffudy of the figns, that is, the 
art of reading the notes on the paper, and the cullom of decy- 
phering it With fo much facility, that, at the opening of the book 
is'e may be able to ting every kind of mutie. (Vide Notes.) 
.A third part of the funions of the tinging-mailer regards the 
knowledge of the language, particularly of the accents, of the 
quantity and belt method of pronouncing thean; becaufe the er- 
rors of.pronunciation are much more fenfible in a long, than in 
converfation  and a well cornpored vocal, fhould be only a more 
energic and more agreeable method of marking the profody and 
accents.- (Vide Accent.) 
SIXTH. The fecond of two irnperfe confonances, called 
]exachord by the Greeks, becaufe its interval is. formed of fix 
founds, or fie diatonic degrees, The fixth is a natural confo- 
nance, but only by combination; for there is not in the order of 
confonances, any timple or dire& fixth. 
To conrider the fixth only by their intervais we find four 
kinds tvo confonant and the diffonant, 
The confonants are tiffS, the minor fixth cornpored of thre 
tones and two femi-tones major, as mi ut. Its relation is from 
five to eight. Secondly the major tixth, cornpored O f four tones 
and ß major femi-tone, as fol mi. Its connection is from three 
to five.- The diffonant fixths are; firil the d'maiaifhed fixth 
cornpored of two tones and three major femi-tones as ut dletis 
1/ fiat; and vhofe relation is from 5 to' 9 . Secondly, the 
œuperfit'.ous fixth cornpored of four tones, a major femitone and 
a minor femi-tone as fi B fiat and fo! diefis, The relation 
this tilth is from 7 to 
There two lail intervals are aever ufed in melody; an.d the d, 
nlnilhed fixth is omitted in harmony. 
There are revert concords vhich have the name of tilth. Th 
firR is timply called concord of fixth; it is the perfe& concord 
vhofe third is conveyed to the bars. Its' place is on the mediant 
of the tone, or on the fenfible note, or on the fixth. 
The fecond is called concord of fixth-foarth. This i alfo 
the perle& concord, whole fifth is conveyed to tlxe bari. It 
iaevcr made but on the dominant or on the tonic. 
Th 
s o 
-rhe th}rd is called c9ncord of finallet {ixth. It is ,a c.o, nq.ord 
f feventh whole fith is conveyed to the bars. The fmal!e 
fixth is conveygd ordinarily on the fecod note of fie toae or 
the. fiktli. 
The fourth is the concord of fith a..d fifth, or greater fixth, 
t is nifo i con'cord 0f feventh: bt whole third is cQnveyed to 
zhe ba'Es. If the fundamental concoi'd is domlnant: thn the con- 
c6fd of greater fixth lofts this nme, and is called concorg of fae 
fiftI. (Vide Falfe Fifth.) The greater fixth is commonly placed 
only on the fourth note of the tone. 
The fifth is the concord of fixth added. A fundament con 
cord: compofed as that of the greater fixth, of a third, a .fifth, 
a majo? fixthl and hich is placed in the fame moaner on th 
mn}c 8r fourth note. We can then diingui theft two con- 
cords only by the method of faring them; for.if the fifth ,de- 
icends and the fixth remain% t ts te concord of-gr.eater fixtll, 
aria th bfs forths a perfen cadence; but if the fifth remain.s, an4 
the fixth afcends it is the concord of fixtk added; and the fun- 
a,nental hals forms an irregular cadence. Moreovera a,. after 
having ruck thi! concord,  are maers of one of there t 
methods, this keeps the audience in fpence on the true founda- 
tion 0f the concord, until the end lxas determined it: and 'tis this 
liberty of choafinga that Moor. Raau calls dble-employ. 
(Vide that word.) 
The fixth concord is that oi major fixth and faire fifth whick 
is no more than a concord of fmaller fixth in mir node, 
which the falfe fifth is iubRituted in plat9 of the fourth; or 
exprefs mvfelf differently: it is a ccord of diminied taventh. 
in which he third is conveyed to the bars. It is pNced 
the fec0nd note of the tone. 
LaXly, The feventh concord of fixth, is that of the fuper-. 
fluous tixth. h is a kind of fmaller xth, which is nger 
but on the fixth nora of a minor tone deftending on thg domi- 
nant; as then the fixth of this fixth note is naturally maior; 
{s rometimes rendered fuperfluous by addi to i a difis. That 
4%perfluous fixtk then becomes an original Concord, which is 
overthrown or varied. (Vide concord.)

had no relation with ours, and was edablifhed on principl.es en-..

Guy d'rezzo, having fubfiituted his hexachord in the place 
of the ancient tetrachord, fubfiituted alfo, to fol-fa it, tix other 
œyl}ables to the fourth which the Greeks ufed differently. There 
fix fyllab}es are the following, ut, re, mi, fa, fol, la; drawn, as 
every one knows, fi-om the Hymn of St. John Baptitt. But: 
every one does notknoxv, that the air of this' hymn, as it is now 
tung in the Roman-church, is not exa&ly that frovo which Are-, 
tin took his fyllables  fince the founds which bear them in thia 
.h.ynn, are no.t there which be. at them in his gamut. We find,. 
an an ancient manufcript.. in the library of tlm Chapter of Sens,

and in which .each of the fix fyllables is exaOly applied to the 
correfpondent found of the gamut a as a.y be feen in Fig. Vt.

The ufo of ibngs feelns o be a natural confequence from tia: 
of words, and, in effe, is not lefs general; for wherever they' 
œpeak, they ting. It is only neceffary, for the conception of them, 
to extend the organs, give an agreeable turn to the ideas we are 
&lighted with, and fortify by the exlrefiion , of which the voice 
is capable, the fentiments ve xvould cbufe to render, or the image 
we would paint. The ancients had not the art of writing at the 
time they had of tinging. Their laws and their hifories, the 
praifes of tbdir gods and heroes, were fuag before they vere 
written. And from thence it happens, according to Arif'cotle 
that the fame Greek name was given to the laws and longs.

Thole'longs accompanied with the lyre and of vhich Terpan.

oblique, to denote according to Plutarch, the difficulty of the

thod of tinging, each one dtd not: fit in his rank, but only thole 
who unde'i-ood mufic, which were difperld here and thor% and 
placed obliquely with relations. to each other.

Greeks were ever animated. 
"Vin½ and health fays one of there longs, for my Clitagorg

betides that Clitagora was a Theftallan, the Athenians had for-

the rex, bec,ime alfo fongi of love. 
For partidular occafios, they had the marriage f6ng, Calleel 
.lr-Iymenea, Epthalamum; the f6n of Dates on merry occaiorm; 
a%{- l,imentations, the Jaleme; and:Linos for funerals, and other' 
nournful bccafi0ns. This Linos'was lung altb by the _YEgvp-

Imir princes, at Whole burial it had been lung. By a paffage oœ 
.nripides, cited by Atbenmus, we may fee th,2t the Linos all0

.aRly, there were alfo hymns or longs in honour of the gods 
.mud heroes. Such Were the Jule*s of Ceres and P, roferpne; the 
]Philtalin of pollo; the upinges of Diana, &c. 
This genus palTed from the Greeks to the Latins, and feveraI 
a>des o.f Horace are gallant or bacchie longs. But this nation 
ore warlike than tenfual, made s for a long time, but'a trifling 
afe of mufic and longs, and never ,'tpl>roached on this point to 
Ihe graces of the Greek. 
It feems that muSe ahvays ren-/alned rough and d;fcordant: 
mnongtt the lomans. What hey lung at marriages, was rather 
a/:Igmour than longs; and it cannot be prefumed, that the fatyv 
-ieal longs of the tbldiers, at tlm triumph of their generals, had 
a very agreeable melody. 
The moderns have their forgs Ifo of different kinds, accordin G

InGreat-Britaln it is Scotland; in Italy, it is Venice. 
Our longs are of feveral forts but in general on Lox, e or Vin%

are alfo called' tkdous; the romances, whofk charaOer is tQ move 
the foul infenbly by the tender and lively recital of rome amorous 
and tragic hi,cry; the paoral and runic longs, many of vhic 
are made 'for dancing, as the Muqettes the Gayors, &c.- 
The drinking longs are generally airs of bafs or ffmi-breves for 
tlte table. It is with great reatbn that few are made for the trebl% 
for them is not a viler and more dituing idea of debauchery than 
a drunken woman. 
In regard to fatyrle gongs, they are comprizeal under the name of 
audevilIes and dart their rays indifferently on vice and vlrtu% 
by rendering them equally ridiculous; which ought to profcribe thg 
vaudeville from the lips of perfons of morality. 
We have alto a kind of gong which is called parody. There 
are words adjued as we can on airs of the violi% or other infiru- 
merits, and which are rhymed either well or ill without paying 
attention to the menlure of the veres or to the chara&er of the 
air or to the fenfe of the words or even often to common deli- 
cacy. (Vide Parody.)

SOTTO VOCE. This Italian word fpecifies, in the places 
which it is written  that we mu only ting a demi-voix, or play 
onl 7 ademifiu. Mezzo forte, and mezza vote, fignify the three thine 
SOUND. When the agtatmn commumcated to the air by the 
collifion of a body ruck by anot[e% reaches as far as the audilive 
0rgan it produces a tnfation called noil. 'But there is a refound- 
ing noire katled found, Searches on the abfolute tbund belong 
to the phTfician. The mullclan examines only the relative found. 
He only examines by lnfible modificatlo% and it is according to 
this la ide% that we enqui.re into it in tltis article. 
There are three principal obje&s to tic confidered in the found; 
'the ran% the fore% and the modification. Under each of thelb re- 
lotions the found is conceived as modifiable. 1;'ifil from Hat to

