TUNES 53 tains some association of detail which is not found in the words; it may, for instance, be found in a particular part of the original country, or arise at some specified date. Were all collections of ballad tunes as ample as those of Germany, it is probable that we should be able to notice more migrations of melodies than at present appear. A simple instance of migration (because of its relatively recent date) is Marlbrough s'en va en guerre. The tune may come from a seventeenth-century hunting song, but it suddenly sprang into popularity in 1781 through being sung by the Dauphin's nurse and taken up by Marie Antoinette. It spread abroad so rapidly that Goethe heard it almost everywhere on the road to Naples. The melody has the curves indicated by the formulas 4!^ in France (Doncieux), B3A in Germany (Erk und Bohme), and 9621A in Catalonia (Pelay Briz). The French and German tunes are identical in all but the first interval, and a detailed transcription would show that this affects only one note. The Catalan differs in the first interval, and takes the third in two stages; it also differs in time and key, and in the arrangement of the lines. In an older song traditional variations would be more numerous, as in The poisoned Marchioness. This also is a French song, referring to the hapless Gabrielle d'Estrees, who died in 1599, under the usual Renais- sance suspicion of poisoning. The tune occurs in France in the variants 6625C, B225BBA, 522, EiABB22, and in Germany in the variants BB22, BB223C, BBC73C. In the course of four centuries considerable changes have occurred in the melody, but one can still discern the group BB22, or its mathematical equivalents, in most of the versions. The Shipman (El Marinero) is a ballad of French origin, and its passage from Catalonia to Castile is evidenced by the formulas 52266 and 522BBE. In the same way we may trace La Porcheronne from France to Catalonia, and Lord Randal from England to Italy. In really old cases of migration the evidence is often obscure. The migrating tune may have died out in its original land, or it may have been changed out of all recognition. So the famous Herr Ribbolt, which is our Douglas Tragedy, has one Danish tune (^52148221) which might be connected with a Swedish tune (IC2I2C243B); another two (535A35C and SE5E522iA) which seem related to the Norse (5E54BG) and also to a simpler Danish tune (52202) which resembles one in Norway (522iAB2iA). These last two tunes are the nearest one can bring
