This type is more observable among savage tribes than among civilized nations. Folk-song is therefore not so permanent among the former as it is among the latter. So far as we can gather, though it is difficult to get at the truth of this matter, among primitive people the savage does not appear to retain his song-traditions, but invents new lyrics as occasion calls. For example, one is continually reading in books of travel of negroes, or natives of wild countries, chanting extemporary songs descriptive of things which have been the happenings of the day, and telling of the white man who has come among them, of the feast he has provided, of the dangers they have encountered during the journey, and so forth. The tunes of these songs appear to be chiefly monotonous chants, and the accompanying music of the rudest character, produced on tom-toms, horns, reed-flutes, or similar kinds of instruments. A very typical description of this class of folk-song, the like of which may be found in most books of travel, occurs in Day’s _Music and Musical Instruments of Southern India and the Deccan_. The author says:— “The ordinary folk-songs of the country are called “Lavanis,” and will be familiar to every one who has heard the coolies sing as they do their work, the women nursing their children, the bullock-drivers and dooley-bearers, or Sepoys on the march. The airs are usually very monotonous, the words, if not impromptu, are a sort of history, or ballad in praise of some warrior, or ‘burra-sahib.’ Some have a kind of chorus, each in turn singing an improvised verse.” This type appears to be the origin of a nation’s folk-song. It is a sign of a country’s civilization when it begins to keep records, either by tradition or more fixed methods, and it is a theory (which may be probably accepted as correct) that chronicles were first chanted in ballad form and thus more easily passed downward in remembrance. This may be accepted as the origin of the folk-ballad. Its music has originated by the same natural instinct that produces language. Much has been said of the communal origin of folk-song and folk-music, but it is somewhat difficult fully to realise what is meant by such a term in relation to these matters. Those who hold this theory appear to assert that a folk-song with its music has had a primal formation at some early and indefinite time, and that this germ, thrown upon the world, has been fashioned and changed by numberless brains according to the popular demand, and has only met with general acceptance when it has fulfilled the requirements that the populace have demanded. This change is called its “evolution,” and it is sometimes claimed that this evolution still goes on where folk-songs are yet sung; this means that the folk-song is virtually in a state of fluidity.