fharp; fecondly from frong to weak; thirdly from flarp to fweat 
or from the dull to the lively, and fo reciprocally. 
I firft tuppofe, that whatever may be the nature of the foun// 
tliat its vehicle is the air itfelf; in the firft place, becaufe the air is 
the only intermediary body of the exiftence, vhich we are per- 
felly a'ffured of, be(ween the fonorous body, and the audilive or- 
gan: fince we muPc not multiply the beings without a ne6effity; 
as the air is fufficient to explain the formation of the found; and, 
moreover, beeaufe experience teaclaes us, that a fonorous body rend- 
ers no found in a place quite deprived of aii'. 
If ve would imagine another fluid, we may eafily apply to it all 
that I have laid on the air in this article. 
The refonance of the found, or to fpeak more clearly, its perma 
hence and prolongation, can afire only fi'om the duration of the 
agitation of the air. As long as tlxis agiiation continues, the tiaa- 
ken air incerrantly ftrik½s the audilive organ, and by this means. 
prolongs the fenthtion of the found. 
But there is not a more imple method of conceiving this durz- 
tion, than by fup?oing in the air vibrations which fucceed each 
other and thus renew the impre,on every inftant. Moreove , 
this ,-agitation of the air, of whatever kind it may be, cannot be 
produced but by a timilar agitation in the parts of the lbnorou 
body. Moreover, it is a certain facet, that the parts oftle fonorous 
body undergo fuels vibrations. If ve touch the body of a violin- 
cello at the time we draw the found, we feel it ake under our 
?and, and we fee very fentibl- the vibrations of the chord' continue, 
till the found is extinguifhed. ' 
It is the fame thing with a bell, which we make found by ftriking 
]t with the clapper; we teel it, we fee it even fhake, and we per- 
ceive the grains of thud leap up, which are throvn on the furface. 
If the chord Iootns, or the bell burrs, there is more flaking and 
more found. If tlxen, neither this bell nor this chord can commu- 
nicate to the air any movements, but what themfelves have, we 
cannot doubt but that tle found 1)roduced by the vibrations of the. 
fonorous body, exteuds itfclf by timilar Vibrations vhich this body  
communicates to the air. 
_All this being thppothd, let us ih'ft examine what conftltutes the 
a'elation of tbunds from fiat to 
I. Fheon, of Smyrna, flys that Lafus of Hermione, as well as 
the Pythagorean Hyppals of Mctapont, to calculate the relation 
ofconlbnances, made ul of two tlmilar veffels, which refounded 
unifon. That leaving one of thel cmpty, and filling a quarter 
Of the other, the percufiion of each prodt/ced the contnance of a 
œourth; that thn filliag the fccond a third then again the half 
tim 
s o 
the percufllow of the fecond had produced the confonance of the 
fifth, then of the oCtave. 
Pythagoras, according to Nichomachus and Cenforlnus, managecI 
in another manner, the calculation of the fame conneCtions. 
utended, they fay, different weights to the fame fonorous chords, 
artd determined the references of the different founds on thole 
which he found between the hanging weights; but the calculati- 
ons of Pythagoras are too juf'c to have been made in this manner; 
fince every one knows at preœent on the experience of Vincent 
lileus, that the. founds are together, not as hanging weights, but 
in the rub-double computation of thelb fame xvcights. 
Laftly, was invented the monochord, called by the ancients Ga- 
non Harmonicus, becaufe it gave tle rule of harmonic divifions. 
We muf'c explain its principles. 
Tvo cho,'ds of the lme cornpofition equal, and equally extend- 
ed, for,n a perfec"t unifon in every fenfe. If the lengths are une- 
qual, .the fhorteft will give a fharper found, and make more vibra- 
tions in a given time; from wlxence we may conclude that the dif- 
ference of founds froin fharp to flat, proceeds only by that of vi- 
brations formed in the fame fpace of time, by the chords or fono- 
rous bodies which make them heard: wherefore we exprefs the 
:onne&ions of founds h¾ the nmv, bers of vibrations which give 
them. 
We alfo know, by as certain experienc% that the vibrations 
the chord equal in every other refpe, a,'e always reciprocal in 
the lengths. So the double chord of another, will make, at the 
tme time only. the half of the number of vibrations of the latter, 
.and the relation of the founds, which they will caufe to be heard is 
called oCtave. If the chords are as. 3 to =, the vibrations will be 
as  to 3, and tlle conne&ion of the founds will be called fifth, &co 
( Vide Interval.) 
We fee by this means that with moveable bridges it is eafy to 
forxn On a fngle cho,-d, the divifions which produce founds in all 
offible conneCtions, whether together or with the entire chord. 
'œhis s the monochord which I have ju mentioned. (Vide 
1Vl.on ochord.), 
Ve may 'rerder fliarp or flat founds by other means; two 
chords of equal length do not always forin the unifon, for if the 
one ig,'eate' or le!-extended than the other, it will form left vi- 
brations in equal ti,xies, 'and confequentlt, will give a fharpe: 
found. (Vide chord.) 
It is ealy to explain on thef'e principles the confru&ion o chor 
intrument, iixch as the Harpilchord, and the playing of Violinn. 
or BaiTes, which by the different impreflion of the tingers or move- 
able bricl/es On 'tlx8 cltords products the divefilly of fbunda drawn

the wind inf'rruments. The holes, as in the flute and haut-boy 
œerve to fhorten theln, to render the found more fh.rp tn giving 
more wind, they' are made to oave, and the found becomes ftitl 
fharper. The co!mnn of air forms the fonorous body, and tho 
different tones of the trumpet and french-horn, have the fame prin- 
ciples as the harmonious founds of the violincello and violin &c. 
(Vide harmonic found ) 
If we make orc of thegrand chords of a violin or violincellc 
vefound with rome fm-ce, in pafi{ng the fiddle-ick rather nearer to 
the bridge than ordinary, we fl:ail hear di0dncVtly; however little 
our car m. ay be exercifed or ttentivc, betides the found of the en-

ble and 'ti in them khat himœelf and' 1VIonœ. ?artini have foughl;

( One difficulty which remains to be e?lained ir the tleory of 
the found, is t9 know hcw two or more founds may be heard at: 
the fame time. When we hear, for inftance,,the rw.o lbunds of the 
fifth, one of which forths two vibrations, whilft the other makes 
3three, we cannot welt conceive how the three mars of air may fur- 
nifh at the fame time there different numbers of vibrations diPtin& 
œrom each other; and fill lek, when it makes more than two fonds 
together, and that they are at[ dilTonant with each other. 
ß Mengoli and others manage the bufinel by comparifons' It 
the falDe thing fay they, as'whh two tones thrown in the water 
at the three time, and whole different circles lie crot ways without; 
confounding each other. Mont2 de Mairan, gives a more phi[otb- 
phicalexplanation. The air, according to him, is divided into 
particles of different fizes, each of which is capable of a cculiar 
P , . 
tone, and .hfceptible of no other; fo that in every found whmh 
formed, the particles of ah' analogous to it on[y, are lhaken, thole 
and their harmonies, whi[ft all the reft remain tranquil, till moved 
in their turn by founds corretondent to them. So that we lleat' 
at the fime thne two founds, asve fee two colours; bccaulb, being 
pro. duced by different parts they afro& tlm organ in diffgrenr 
This fyffem is ingenious, but the imagination is with difficulty 
xmlted to the infinity of the particle iv. the ir; dieœing in fize, and 
m(bility 
mobility, which ought to be expanded in each point of the fpace, 
lobe always ready on neceffity, to render an infinity of all the pof- 
fible founds i every place. When they are once arrived at th 
drum of he ear, we have Rill lefs conception, how, in fcriking 
veral together, they can produce a fhake capable of conveying tha 
fenration of each in particular to the brain. It appears, that thi 
difficulty has been rather removed than refolved. They alledge 
vain the example of light, whole rays meet in a point without con- 
founding the objeEts; for, betides that one difficulty is not refolved 
tiy another, the fimile is not exaPc, fince the obje ;s feen with- 
out exciting in the air a movement timilar to that which a fono- 
rous body mupc occafion to be heard. Mengoli feems defirous oœ 
preyelating this objeEtion, by fa ing that the maffes of the air 
charged, as it were, wth different founds, Pcrike the drum only 
cefiively, alternatively and each in its turn, without paying too 
great attention, how he t:hould employ thofe, which are obliged to 
ait ill the firPc have difcharged their office; or xithout explaining 
how the ear, fcruck with fo many fucceffive impreffions, can dif- 
tiiguifft thot which belong to each found. Irx regard to th= 
harmonies which accompany any found foever, they offer rather 
new care of the precedent difficulty, than a feparatembarraffinent;' 
for as loon as it is explained how many founds may be heard at 
time, we may eafily explairx the phcenomena of harmonies. Fox: 
inftarlce, let us fuppof6 that a found puts in motion the particleg 
of air futLeptible of that fame found, a.nd the particles fufceptible oœ 
:fharper founds ad infinitum, from there different particles there will 
then be founds,whole vibration beginning and finjib. lug exaEtly with 
the fonorous body, will be continually aided and renewed by thole 
of the other; there particles will be thole which give the unifon. 
Next comes the oc"tave, whole two %ibrations concording with on 
of the principal tbunds, are. affifted and enforced by it from. two to 
two: conlquently, the oPtave will be fenfible, but lefs than tha 
unifon. 'I'hen coius the twelfth, or oEtave of the fifth, which f9rma 
three prccii vibrations, whilPc the fundamental found makes one 
vhcrefore, receiv'ing a frefh fcroke only at each third vibration, tha 
twelfth will be let'tnilble than the oEtave, which reccivcs this 
trcfi fcroke at the fecond. By following tha fame gradation wa 
find the concourfe of vibrations more flow, the rokes lefs ren.ewcd 
and confequently the hartxlonies always lefs fenfible, 'until tile re- 
ferences ai-e cornpored to that point; that the idea of the concur- 
rence not ihfficiently freqtlent, be effaced, and tha vibrations ha. 
vlng tlfe time to be extinuilhed before they arc renewed the har- 
monic is no longer heard at all.

