Another instrument also, the _bull-roarer_, dates back to the beginnings of music, though its development, of course, differed from that of the zither. The bull-roarer, indeed, is an instrument of tone and noise that is to be found only among relatively primitive peoples. True, it does not reach its highest development among those peoples who, from a sociological point of view, occupy the lowest plane of culture; it becomes an instrument of magic, as we shall see, only within the totemic culture of Australia. Nevertheless, there has been discovered, again among the Bushmen, a form of bull-roarer of an especially primitive character. Doubtless that which led primitive man to the invention of the zither was the tone which he heard in his everyday experience in war or in the hunt when he applied an arrow to his bow. No doubt, also, it was the whirring noise of the arrow, or that, perhaps, of the flying bird which the arrow imitates, that led him to reproduce this noise in a similar manner. Indeed, in South Africa, the bull-roarer, though, of course, used only as a plaything, occurs in a form that at once reminds one of a flying bird or arrow. The feather of a bird is fastened at right angles to a stick of wood. When the stick is vigorously swung about in a circle, a whistling noise is produced, accompanied, particularly when swung with great rapidity, by a high tone. This tone, however, is not capable of further perfection, so that no other musical instrument developed from the bull-roarer. The contrary, rather, is true. In other forms of the bull-roarer in which the feathers were displaced by a flat wooden board--whose only resemblance to a bird was a slight similarity in form--the noise was more intense but the tone less clear. For this reason the bull-roarer soon lost its place in the ranks of musical instruments and became purely an instrument of magic, in which function also it was used only temporarily. In many parts of the world, moreover, there is a similar primitive implement, the _rattle_, whose status is the same as that of the bull-roarer.