are very loon Prfled by thoFe of the chord and thls fharp found is 
abfolutely diffonant and null. 
Such is the reaœon why the firf harmonies are heard and all the 
rift are not re. But [ have written already too much on the firft- 
I' 
qua ty of tae found. Let us now paœs on to the repr. 
II. The force of the found depends on that of the vibrations of 
the loneroes body, the more there vibrations are Prrong the more 
vigorous the found is, and is heard at the greater diPrance. When 
the chord is fufficiently extended, and the voice or inprrument not 
too much forced, the vibrations a[vays remain itbchronous, and 
conœequently the tone continues the Gme, whether we ftrengthen 
or weaken the founct; but in Prriking too forcibly xvith the bov, in, 
flackening the chord too much, in tinging too high, we may make 
the vibrations lore the necelTary ilchronifin for the identity of the 
tone; and this is one of the rcafons, vhy, iu the French mufic, 
wherein the grand merit is to fcream} we are more fubje& to ting 
falfe than in the talian, where the voice is moderated with moro 
fweetncfs. 
The quickneœs of the found, whiclx would feem to depend on its 
force, does not re. This quickneœs is always equal, and conpranta 
nlefs accelerated or retarded by the wind; that is to fay, that the 
found, fkrong or weak, will be always uniformly extended; and 
two œeconds will always go twice the diprance it would do in one. 
ccorcling to Halley and Flamppread, the found in England goes 
o7o French feet in afecond and at Peru, 274 fathom% accordinõ 
to Monf. de la Condamine. P. Merfenn% and Gaffendi have 
lured us that a favourable or contrary wind neither accelerates oe 
retards the fouhd; but fince the experience that Derham and the 
_Academy of Sciences have nadc on this fubjc, this paffes as an 
error. 
Vithout flackenlng the motion the found is weakened in extend- 
ing itœelf and this weakening, if the propagation is fre% if it is 
not prevented by any obPracle, or flackened by the wind, ordinarily 
Ibllows the realbn of the tZluare of difkanccs. 
II[. In regard to the difference, xvhich is found alœo between the 
founds by the quality of the moditidatlon, it is evident, that it holds 
neither to the degree of elevation, nor even to that of the force. It 
will be in vain for a hautboy to place itlizlf in unifonwitha flut% 
it will be in vain to fweeten t:hc tbund to the fmne deffrce. Tha 
tbtnd of the flute will always hay% a je ne fids qoi ofnellow and 
fwect, that of the hautboy romething rude aud thartb which.will, 
prevent the ear from confounding them; without mentioning tlz 
diverfity of the modification of the voice. (Vide Voice.) 
There is not an inttrumcnt which has not its peculiar ten% vhic[x 
h.s no coaacitlor'witlx th.t of .n0thcr .nd ttxe organ alone ha 
twenty 
'twenty methods of playing all of a different modification. No 
i3ne, however, that I know of has examined the found in this 
tlcular; which as ;yell as the refc will perhaps be found to have 
t-ome difficulties; for the quality of the modification cannot depend, 
either from the number of vibrations, which forms the degree from 
flat to flarp, or from the greamefs or force of there fame vibrations,' 
ß a'hich forms the degree from ffrong to weak. We mu then find 
in the fonorous body a third different caufe from there two, to ex- 
plain this third quality of the bund 'and its differences; whiclx 
perhaps, is not too eafy. 
The three principal qualities which I have mentioned enter all, 
though in different proportions, into the obje& of mu% which 
found in general. 
In effe&, the cmnpofer does not only conrider if the found which 
he ufes ought to be high or low, flat, or arp, but if they ought 
to be rong or weak, difguing or fweet, dull or pleating: and he 
diRributes them to different inruments and different voices, 
recitatives or choruffe% at the extremities or in the medium of the 
inRruments or volces with the dolce and forte, according as thel 
are fuitable. 
But it is true, that it is only in the comparifon of founds from flat 
to arp, that the whole harmonic fcicnee cons; fo that, 
the number of founds is infinite, we may fay in the fame fenfe, 
that this fcience is infinite in its objes. We conceive no preciI 
founds to the extent of founds from flat to arp, and however 
froall the interval may be, which is between two founds, we flaall 
always conceive it d[vifible by a third found; but nature and art 
ve limited this infinity in the praice of mufic. We very room 
find in inRrmnents, the bounds of praaicable founds, as well in 
fiat as in arp; Lengthen or orten a fonorous chord to 
certain pmnt, t will have no more a found. 'e can neithe 
augment or dimini, at will, the capacity of a flute, or the pipe 
of an organ, neither its length. There are bounds paffed which 
meither can any longer refound. The breathing has alfo its inca- 
lure and its lavs. When too weak, it renders no found, whe 
too Rrong, it roduces onl a piercing cry, which it is impobl¾ 
to appreciate. Laaly, t s agreed, by a thouland expemences, 
that all fenfible founds are confined within a certain lhtitude,' 
paffed which, either too flat or too tharp, they are no longer per- 
ceived, or become inappreciable to the ear. Mon/. Euler has, 
in 'three refpes, fixed its limits; and according to his obfcrva- 
lions,/hewn' by Monf. IJiderot in his principles of the acouRic, 
all fenfible tbunds are cornprized between dm numbers 3o and 
552; that is to thy, that, according to this grcatgeometrician, the 
flatc found perceptible to the car forms 3 o vibratlona a fccond, 
anti 
-nd the fharpf ? vibrations at he œarne tme  an interval, 
hich narIy comprehends eiõht oavcso 
On the other land, we œe½ by the harmonic generation oœ œounds 
that amidff their infinity, there are very few which can be adtnitted 
into the harmonious fyftem. For all thoœe which do not form 
conœonances with the fundamental œounds, or which do not ariœe 
mediarely or immediately, from the differences of theVe confo- 
n'ances, 8ught to be proœcribed from the fyftem. This is the rea- 
fon, that however perfe ours may be œuppofed at prevent, it is 
however bounded to twelve founds only in the extent of an 
tare; from which tvelve, all the other oEtaves contain no more 
than replfiques. If we chufe to reckon all theœe repliques for fo 
many different founds, in multiplying them by the number of oc- 
taves, to whikh the extent of appreciable founds is confined, 
fhall find ninety-fix in all, as the greateft number of praEticabla 
founds in our mufic on the fame fundamental found. 
We could not reckon,.with the œame precifion, the number of 
'ounds pra&icable in ancient mufic. The Greeks forined, as it 
were, as many fyftems of tnufic as they had d'ifferent methods.of 
tuning their t&rchords. It appears, by reading their treatiVes 
mufic, that the number of theœe methods was great, and perhaps 
undetermlned. Moreover, each particular concord changed the 
founds of half he fyftem, that is; of twa moveable chords in each 
tetracho}d. So that we plainly' fee, that thcy had founds in a tin- 
gle method of concord; but we cannot julfly calculate how nmch 
this number was multiplied in all the changes of genus and mode 
which introduced new founds. 
In regard t:o their tetrachords, they diPringuifled the founds 
into two general claffe's viz. the fable. and fixfid' founds, whoœe 
concord'never changed; and the moveable founds, whoœe concord 
Changed with the nature of the genus. Tle fir were eight in 
all, viz. the two extremes of each tetrachords. and th.e. chord 
proflambanomenos; the œecond were alfo at leaft eight in number 
lmetimes' nine or ten, becaut two adjoining fdunds were rome~ 
irnes confounded in one, and rometimes feparated. 
In the p)'½ni genera, tliey divided the ffahle fountIs into two 
linds; one of which contained three founds, called apycni, be- 
caufe the 7 formed neither femi-tones, or finallet intervals in flat 
there three founds. apycnl, were the proflambanomenos, the neta 
fynnenenon, and' the nete. hyperboleon. .The other kind took 
the name of founds ba,'ypycni, becaul they formed the flat of 
the tinaller intervals: The tBunds barypcni were five in number 
iz. tlte hypate h aton, the h ate melbn. tl½ mcfis.the para- 
YP . YP 
mcfis and the h½c dmzcugmcnono 
The. 
'.e moveable tones were rubdivided in the/'ame manner into mefo- 
'hycni founds, Whi-ch were alfo five in nutnber, viz. 'The fecond 
in arcending of each tetrachord; and in five other founds c'lled 
ipbycni, wltich were the third in arcending of each tetrachord. 
(Vide Tetrachord.) . 
Ifi regai'd to the tvelve founds of tle modern fyftem, their con- 
e0rd 6.ever Chah=, and they continue i.,nmoveable. Broffard pre- 
tends, that they are all moveable, foundirig ,t on the,r being to be 
changed by dieils or B flat; but it is one thieig to change the chord, 
and another 'to change t'he concord of the chord. 
FIXED SOUND. To have vhat we call a fixed found, ve 
muft be affu,'ed, that this fouhd Would always be the fame, in all 
times and in all places. Moreover, we 'inuft not think it fufficient 
or this putpole, to have a pipe, for infkance, of a determined 
length; for firt}, the p'ipe always continuing the fame, the weight 
of the air will neverthelefs Change; the found will ;[lter ind become 
flatter or i'harper according as the air is lighter or heavier. For 
tile fame teafen, the found of the ,-me pipe will again change witN 
the column of the atmofphere, according as this fame pipe is railed 
or lmvered, in 'mountains or in vallies. 
In the fecond place, this pipe, whatever may be its competition, 
will be fubjecq: to the vai'itions that beat and cold cauts in the 
cli,nen6ons of every body. The pipe fimrtening, or lengthening 
itfel, will become proportionally fharper or flatter, and froin there 
two combined caufes, comes the difficulty of having a fixed found, 
and the alnioft impoffibility of being allured of the fame found, in 
wo places at the fame time, or twice in the fame place. 
If we could reckon exa&ly the vibrations which a found mak'e 
in a given kline, we might, by tile fame number of vibrations, be 
afrured of the identity of the found; but this calculation being 
1' 
'mpoffible we can on y certify the identity of the found by that 
of the inftruments which give it, viz. The pipe, in regard to its 
dimenfion; and tie air, as to its weight. Monf. Sauveur propo- 
td, for this purpofe, a inethod, which by experience did not thc- 
ceed. Mont; Diderot has fince pr9pofed rome more pra&icable, 
and wtiich conrifts in grnduating a pipe of a fufficient length, that 
its divifions may be jutc and iznfible, in competing it by two move- 
able parts, by_ which it may be Icngthened or flmrten&l, according 
to tile dimentions proportional to the alterations of tile air, expref- 
fed by the thermometer, in rcgard to their temperature, and by' 
the barometer as to their weight'.

tnent of it. 
FUNDAMENTAl-. SOUND. A fundamental found is that 
which fervcs as a foundation to the conco,'d. (Vide (]oncord,) or 
totlie tone, (\'id½ Tone.) 
P p p Fundament.t

Fundamental bar's, is that which foryes as a i6incati6fi t6 
mony. (Vide Fundamental Bars.) 
_ fundamental concord is that whole bat's is tundamental, and 
whofe founds are arranged according to the order of their genera 
tion; but as this order removes tlxe parts extremely, we connec 
them by combinations or variations, and provided that the bai 
continues the fame, the concord dogs not on that account fail to 
bear the name of fundamental. 
Such is, for inf[ance, this concord ut mi fo] confi'ned in zn in- 
terval of $th. whereas in the order oœ its genieration ut lot mi,

HARMONIC SOUNDS. A tingular kind of foands, whicl 
r drawn from certain inffruments, fuch as the violin and the 
olincello, by a particular motion of the fiddle-flick, which is drawn 
earer to the bridge, nd the finger lightly placed on certain divifi- 
ns of the chord. Their founds are very different for their mo- 
difications and for the tone, from what they would be, if the finger 
was confant[¾ fixed. In regard to the ton% for inRance, they will 
give the $th, when fley would have given the 3d, the 3 d, when 
they would give the 6th &c. As to the modifications, . they are 
much fweeter than thole which are drawn full from the fme divl- 
tion by carrying the chore} owards the flagVe and on account of 
this œweetnefs, they are called fluted founds. One muff, to have 
a clear judgment of them hv heard Mont'. Mondonville draw 
on 'his'violin or Monf. Bertdud or .his vioti'ncello,. the confe- 
rUences of thefe beautiful founds. By ftidi the finer flihtlv 
om fharp to flat, from the middle of a chor2' which ve touh a 
the fame time with the bogr in the aforelaid manner, we her dlf- 
in&ly  fucceflon of harmonic founds from flat to fharp; which 
ery much affonithes thfe uufkilled in the theory of them. 
The principle on which this theory is founded is, that . chord 
Eeln divided irto two. commenfurable parts to' 'ther and confe 
g .... g , 
quently wth the ermre chod ff the olacle which i placed at 
I]e .ont of divifion hinders only imperfe&ly the. commtinication 
of vibrations from one lart to another,. every time that the chord 
 founded in this ftate xt w11 not render fle found of the entir 
chord, nor that of its greate part but tha of the finallet parr, if 
it meaœures exa&l T th6 other  or, if it does not meafu.re i?, the

Let a chord 6 be divided into two parts 4 and  tha havmo.  
hie found will refound by the length of th fmall part e, which i

all the marvellous difappears, With a very timpie calculation 
we affign to each degree the harmonic found which anfwers to ito

which form no exa& divlfons, oœwhich form thofe that are too

cannot be admitted but in pracqice; for the harmonic tbund of

the bars, when ir enters into the concord and forms'a harmony,' 
allowing th difference of the notes ', which are thole of tafie, and 
œerve only to figure, but have no found. We alfo fay to found

SOURDINE. h fanall infirument of coppe: o,' filter, which is 
applied to tke b.ridge of a violin or. violincello, to render the tounds 
weaker, by intercepting and preventing the vibrations of the en- 
tire body of the inttrument. The fourdine, by wea!zcning the 
t'ounds changes their modification, and gives them' an' ekeceding 
moving and mournful characr. The French muffclans, vho 
think t13at fi fvfiet play produces the fame effe as th fourdine, and' 
who do: not admire the'trouble of placing and difplacing, make no 
ufe o; J;t:; bt3t they make u. fe of' it with great effe& in all the or-

SPACE. A. fair interval, or dif[ance, which is found in the 
ttave between a Iine, and that whlcli follows i immediately above 
or be}ow. There are four fpaces in the five lines, and two betides; 
tle one hbove, the other below the entire ftave: We find, wher/ 
neeeWary, tliefe t;o indefinite fpaces, by addiiional lines added 
abovd'or below, the which augment the extent of the Rave, or fur:. 
nifl hew/paces. Each of thel fpaces divides the interval' of two

SPICCATO. An Italian word, which, w. ritten on mufic, 
noteu fironE and-well'det.scl,ed founds. ' ' ' 
SPONDAULA. Was, arnOnEff the ancients, a player on tle 
flut% or 'rome other fi.ni'lar intk't ment, who, while the lhcrifiCe 
was offered played'in the ear"of the pricfl rome fuitable air, to 
prevent his. liftening to any thiug vl,ich might interrupt him, ' 
This word is for,ned from tl Greek wr0vl½, a' libation, and 
,uX0r, 'a Flute. 
SPONDIASM. Was, in the mof ancient Greek mutic, an 
rotation in the harmrode genu when a chord wa accidentally 
"' elc'vatdd 
eievatecl three dlefis:s above its ordinary concord fo that th 
œpondiafm was precifely the contrary to the Eclyfis. 
ß STABLE. The liable chords or founds were, betides the chord 
proflambanomenos, the two extremes of eaclx tetrachord, which 
extremes founding the diatepafon or fourth together, the concord 
never changed, as did that of the chords {n-the middle, which 
xwere extended or flackened, according to the .genera, and on that 
account were called moveable chords or founds. 
ß STAVE. The Praycot line ofmulic is cornpored of five parallel 
lines, on or between which the different pofitions of the notes 
mark their intervals or degrees. The Prave of church-mufi½ has 
only four lines: tt formerly had eight, according to Kircher, each. 
marked with a letter of the gamut; tb that there was only one 
c'onjoint degree from one line to another: When the degrees w. ere 
doubled, b.y placing notes in this manner in the intervals, the ftave 
of eight lines being reduced to four, was found of the fame 
tent as before. 
To this number of five lines in mufi½, and four in that oœ.the 
church, are added, additional or accidental lines, when n½cetrary, 
and the notes patk the extent of the ave above or below. This 
fixtent, in a Prave of mutic, is in the xvhole of eleven notes form- 
ing ten diatonic degrees, in ½hurch-mufic of nine notes forming 
eight degrees. (Vide Cleft, Notes, Lines.) 
ß 8TOP. Is tle termination of the phrafe, on which termina- 
tion the air repofes, more or lefs perfectfly. The Prop cannot-be 
aftab[it..ed but by a full cadence; if the cadence is avoided,

STYLE. The diPrinuCtive char/Eter ofcompolition or,execution. 
This characr varies greatly)'a½cOrdifig to the countries) th 
of 
s u 
of the people, the genius of authors, &e. aeeording to matters 
place, fuect, expreffon, &c. 
We fay, in France, the ftyle of Lull]r, ofRameau, of Mondon- 
ville, &c. In Germany, the ftyle of Haffe, of Gluck, of Graun. 
In Italy, the ftyle of Leo, of Pergolefis, of Jom'elli, of Butaneflu. 
The fty. le of church-ufic is not the fame as that for the theatre 
or a private room. The/'tyle of German compofitlons is lively s 
divided, but harmonious. That of the French compofition is flat s 
rouh. ill cadenced, monotonous. That of the Italian 
tion,'flourifhing, pleating, energetic. 
The dramatic or imitative ffyle ix proper for exciting or paint- 
ing the paffions.' The ffyle of the church is œerio. us, najeffic, 
grave. The ftyle of the Motet, where the artiff affects to fhe 
himfell as /'uch, is more claffic and ingenious, than energetic and 
affecting. The hyporchematic Pcyle is peculiar to jolt, pleafur% 
dan½ing filled with lively movements, gay and Well expreffed. 
The tmphonic or inftrumental ftyle. As every. inftrument has 
its touch, its fingering, its charaer peculiar to t, it alœo has its 
ftyle. The melifmatic or natural ftyle, which is firff prevented to 
perfuns who have not yet ftudied. The vle of fantaler, little 
united, filled with ideas, free from every ctnfraint. The chorale 
or dancing ftyle, which is divided into as many different branches 
as there are. charaers in dancing. 
The ancients had alfo their different ftyles. (Vide Mode and 
Meleepea.) 
SUB-DOMINANT. A name given, by Monœ. Rameau, ta 
the fourth note of the ton% which is, contEtiuently , in the fame 
interval of the tonic in deli:ending, as is the dominant in arcending. 
This denomination happens from the affinity which this author 
finds by variation, between the minor mode of the thb-dominants 
and the major mode of the tonic. (Vide Harmony.) 
SUB-M.'EDIANT. Is alœo, in Monœ. Kameau's ¾ocabular3, 
the name ot the fixth note of the tone. But thls fub-mediant 
as it ough to be in the three interval of the tonic below, as is 
the mediant above, fh0uld form a major third under this tonic 
and eorifequently minor third on the rub-dominant, and it is on 
this analogy that the fame Monf. Rameau effablifles the principal 
ofthe minor mode; bur it would folloxv from thence, that the 
major mode of a toni% and the minor mode of its fub-dominant 
muff have a great affinity; which is no thch thing: fince, on the 
contrary it is very tIdom that we pals fi'om one of thetE two 
modes to anothe% and that the' altooff entire fcale is altered by' 
fuch a modulation. 
I may be deceived in the acceptation Of there two precedent 
words, not t, aving Monf. Rameao's writiugs before me whilff I 
write this article.- H% pcrhapb underland timply by fub-domi- 
nant 
tant, the note, which is a degree below the dominant; and by 
'ub-mediant, the note which is a degree below the medianr. 
What keeps me in fufpenfe between thetk two fenfes is, that in 
each the thb-domlnant is the fame note fa for the tone of 
but it would not be the fame thing with the fub-mediant: It 
would be Ia in the firff tenfe, and re in the fecond. The reader 
may verify which of the two is Monf.'Rameau's: vhat may be 
tte'lSended on, is, that what I have given is preferable for the ufe 
of compofition. 
SUBJECT. A term ofcompofition. This is the principal part 
of the defign, the idea which ferves as a foundation to all the reft. 
(Vide Deftga.) 
dktl the other parts require only art and labuor: this depends onl3r 
on the genius, and, tis in this, that invention entirely conilLs. The 
principal rubjeers in mufic, produce Kondeau's Imitations, Fugues 
&c. (Vide thole $Vords.) 
dk barren and cold compofer, after havi.ng difcovered with diffi- 
culty rome fcattered fubjecøt, only turns it and changes it from 
tnodulatlon to modulation; but the artiff who has fire, and a clear 
imagination, without fuffering his thbje to be forgotten, gives it 
a new air every time it is reprefented. 
SUPEKFICIES. _A_ combination, either of the founds of a con- 
cord, beginning by one of thole founds, and takirg the reft ac- 
cording to their natural connexion, or, from ihe touches of the 
keys which form the fame concord. lVrom whence it follows, that 
a concord may have as many fuperficies as there are founds which 
cornpole it for each may be the firff in its turn. 
The perle& concord ut mi foI, has 3 fuperfi½ies. By the frtfl: 
11 the fingers are ranged by thirds, and the tonic is under the in- 
dex  by the fecond mi fol ut, there is a fourth between the two 
laft fingers and the tonic is under the laff; by the third fol ut mi, 
the fourth is between the index and fourth finger and the tonic is 
nder the latter. (Vide Variation.) 
As the diffonant accords have generally four 1otnds, they hav 
alfo four fuperficies, which may le/)und with the fame facility. 
SUPER, SUS. A name formerly given to trebles when they 
were very tharp. ß 
SUPEKNUNIER. AR. Yo Was the name of the loweft chord in 
the Greek fyffem; they called it altb in their language proftarnba- 
nomenos. (Vide that Word.) . 
SUPPOSITION. This word has two fnfes in mufic. Fir 
when tveral notes arcend or fall dia.onically in a part on the 
fame note of another part; theft: diatonic notes cannot then all 
form a harmon'y, or enter at the fame time into the Ihme con- 
cord, There are rome then counted lbr nothing, and thole are 
note foreign to harmony whiqh are called note b3' lhppofitin. 
The gefieral. rule is, when the notes are equal that all thb 
Which ftvike on the ftrong time bear the harmony, thole wh.icix 
pals on the weak time are notes of Ikppofition, which are placed 
for the air only and to fcrm conjoint degrees. Take notice th 
by rong and weak time I underand lefs the principal times. 
the meafure than the parts themfelves of eac h time.. So if there 
re two equal notes in a fame time it is the fir which bears 
the harmony: the fecon is of fuppofition; If the time 
CompoSed of four equal notes, the x and 3 d bear the harmo- 
ny, and the 2d and 4th are the notes .of fuppofltion, &C' 
Sometimes this order is perverted: we pat the fir note bF 
fuppofition, and we make the fecond borne, but then the pow r 
ers of this fecond note are generally augmented by a point at th 
expence of tl!e fir. 
11 this always fuppofes a diatonic m0vcmcnt by njoin 
degrees; for when the degrees are disjoint there is no fuppo; 
fition and all the notes ought.to enter in the concord. 
Secondly, we call concords by fuppofition, thole where the 
thorough bars adds or fuppofe a new found below the funda- 
mental bars: which occafios that fuch concords always exceed 
the extent of the o&ave. The diffonance of concords by 
pofition ould be always prepared by fyncopc's, and laved in 
defcending diatonically on the founds of a concord, under vhich 
the fame fuppofed bars may a& as fundamental bars, or,.. a 
leaas thorough bars. Vhich occafions the concords by .fup- 
pofition, well examined may all pals as pure fufpnfions. (Vid 
8ufpenfion.) 
There are three forts of concords by fuppofitont All are concoMa 
of the 7th: The fir, when the added found is a thiM below the 
fundamental, fuch is the concord.of the 9th, if the concord of th 
9th i, formed by,the mediant added below the fenfible concord 
the minor rood% the concord then takes the name of fuperfluou 
The fecond kind is when the fuppofed found is a 'sth.below thi 
fundamental as in the concord of 4th, or xth, if the concord 
fenfible and the tonic fuppofed the concord takes the name 
fuperfluous 7th. . 
The third kind i that xvhcre the foppored found is below a con- 
cord of diminifled 7th if it is i third below, that is that the 
fuppofed found be the dominant the concord is called concord 
fecond minor and third major. it is very little in ufe, if the fouled. 
added is'a fifth below, or that this found be the mediant the con 
rd iscalled concord of 4th, or fupcrfluous 5th and if it is a 7th 
below, that is, the tonic tthlf tle concord takes the n;tme ot 
nor 6th and fuperflt:ous 7th. In 
in regard to the variations of there different conco,-d% Where 
ih: fuppoffed found is tranffl>ortcd in the thperior parts, being ad- 
mitted only by licence, they ought only to be praaild xvith Choice 
ad circumffpeaion. We may iind at the word concord all titore 
which may be tolratd. 
SUSPENSION. There. is fiffpenfion in every concord on the 
bars, from which we Iain one or mfre founds of the preceden 
concord before we pat to thol whick belong to it; as if when 
the balk paWcs from the tonic to the dominant, [prolong rome mo- 
mentson that dominant, the concord of the tonic whidhprecedes 
it befor% relblvingit on its own, it is a fulenfion. 
There are fulenfions xvhich at'e cyphered and enter into har- 
mony. 
. When. they are dffOnant, they are ahvays concords by fuppofi- 
tion, other fufpenfions are only of tae } but whatever may be 
their natur%we 0ughk ahvays to tkbjeSc them to the three following 
L The fupenon ough alwa to be made on the roke of 
measure, or at lead on a itrng tme. 
i. It ought alway to be diatonically reqolvd, whether i 
tending or falling, that is that each part, which has fupended 
ought not immediatel to aVced or fall, but a degree to arrive 
the natural concord of the note of the N which has borne the 
fufpenfiOn. 
III. Every ft?penfi0n fyphered ought to be hved in defcend- 
ing, except the tingle tknfible note, which is fared in rifing. 
By the method of thcth.preeautions there is no fuqention But 
what may be praifed with tceel becaute in that care the ear 
prefenting on the bali the movement of the parts, fuppofes before- 
hand the concord which tbltows. But it belongs to the tae alone 
to ehootb and diribut% a Fropos the fu0enfi0ns in tinging and 
harmony. 
TO SUSTAIN. s to make the founds continue exa&lv their 
whole po'er% without fuffcring them to be cxtinguifixed be(ore the 
end, as tnuficlgns very often do, and particularly iynphoiis. 
. SYLLABLE. This name has been giv9n by lbme of the 
clents, and Nichomachu amontk the re2 to the confonace off 
the fourfib which they commonly called diatcqron, Whicl alfo 
proves by etymology, that thcy looked upon the tetrachord as we

SYMPHONIST, A compofer of Church mufic. This term 
is become technical finco it has been ulbd by Monf, L'Abbe 
Betfl. 
SYMPHONY, This w0rd formed from the Greek =du witlb 
and 'u tbund fignities, in ancient muff% that union of the foundq 
q q which 
S 
which form  concert. It is a fenfiment recelvec, and, i bell'eve 
'demonecrated, that the Greeks underMood not the harmony in the 
œenfe which we at prefent give to this Word. 
Their fymphony formed no concords, but refiffted from the con- 
currenee of federal voices or inttruments,. or of infruments joined 
with the voice, fitig.ing or playing the fame part. This vas dcm'½ 
two ways, where the whole conere-ted in' unitbn, and' the fympho- 
n¾ was then nore particularly called fiom'oph.ony, where the half 
o{' the concertants wa.q in the o&ave, or even m the double o,9cav 
of the other, and this was called antiphony. We find the proof 
of there dieciniong in' the problems of Ariftotle, Seion 2 9. 
-At pref_ent, the Word fymphony is applied to all inerrumenta[ 
mufic, as well for pieces whiet¾ are dePcined only for inPcruments 
as Sonata's and Concerto's,. as for rhot, where the inftruments are 
ound mixed with the 9oiee, as in our Operas, and in feveral forts 
of mufic. We difiuguifh vcal re. uric .into mmqCwithout fyma 
phony, which has at Ieat'c a treble of irecruments, violins, flutes, 
or hautboys. We fay of a piece, tlm it is in grand fvmphony 
when betides the bars arid treble ir has alfo two othe.r ini'trumenta'l 
parts, vlz. tenor, and 5th of the violin. 
The mufic of the King's Chapel, that o7 feveral Churches and[ 
of the Opera-Ltoufe, are almo always in grand iymphonv. 
SYNAPIffE. The con. iunecion of two tetrachardi, or mgre pre- 
cifely the refonance of 4th or diatcffaron, which is made between' 
the homologous chords of two conjoint tetrachords. Wherefor% 
there are three fynaphes on the Ieccm of the Greeks. The one 
between the tetrachord of the hypates, and that of the metis 
the other betwixt the tetrachord of the mefis and that. of the. 
conjoint and the third between the tetrachord'of the disjoint and- 
that of the hyperboles.. (¾ide Syem, Tetrachord.) - 
SYNALVLIA. A' concert of feveral nnficians, who, in Ancienlr. 
rimfie, played and anfwered each other alternatively on ftutes. 
ß vihout any union of the voice. 
Monf. IMalcolm wlo doubts whether the _Sncients had a 
tle cornpored o'nly for inftruments, does not fail to cite this fynau- 
lia fi'om xM'hen;eus, and he is in the right; for there fynaulia' 
were no more than a vocal mufie played by inftruments. 
$¾NCOPE. aX prolongation on the ftrong time of a found b-' 
[un on the 'weak time; wherefore, every lyncopated note is in'- 
counter thne, and every colic&ion of fyncopated notes is a move- 
ment in counter time. 
We mxtft take notice titat the fyvcope does not exif lefs 
lmrm0ny tho' th'e tbund whicli forms it inftead of hcing continued' 
flould be ftruck by two or more notes, provided titat the dito- 
tition of thet notcs which repeat the lhme.lbund be conformablo 
to thu dctinition. 'h'½ 
$ Y' 
'i'he f,vncope has its uœes in melody, for the exprettion and 
taffe of finding, but its principal utility is in the harmony for the 
prac'tice of"d. iffonances. The firff part of the fyncope irves for 
the preparatton. The difl'onance is fruck on the fecond, and in a 
œucceflion of diiTonances, the firft part of the following fyncop½ 
ikrves at the fame time to fare the ditronarme which precedes, and 
and to prepare that which follows. 
Syncope is from '2u with and x0'Tr'oJ t cut, becaufe the fyncope 
S:uts off from each time, oppofing, as it were with the other. 
Monf. Rameau derives this w. ord from the noire of the founds 
vhich knock againff each other in rome knd of diff'onance; but 
the fyncopes are anterior to our harmony and there are often 
fyncopes without a diiTonance. 
SYNNEMENON. Is the name which the G-reeks gave to their 
third tetrachord, when it was.conjoint with the feeend, and divi- 
ded from the fourth; when on the contrary it was conjoint to the 
fourth and divided from the feeend, this fame tetrachord took the 
name of diezeugmenon. (Vide that Word.) 
SYNNEMENON DIATONOS. Was, in 'Ancient muff% 
the third chord of the tetrachord fynnemenon in the diatonic ge- 
nus, and as that third chord was the fame as the feeend of the te- 
trachord of disjoints it bore alto in this tetrachord the name of 
trite diezeugmenon. '(Vide Trite, Syffem Terr.achord.) 
This fame chord, in the two other genera bore alfo the name 
of the genus in which it was ufed, but then it was not confoundeR 
witIx the trike diezeugmenon. (Vide Genus.) 
SYNTONIG. Is the epithet by wh. ich Ariffoxenes diffln 
guifhes that of the two fpaces of the ordinary diatonic genus  
Where tetrachord is divided into a fetal-tone and two equal tones; 
whereas in the flat diatoni% after the tEmi-ton% the firff interval 
.is three quarters of a ten% and the .other five. (Vide Genus 
Tetrachord.) 
Betides the fyntonic genus o.f Ariffoxenes, called alfo dintone di- 
atonic, Ptolemy effablithes another, by which he divides the tetra- 
.chord into three intervals. The firff of a thmi-tone major; the 
œecond of a tone major; and the thirst of a tone minor. This fyn- 
tonic dietonic of Ptoloiny remains, and it is alfo die only diatonic 
of Didymu, allowing this differece that Didymus having pla-

To begin by the t;roper and technical fenfe, I all fir fay 
that the name of fyacm xva given to every cornpored interval, or 
onceived as comp.ofcd of o$her finallet intervals, which confidered 
as the elements of the lflem, are caUed diaeme.

we ought to judge' of the condition and progrefs'of the ancient 
fyfre,n, by thotE of the inecruments deffined for their execution. 
For there inftru,ncnts accompanying the voice in unifon ancl 
playing all x hich they lung, muff form as many different founds 
as there entered into the fyftem: 
The chords of there firff inecruments were always touched, a vide, 
there were tten as many chords neceffary as the f.yftem c0ntainecl 
founds, and 'tis by this means that, xqnce the origin of mufic, we 
may deter.mine on the number of the chords of the inf'crument, 
the number of the ibunds in the fyffem. 
The whole fyffem of tlxe Greeks Was at firff cornpored only 
four Ibunds at the moff which formed the concoM of their lyre 
or cithara. There four founds according to fome were by con-- 
joint degrees according to others they vere not diatonic; but the 
two extremes founded the o&ave and the two middle divided 
into a fourth on each fid% and a tone in the midd  in the follow- 
ing manner  
Ut Trite Diexeugmenon 
Sol  Liehanos Melon 
Fa .  Parhypate Melon 
Ut Parhypate Hypaton 
This is what Boetius c11s he tetrachord of Mercury, tho' 
orus advances that Mercury's lyre had only three chords. This 
fyem did not long cpntinue confined to fo few founds. Clxorebe, 
on of Athis King 0f ydia, added a 5th chord; Hyagnis a 6th 
Terpander a 7th to equal the cumber of tlxe planets; and laKly 
ychaon of Samos, an 8th." ' 
Tltis is what Boetius fays  bt Pliny fays that Terpander 
ying added thre chords to the four ancient,: played th' on the 
cithara with 7 chords; that Simonides joined to it an 8th, and 
Timotheus a 9th Nicomgchus the Gerafinian attributes this 
8th choM to Pythagoras the 9th to TheophraKus of Pieria then 
a xoth to Hymus of Colophon and an xxth to Timotheus of 
Miler. Pherecrates i Plutarch mdkes a more rgpid pr0grefs to 
the fyem; he gives z2 chords to the fyem of Menalippedes, 
and as many to that of Tit0otheqs. nd as Pherecrates was 
contemporary xvith this great muffclan, fuppofing him effe&ually 
to have laid whgt plutch mak him f;j, hi witneflmg is 
great weight on a fa& which he had before his eyes. 
But how can we he affured of the truth amid to many contra- 
dic2ions, either in the d6rih e 0f uthrs' or"in the order of fa&a 
;rs they are reported ? For iRancc the tetrachoM of Mergury 
evidently gives the o&ave on the diapafon. How then could it b% 
that after the addition of three chords, the whole diagram ould 
be found diminifl;ed  degrc% and red6ced to an interval ' of 7th 
This

'This is however what the generality of authors would feem t 
anderftand and amongff the reft Nicomachus who fags that Py- 
thagoras finding the whole fyftem tompored only of t'o conjoint 
.tetrachords which between their extiemities formed a diffonant 
interval, rendered it confonant in dividing there two tetrachord 
by the interval of a tone s which produced the octave. 
However it be, it is a certain thing at leaif, that the fyffem of 
the Greeks was infenfibly extended as well above or below, and 
that it attained and even paffed the extent of the dis-diapaibn or 
double ocqave, an exte;nt which they called fyftema perred, urn, 
naximum, immeilatum, the grand fyftem, the perfeEt fyttem; 
that betwix its extremities which formed together a 
confonance were cortained all the fimple confonances, double, di? 
rec"f, and varied all the particular fyfems, ad according to thema 
the greate interval which can have place in melody. - 
ß This entire fyfkem was eompofed of four tetraho.rd, 3 conjoint 
and x disjoint, and a tone betides, which was added below all 
to cornpleat the double od'tave, from whence the cho. rd which for 
rned it, took the name of Proflambanornenas or added. Thi 
could not, it feer0s have produced more than x founds in the din- 
.tonic genus; Ir hs however tormed 6. This is that the disjune-. 
tion making itfelf pex'ceived rometimes between the fecond and 
third tetrachord, fometin3. es between the third and fourth; it hap- 
pened in the firfr car% that after the found In, the fharpef'c of the 
œecond tetrachorl followed in aftending th  natural which be- 
gan the third tetrachord; or, in tle fecond care, that this fame 
found Ia beginning itfelf the third tetrachord, was immediatelr 
followed by fib fiat; fqr the firft degree of each tetrachord in the 
diatonic genus, was always of a. femi-tone. This difference pro- 
duced then a 6th founti on account of he fi which was natural 
on one fide, and b flat on the other. 
The 6 founds were reprefen.ted by x 8 names; thai is to fay 
that thc ut and re being either flaarp tbunds or the middle of the 
third tetrachord acco. Ming to there two cafes of disjun&ion, 
name was given to each of there two found which determined its 
pofition. 
But as the fundamental found varied according to the mode 
there followed irom thence for the place which each mode occu- 
pied in the whole fyftem, a differen. ce fi'om flat to fharp, which 
multiplied fi:'eral founds; for if the different modes had tiveral 
cornmob founds, they h. ad allb .fore. e peculiar to each, or to a fe 
only. 'So, in the tingle diatonic genus the extent o_f all the founds 
admitted in the x$ modes numbered by Alipius is of three 
raves; anti, as the difference of the fundamental found 6f each 
.mode, to that of it ncighbou, wa only of  lni-toae it is evi-

iœed in the ancient mufic. If, deducing all the rephques of th 
fame founds, we confine ourfelves within the bounds of an oave 
we all find it divided chromatically into 2 different founds, 
in the modern mufic; which is manifeled by the infion of the 
tables placed by Meibomius at the head of the work of Alipius. 
Thefe reraarks are neceffary for eradicating the err o thofe 
who believe in the faith of rome modetns that ncien't mufic wa 
empo'fed in the wh'ole.of 6 f6unds. 
In regard to file enl5armonic genera and chromatic, the tetra- 
chords were therein found very well divided according t0 other 
proportions, but as khey alwayscontalned equally 4 founds, and 
confecufive intervals, in the fame manner as the diatonic genuf, 
each of there founds bore the fame na in their genus, whlc 
eorrefponded to them in the other  for which rfon I have glvm 
no paftlcular ables for eac h of thefe genera. 
The curious may confult thole which eibomus has placed a 
the head of the work of AriRoxenes. We all find 6i one for 
enharmonic genus, 3 for the chromatic, a  for the diatonic, ac 
cording to the dilotions of ea'ch of thefe genera, in the riox-' 
enian SyRem. 
ch was, in its perfeion'- the general vem ' of the Greeks, 
hich remained nearly in this condition to the xth century; the 
time, when Gui d' rezzo made a confiderable change. He.ad- 
ded below a new chord which he called Hyporofimbanomenos i 
0r hb-added and above,. a 5th tetrachofd Whlch' he Called e 
tetrachord of the fur- arp. 
Betides that, he invented, they fay, the b flat n'gceffary fo dif- 
tinguiing the fecond chord of a tetracord conjoint wth,ghe fi 
chord of the fame disjoint tetrachord; that ;'s to fyi that he fixed 
that double fignific1on of the letter B, which St. Gregory. before 
hhn, had ah'eady agned to the note fl. For fince it is certain 
that the Greeks had, for a long time thefe fame conjuions and 
disjunions of tetrachords and Confequently, figns to exprefs caen 
degree in thefe two different cates, it follows thence that it wa 
not a new /bund introduced in the fyRem of uy, ut only a new 
name, which he gave to this found, reducing by this means to onto 
ime degree, what amongR the Greeks forme two. 
We mu altb lhy of there hexachords fubRtuted in th place of 
their tetraclords, that it was lei a change to the fyem, than to 
the methocl, and that all which refulteH from it, was another 
thod of. lol;falng the ihme founds. (Vide Gamut To

of the keys in all the ancient organs. But at laff they found them 
felves incommoded bylimits, whatever fpace they might contain, 
they went beyond them; they extended above and below; they 
formed keys a ravalement; they forced the voice; and at laff 
gave fo much extent to this tyffeh, that it hag no greater bounds 
than thole of the violin.

ß The firf'c care of each formulze is placed when the interval come 
from 5ths. The fecond calk of each formulze is placed when 
the interval is derived from 4ths. 
To render this clearer by examples, let us begin by giving 
names to each of the x touches of the keys. 
There names, in the arrangement of the keys propoœed by MonL, 
de Boifgelo% are the following: 
Every ;nterval is formed .by the progreffion of 5ths br 
conveyed to the oave. For inffance, the interval fi ut is formed 
by this progr9tli0n of S fourths, fi mi la re tbl ut,.or by this pro. 
grcffionof fifths, ti fi'de be math (a ut. 
In the three manner the interval fa la is formed bY this progref- 
lion of 4'fifth % fa ul fol re la, or by this progreffion of 8 fourths 
fafamabedefifimala. 
Since that he conne&ion of every interval which is tlerlved 
! g S r 
from$hs isn,2. and that which comes from4th% is2 :n. it 
follow 
s Y 89-9 
follows from thence that we have for the conneCt[on of the inter- 
val fi ut, when it comes from 4ths, this proportion 
This is the method of proving the analogy. 
The number'of 4ths from whence this interval fi ut is &rived 
eing 5, the conne&ion of that interval is of --n fince the con- 
ns&ion of the 4th is : n. 
Bdt this connexion --n, would defign an interval of  feml- 
tones, fince each 4th has five femi-tones, and that interval has 
fourths. So, theo&ave having only xz femi-tnes, the interval 
fi ut would pals tvo o&aves. 
Then that the interval fi ut may be lees than the oave, we 
mu diminifi this reference 2 : n. of two oavgs; that i's,'oE 
te connexion of z: . Which is done by a connexion cornpole8 
o'f the dire reference 2n, and of the reference x2 inverfe 
of that --, in this manner : z+x. a+::2.  n::2:n. The 
interval fi ut, moreover coming from fourths, its conne&ion, as 
s r s r 5 
kave laid before, is a: n. Then : n :; a :n. and again s 
3 and r == $. 
S% reducing the letters of the fecond caffe of each formulm to 
e correfpondet gormul we have tot C 7 s 4r  x 
ox=o, and for D 
When the tme interval fi ut comes from $ths it gives this 
r s ß ? 
proportionn::: n:. So we have r= 7 ;=4 andconfe- 
qently, for the A of the fir ormul t   7 r  t = '4849 + 
o. nd for B. ax56 + r= xa 57 
In the frame manner the interval fa la coming from 5th 
tis proportion n:  :: n :., and conffcquently we have r 
 and s  . The fame interval coming from 4th% give.this 
proportion, 2: n :: 2: n. 
It would be too tedious to explain here the method of finding 
tl:e corms&ions, and the whole which concerns the intervals by 
the method of formula. It will be placing an attentive reader on 
Zhe rambl% to give him the computation of n and of its powers.

Remarks oa the tnterv.als. 
An interval  a given number of fetal-tones, has always two, 
iWerent conneaions5 lhe one'as coming fro m 5ths, and the other 
as coming from 4ths. The rum of thet tw6 powers of r in thefg 
o conneaions equal xz,an'd that of the two powers of s equals ? 
That nf the two connerions of 5ths or 4ths, in vhich r '! 
ler, is the diat0ni iteryal  the other is the chromatic. So. 
the inteal fi ut which hs there two conneaioas : n amd n: 2. 
is a diatonic interval, a! oming from 4ths, and ks connexion is 
a  n; but this fae interval fi Ut, is chromatic as comi fro 
lths, and its conneaioO is n: 2, becaufe in ;he firR care r + 5 is 
lefs than r = 7 of tlv tecond. 
On the contrary, the qtetvl fa la, which has its two conneai 
onsn. 2 :and2: n: is datonlcintherRcafe, wherelt come! 
from 3ths, and chromatic in the fecond where it comes from tks. 
The interval fi  diatoniC, is a !cond minor: Thd interval  
utj chromatic, or rather the interval fi fi dkfis (for then ut is taken 
 fi diefis) is  fuperfluous' nifon. 
The interval f la diatqnic, is a m4or thkd: The interval fa la 
chromatic, or rather the intetv mi dlefis I (for then fa is take 
 mi dieils) is adimithed fo'urth: So with the reR. 
It is evident, I. That to akll ditqnic interval there correfponds 
a chromatic of tke fe numar of fi-tones 'and vice verfi. 
There 
There two {nterval of the fame numler of feml-tones, the one 
dlitonic and the other chromatic, are called corretonder, t in- 
tervats. 
Secdly. When the powe{ of r is equal to one of there numbers 
o, , e, 3, 4, 5, 6, the interval is diatonic, whether that this in- 
terval comes from 5ths or 4ths; but if the K is equal to one 
of there numbers 7, 8, 9, o, x x, e, the interval is chromatic. 
Thirdly. When'r 6 the interval i in the fame time diato- 
nic and chromatic, whether it comes from sths or 4ths, fuch are 
the twointeals fa'fl called triton and fi fa, called falfe fifths. 
6 3 
The triton fa fi is in the reference n: e, and comes from 6 
4 6 
fifths: the falfe 5tk fi fa is in the connexion  : n, and comes 
from 6 fourths: where we fee, that in the two cafes we have r 
6 So the triton, as a diatonic interval, is a major 4th and as 
chromatic interval as fuperfluous 4tk. The falt} 5th fi fa, as 
diitoffic iraerrol, is a minor 5th; as a chromitic interval, a dimi- 
nixed 5th. ere are but thfe two i'ntervals and their replique 
which are lble 'to be at the time time diatonic and chromatic. 
The diatonic intervals of the 'fame name, and confequently ofth 
time gradation, are divided into major and minor. The chromatic 
!tevals are divided into diminied and fuperfluous. To each di- 
atonic interval minor, there correfponds a chromatic fapefluous 
interval; and to each daonic maior ipterval , there corrcfponds 
chromatic diminied interval. 
Every interval in arcending which comes from 5ths is mafor or 
giminied, according' as tka inteival is diatonic '0r chromatic; 
and reciprocally every 'major or diminied interval comes from 
fths. 
Every interval n afcendlng which comes 'from 4ths, is minor or 
fuperfiuous, according as tat interval is diatonic or chromatic, 
and. vice verfa, every ninor 0r thperfiuous iterval comes from 
fourths. 
It would be th contrary if the'interval Was taken in defcending. 
Of two intervals, colrefpondant that i% the one diatonic and the 
other chromati% and which confequently come, the one fi'om 5thss 
and the other from 4tlis, the greater is that which comes 'from 
4ths; and it furpaffes that which comes from 5ths in regard to the 
gradation by an unity ann, )n regard to the intonatio% by an in-

-towever little we praftice on this new method of pricking and 
i-darling the mufic: we fluall be tierprized at the neatnors, and tim- 
plicity which it g,ves the notes, and the fimplicity it conveys in 
the execution; without its being poflible to fee any other inconve- 
nience in it, than that it fills a little mo,-e fpace on the paper, 
and perhaps may dazzle the eye, in the quicker parts, by the mul- 
titude of its lines, and particularly in the fymphon¾. 
But as this f)em of notes is abfolutely chromatic, it feems to 
me to be inconvenient to fuller the denominations of the diatonic 
degrees to be fubftltuted in the place of it, and that according to 
Monœ. Boifgelou, ut re ought not to be a thcond, but a third; nei- 
ther ut mi a third but a fifth; nor ut ut an oc"tave, but a twelfth; 
fince each t%ml-tone really forming a degree on the note, flmuld 
tlœo take its denomination; then x+ x being a}ways equal to t in 
the formulae of that author, there formuIe would be found ex- 
tremely fimplih.'ed. Thi fyftem betides, appears to me.equally 
profound and advantageous. It would be a defi,-able thing for it 
to be explained, and publifhed by the author, or œome ingcniou

SYSTEM. Lafdy is the collocation of rules in harmony, drawn 
from rome common p,'inciples which gather them together, whikb_ 
form their union, from which they flow, and by which we form 
computation of them. 
Until our age, the harmony, born œucccffively, and, as'it were 
by chance, had only feattoted rules, ettablifhed by the ear, ;con- 
fir-reed by cullom, and whicl appeared abfolutcly arbitrary. Monf; 
Rameau is the firfir, who, bythe fyftem of the fundamental bars, haa 
given the principles of thefe rules. The fyftem on which thig 
di&ionary has been compoIkd, being fufficintly explained in the 
principal articles, flaall 'not be treated Of in this, which is already 
too long, and which there fuperfluous repetitions would extend to 
an excels. Betides, the plan of this work does not oblige me to 
expofe all the fyftems, but only to give a true explanation what 
fyftem i% and to ftrengthen, when neceWary, that explanation by 
examples. Thole %vho would wifia to t%c the diffut%d oblhurc 
of MonL Rameau by his writings, lain out with a'clearncl 
which it could not have been thought thtLcptible, may have re- 
courfe to the elements of mufic by Monl; D' xlembert.

on a double fundamental baFs: and as this author having travelled 
in Italy was not ignorant of onF. Tar6ni's cxpcrimcnts he 
compo&d from them joining them with thole of Rameau a mixed 
Zyffem which was'prind at Paris in 753 under this Title  EWay

the whole of it dpenFe with my giving any account of it to the 
public It is diCerent with that of the illuffrious MonF. Tartini 
which remains t0 bc tpoken of; the which as it is written in a 
reign language often profound and alws diFcd cannot be con- 
fuhed but by few pc0le the greateft pat otwhich are difcouraged

aJl that have been yet ublied, hat, who( principle is the 
timplc and from which the whole laws of harmony teem .to ar(e

Syffem of MonF. TartinL 
-hcr are three meoda of calculating the connerions of 
founds. 
I. dn cutting on the monochord, the entire chord into its parts 
by movabl b6dgs, the vibrations or founds will   the inve 
proportmn of the length of the chord and its parts. 
II.- In extending equal chords, by unequal Weights, ihg found 
w be as the fquare roots of the weights. 
III. In extgndg by equal eights, chords, equal in thickhers 
lad uncqu in iggthor'cqual in lth and unequal in thlckncfs, 
the founa' will 'be in te iverfe proportion of the fuirc roos 
ih dimcon,. wherein th difference is found. 
!a gner, the founds are always together in the invcffe pro- 
rtion of th cubic roots of fonoroug dies.' The founds of the 
hords ao moreover chaed three ways, viz. 'in altering either 
the. tcknc, that is {he diameter of the thicknefs or the length, 
or tcnfi0n. !f all this is equal the chords are in unifon. If only 
0ng of ihefg s changc th founds follow, in inverfe proportion, 
ti concaons 0f tll alterations. If two or all the three ar 
chaggcd, th founds arc, in invcrfe proartion, as the roots of the

And the founds which there chords would render are the faro% 
expreffed in notes in the example. 
By this means, all the founds which are in harmonic progrefllon 
aftel' the unity, are re.united to form one only fenfiNe to the ear 
and the whole harmonic fyftem is found in the unity. 
There is no found which makes any refonancc but fi'om its all-

whot vibration ftrike again each other, flops the vibrations of 
the equal parts, and are equally prevented by them; fo that of the 
two founds which would refult from it, the weakePc is dcfroyed

what Monf. Tartini calls unity or harmonic monad, from the 
concurrence, whence a lbund rcthlts. So, the whole of harmony 
being neceflhrily comprild betwixt the monad or cornporing unity 
and tile full tbuad or co,npofed unity, it follow tlmt harmony has, 
S ff 
S i 
on both fides, the unity for its term and conrifts in thae 
½iTentially. 
The following experiment, which-ferves as die principle o all 
artificial harmony, places this truth even in a cle=rerlight. 
Every time that two rong rimes, true and luria{ned, are heard 
at the fame moment, there refutts from. their fimck a third found 
more or lefs fenflhtc, in proFortion to the fimplicity in th connec- 
on of the two firR, and the nicety of the ear in the audience. 
To render this experiment as 'fenfibte as pobl% we td put 
two hautboys of a good goncord at rome paces of interval, and 
place ouriklves between them at an equal diance from each. If 
we ould be in want of hautboys, we mayatake o violins, whlcb 
tho' the/bund ould be weaker, may, by being toched wkh force 
and junefs b fucient to make a third found be diinguifiaed.

Form the fame operation on the major femi-ton% and the pro,

Tho' the production of the third found is not confined to theœe 
intervals, our notes not being able to exprefs any more compofed 
.it is uVeleVs for the prevent to go below thole. 
We fee ia the regular movement of the conœonances which.com-

and all p'oduce exa&ly the fame third found. 
Here then, by this new pha-oomenon, is a phyfical demonitratioa 
of the unity in the principle of harmony, 
Ih the Phyfico Mathematic Sciences, fuch as mufi% the demon- 
ß /rati'ons lhould be very gebmetrical, but phyficall deduced from 
the Mng demonfirated. 'Tis then alone that the union 
,calculation to phy% furnifhes, in eablifhed truths, both on 
ler[ence and geometrically demonftrated, the true principles of this 
art. Otherwife geometry alone will give certain theorems, but 
¾ithout uœe' in praetice: Phyfic will give particular faCts but with', 
out union together, and any general law. 
The phyfical principle of harmony is one, as we have/'een and 
it revolved l'n an harmonic proportion. Moreover, thefe two pro- 
prieties are fuitable to the circle; for we/hall Voon perceive, that 
the txvo extreme unities of the monad and founds are found therein 
and in regard to the harmonic proportion, it is found alt6, fince in 
vliatever point C, we unequally c'ut the dimmeter A B, for which.

The fqt. are of the ordinated C D, will be a proportionate hat-

roprieties of the circl% for the true foundations of the 5

I defignedly' pat's all the other propofitlons oœ Mont. Tartinl, or 
:lae nature of Arithmeti% of the harmony and geometry of the 
tirol% as well as on the bounds of the harmonic feries given by the 
fextuple computation; becaufe i'ts profs expreffed only in cvphers 
ettablifh no general demonffratio'n; and, &hat is mot%' bSr often 
comparing heterogeneous magnitudes, he finds proportions svhere 
ve cannot even fee connections. So, he would prove that the {'quare 
of a line is a proportional means of fuch a computation, he makes 
n'other proof, but that loch a number is a proportional means be- 
abftra,..c'c. 
tween two fueh other numbers. For the furfaces and  
numbers not being of the fame nature, cannot be compared. 
Monf. Tartini perceives this difficulty, and endeavors to prevent 
it; we may fee his reafonlngs in his book. , 
This theory being eftablifled, we mu now deduce its given proofs 
tnd the rules of the'harmonic art. 
The o&av% which engenders no fundamental found, not being 
effentlal to harmony, may be removed irom the conffitutive parts 
of tile concord. So, the concord, reduced to its greateft fimplicity 
.fl.. ould be confidered wi.thout it. It is then compoti:d of th½lE three

This perleft concord   produced 'by a/ingle chord and whoft 
$ 5 
terms are in harmonic proportion, is the general law of nature, 
which fcrvcs as a baœs to all the fciences of founds; a law whicl 
phyfic may endcavour to explairi but whofe explanation is utElefs 
to the rules of harmony. . 
T. he cal.culations of the chrds a, nd pendant weights ferve'to 
gi,e in numbers the conneCrtio, ns of the founds wlfich cannot be 
confidered as quantities but by favoc of.thet calcula. tions. , 
The third /bund, engendered by the concurrence of two othe% 
is as .the produ& of their quantities; and when in a common 
thegory ihi third found iS always found the fame, tho' engenderect 
by different intervals it i b that tile pr0du of the g0nerations 
are etlual together. 
Tlds 
g Y 
'lh]s is manlfeffly deduced from the precedent propofiri0ns. 
%Vhat, for inffance is the third found which refults from C 
andGB? It is the unifon of CB. %Vhyfo? Becaufe in 
two harmonic p¾oportions, whole fquares of the two ordinate 
parts C, C C, and G, G G, are proportional means, the fum of. 
the extremes are equal together, and confequently produce the 
fame common found C B or C, C C. 
In erie&, the rum of the two recq'angIes B C, by C, C C, and of 
A C, by C, CCisequal to the finn of the twore&anglesofB 
.by C, C C and of G A by C, C C: for e_ach of there t5vo ruins 
as equal to twice the fquare of the ray. From whence it follows, 
that the found C, C C or C B, fhould be common to the two 
chords; moreover, this found is precifely the note of the luff plate. 
Whatever ordinated parts you may take in the circle, to compare 
them 2 by 2, or even 3 by $, they will always engender rlm fame' 
third found reprefented in the plate; becaufh the r.etangles of th 
two parts of the diameter by the ray, will always gve equal rums. 
But the otave X Q.engender harmonies only in fnarp, and by' 
no means the fundamental found, becaufe we cannot elevate the 
ordinated part on the extremity of the diameter, and confequently 
the diameter and the ray in their harmonic proportions, have any. 
common product. . 
Inffead of harmonically dividing the diameter by the fra&ions 
! I ! I 
, which give the _natural f),ffe. m of the major con- 
23456 
cord, if we divide it arithmetically into 6 equal parts, we/hall have 
t]-/e fyffen of the major concord varied, anti th. is variation gi.vcu 
exaœtly the minor concord. See Fig. IV. Plate 
One of theœe parts .ill have the 9th that i% the double 
of the $th, tvo will give the I2th, or the o&ave of the $th, three 
will give the otav% four the $th, and five the minor $d. 
But, as loon as uniting two of there founds, we leek the third 
found, which they engender, thefe two tbunds inroad of the: 
found' C X 
will never produce as fundanental, any but the found E b; whlc}z 
prove% that neither the minor concord,. or its rood% are given b,r 
nature, If we make two or more intervals of the minor concora 
/ound toghc% the fundamental tbunds will be mukiplied and in, ' 
relation, 
relation to there founds, we fhall hear fcvcral major concords; af: 
the fame time, without any minor concords. 
So, by an experiment formed in prefence of eight celebrated 
profeffors of mufic, two hautboys and a violin founding the white 
notes together marked as follows: 
---- b 
fide founds marked in blank n the iame figure, are dnl 
vz. Thofe wMch are marked aftde as olows fr the nteaI 
which are abov% 
and thole marked next, for the intervals below. 
In judging of the horrible cacophony, which fhould refult from 
itxis concinity, we thould conclude that all mufic in the minor mode 
would be infupportable to the ear, if the intervals were true enough 
and the inruments fufficiently frong to render the engendered 
founds as fenfible as the generators. 
I beg leave to remark, en paint, that the invefe of two modes 
marked in a precedent plate, is aever bounded to the fundamental 
concord which conPdtutes them, but that it may be heard through- 
out the whole air, and harmony; which, note'd in a dire tnl 
within the major mode, when we reverie'the paper. an.d place clefts 
at the end of thole lines that are become the beõtuning, prelhnts 
another ]kite of air and harmony in minor mode, exa&ly the in- 
¾erfe of the fir, wherein the bal becomes the trebl% and rico 
verfa. , This is the cleft of the method of cornporing then double 
cano:? which I have fpoken of at the word canon. Monf. Settel 
before mentloned who has very clearly explained in his book this 
harmonic cur;ofity, introduces :i fymphony of this kind compol;:d 
by Monf. de Merambeff who thould havre had it engraved. 
That 
"hat Would have been ce'rtairlly be:tP than hayling ;t e:eeuted. 
A compofition of this natfire mutt be better to prefent to the eye 
iha'n the. ear. 
We hae feen ha from l:he harmofiic divifion of the djameter 
i, efults the major rood% 'arl rro'tit the arithiriet'icltl divifion, the 
minor mode. It is betides a known thing of all the theoricians 
that the conne&iorl of the minor concord ai'e found in the arith- 
metical cli'vitlon of the $th, To find th6 fit;f{ foundation of the mi* 
hot mode in the harmonic fyllem it is fufficient to l'hew in thin 
i-yem tlie arithmetical di.viiion of the 5th. 
The vbole harmoriii: i'yllem is founded on a double eomputation 
he c0nneion of the entire ch6'rd to its oave., or of the diameter 
to the ray; and 0ri tle fefqui aiier eofnputation which gives the 
11rPc harmonic or fundaniental found to which all the repc a?c 
t:onne&ed. 
Moreover, if in the double comprltati0% we compare ftlccefllvely 
he fedond note G. and the third F ofthe feries P.tothe funds-.. 
mental found O.a.- and to its flat o&ave which iS the entire ½hord 
W'e/hall find that the firft is aft harm0riic means and the fecond an 
arithmetical means between thofe two terms. 
In the fam'e matmet; if in the fefqui alter computation we com- 
pare fuccefilvelfkhe 4th note % and the 5th eb of the Came feries 
to the 'entire cliord and its $th Gi qre fhall find that the 4th e 
an harmonic means, and th* 5th eb an arithmetical means be- 
tWi'Xt the two terms of this 5th'- The 'minor mode fhen being 
lounded on ihe arithmetical divifion of the 5fh, and the note eb 
taken in the feries of the complements in the harmonic fyllem 
giving this divifion, the minor mode is founded on that note in 
the harmonic fyllem. 
After having found all the eonfonanees in the harmonle diviliorl 
of the diameter, the major mode in the dire& order of there con- 
fonan'½e% the minor in their retrograde order, ahd in their ½om' 
ptement% there remains to examine the third exampl% wlfich 
prell'es in notes the conne&ions of the ti:lua?es in the ordinated 
parts and which gives the fyPcem of diffonances. 
If we join, by confonances, the fufceffive intervals of the above 
exampl% we fhall find that to fquare the ordinated parts is to 
double the interval whleh they reprefent. So, adding. a third 
tbund, which repreti:nts the tituare , this added found wall always 
double the interval of the confonance as we fee in the following . 
plate. 
Thus the firPc note K of the above example doubles the oave 
the firPc interval of the other example; the fecond note L doubles 
tile fifth the fecond interval; the third note M dorahies the.fourth 
T t t the 
the thirci interval, &c. and tls this doubling of intervals 
expreffed as follows 
C c- 
- o '- ,o --? ' ,T 
Generation of Diffonances. 
which is 
Leaving axqde the oave oF the fifi interval, which engendering 
no fundamental {ound ought not to pals as harmonic, the adde 
note L forms, with the two which are below it, a thorough geo- 
metrical proportion in fefquialter computation, and the following, 
always doubling the iritervals, foein alfo always geometrical pro- 
portions. 
But the proporti6vls ahd progreohs harmonic and arithmetical 
ß vhich conRitute the confonant major and minor fyffem, are oppo- 
fed, by their nature, to the geometrical progreiilon; fince this 
refults eitntlally from the fame conne&ions, and the others from 
connerions always different. Then, if the tWO proportions har- 
monic and arithmetical are confonanf the eometrlcal proportion 
will be neceffarily cliftonant; and, confequently the xayfem 'which 
efults from the former example, ig'ill be the fyem of diffonances. 
ß 'But this iyffem drawri from th6 f'quares of the ordinated parts is 
xnlted tO the two precedent, dra(vn from the fquares ofhords. The 
cliftonant fyRem is then united in yhe fame manner to the aniverfal 
larmonic lyRere. 
It follows from thence, flr, That every concord w11 be difl'o- 
nant when it contains two timilar intervals, others than the o&ave; 
whether there two intervals be found conjoint with, or feparatel 
from the concot&' Secondly, that of thefe two intervals, that 
which belongs to the harmoleic or arithmetical fyfem flall be con- 
fonant and the other cliftonant. So in the two examples S T of 
cliftonant concords in the followin late, the intervals G C and ½ g 
P . . 
are ½onfonan G and the interval's  F and e g dxf/'onant 
In conneing however each term of the diffonant ferles to the 
fundam'ental found or engendered C of the harmonic ferieswe thai[ 
lind that the diffonance which rcfult from this connexion will be 
the 
e following, and the 0nly direEt ones which ½m be eftablithecl

If we hive clearly underflood the generations and analogies 
the three orders or fyftems, all founded oa the firft, given by 
ture, and all reprefented by the parts of the circle or their powers, 
we flaalI find firif, That the particular harmonic fyftem, which 
gives the mtjor mode, is produced by the fextuple divifion in hat? 
montc p'ogreffion of the diameter, or the entire thoM, confidered. 
as the unity. Secondly that the arithmetical fyffem-from whence 
the minor mode refults, is produced by the arithmetical ries of 
the complements; taking the fmaller term for the uniy, and raifing 
it from term to term as far as the fextple computation, which at 
laff gives the diameter or the entire chord. Thirdly that the geo- 
metKcal fyffem, or the cliftonant i glfo drawn from the harmonic 
yffem by doubling the powers o each interval; from whence it- 
oIlows, that the harmonic fyffem of the major mode, the onIy one 
immediately giyen by atre, rvs as a princple and foundatioq 
to the re. 
By what haa been yet fald, we fee that the harmonic fyem is not 
cornpored of parts which reunite to torm the whole -but n the 
contrary it is from the divifion of the whole, or the integral unity 
that the parts are drawn; that the concord forms t6 itfelf do 
founds but that it gives em; and that laxly, wherefoever tke 
armonlc fyem has a place, the harmony does not defiv; f 
the melody;but the melody from the harmony.

ther timilar inruments produce, as may be feen in the plate by

1LIowever, the Common fcale, tho' not n concord wth the ferles 
of the alkluots , has not a 'Jefs phyfical and naturaforlgin to be 
explained. ' 
The portion of the firfc feries O, which determines the harmonic 
fyfcem, is the fefquialter or $th C G; that is, the o&ave harmd 
nically divided. 
Betides, the two terms, which correfpond to' there in the ferles P 
of the complements, are the notes G F. There two chords are the 
middle; the one harmonic the other artificial, betwixt the entire 
chord and its half, or between the diameter and the ray; and 
there two middle G and F being conne&ed both to the fame fun- 
damental, determine the tone and even the mode, fince the harmo- 
nic proportion predominates over it; and they appear before the 
generation of the minor mode, having no other law than that 
which is determined by the harmonic feri½s, from whence they are 
derived; the ought each to bear the chara&er, vlz. The'perfe& 
major concord, cornpored of major 3d and $th. 
If then we conneff and range fuccefllvely, according to the near- 
eR order, the notes which confcitute there three concords, we fhall 
have very exaly, as well in mufical notes, as in numerical con- 
neations, the oave or ordinary diatonic fcale rigoroufly efta- 
blifhed. 
In notes, the thing is evident by a tingle operation. 
In numerical conneRions, this is aimoft as eafily proved, for 
fuppofin, 36o for the length of the entire chord, there three notes 
'C, G, 1 , will be as x8o, 4o 7o; their concords will be as 
follows: 
and the entire fcale œeduced from it, will be in the conneions 
marked as follows:

Where we fee that'all the intervals'are iuft, except the perfe 
concord, D F A, in which the $th D A i; weak by'a omma, aa 
well os' the minor third D F, on account of the minor tone D E; 
but in every fyfiem this error or an ecluivalcat one is inevitable.

From the natural fuccefllon of there three cadences, ruth'as we 
fee it in a former plate. There refults exa&ly the fundamental bari 
. oœ_thefcale 4 and.fromtheir different intermixtures-isderived the m 
thoct' of treating. any tone, and modulating on. ik a feries of airs 
for each note.of'.the cadence. is fuppofd5 to.bear the perœe doncord 
ß as has been laid before. 
Irt regard to what is. called "The Rale. of the O&ave", it is evi 
tent, that tho' we fiould not even admit the'harmony which it 
œpecifies as pure and regular, as it is found onl ttxrough dint of 
art"and:du&ions, it can never be propofed in clualiy of princi- 
ple and a generaI law. 
The compofers of the 1$th age, the generality of .whom wer 
xcelIent harmonifts uthd the whole fcale as a fundamental baf 
of as many pe'rfe& concords as it had notes, except'the 7th on 
account o(the falfe $th; and this harmony well Condu&ed, would 
have formed a very reat effe&, if the perle& concord on the men 
diant had not. beer/ndered too h.rfh ly there two faire relations 
with.the concord Whicl, precedes it and that vhich foI10wSa 
$Y 
ß To render this ferles of perfe& concords as pure and fweet as 
.pcsflible, we muff reduce it to this other fundamental bays, whiclt 
œumifhes with the precedent, a new fource of varieties. 
As we find in this -formula, two perle& concords in minor third, 
viz. D A, it will be neceffaxy to leek Xbe analogy which the major 
and minor tones fhould have together in a regular modulation. 
Let us corr. fider the note. eb of the example P, united to the 
.two correfpondent notes of the examples 0 and'Q. taken as 
fundamental: it is found by this means aS the' Bale, or foundak 
lion of a concord in major third; but taken-as an arithmetical 
xneans between the entire chord and its fifth, as in t.he example 
of the other plate: it is .then found mediant or fecond bale of th 
xninor mode: So this three note, confldered under two different 
eferences, and both deduEted from the fyftcm, gives two hartno- 
,-airs; from whence it follows, that the fcale of the major mode is 
a minor third above the analogous fcale of the min6r mode. 
Wherefore the.minor mode analogous to the fcale of ut, is that 
-of In, and .the minor mode ?alogous to t:hat of fa, is that.of re. 
Moreover, la and re, gve exa&ly, in the fundamental bays of 
the diatonic tkale, the tw.o'minor concords analogous to the two 
tones of ut and fa, determined by the two harmonic cadences of 
nt to fa and.of fol to ut. The fundamental ba, wherein we make 
there two concords enter, is then as regular, and more varied than 
..the preceden.t., which only contains the hagmony of the minor 
.mode. 
In regard to the two la diffonances n an'r of the example' q, as 
they come from .the diatoni. c. genus, we will not yet fpeak of 
t lie nl, 
The origin:of the meaœure, the periods., phraf'e% and all the mu- 
-fical rhyme, is found alf'o in the generation of the cadences, in 
their natural (eries, and ,thei different co. mbinatioris. Firft, the 
ß means beiog immogenous to its extreme, the two members of a 
cadence ougkt in their firf'c fimplicity to be of the fame nature and 
$qual powers. Confequently the eight notes Which form the four 
kadences, the fundamental bays of. the fc-ale, are equal together 
ahd forming alfo four equal meafu,'es, one for each cadence, tlm 
whole gives' coinpleat f'enfe, and an hnrmonic period. 
Moreover, as the whole harmonto fyftem is.founded on the dou- 
ble and fefqui alter computation, which on account of the 
is confounded with the triple powers, in the fame manner every' 
good and fenfible meafure is refolved on that of two times, or that 
of three, all which is below, often attempted, and always unfuc- 
cefsful, not being able to produce any good eftcO. 
From the different foundations of ha,-mony given by the three 
forts of cadence, and from the different methods of i,atermixing 
thcm arifcs the variety of the tnfes of phrat% and the  hole me-
