We have seen how naturally the percussion instruments were developed; how they sprang into being, as it were, in response to an innate necessity for rhythmic expression, an inevitable accompaniment of the dance and the dance-song. Almost at the same time wind instruments of a simple and rude kind were fashioned. Whistles were made from the bones of animals with the marrow removed. Pipes were made from hollow reeds, while conch shells and the horns of deer-like animals furnished the first trumpets. These primitive whistles, pipes, and deer-horn trumpets[5] when blown were capable of giving forth but one tone. However, it is highly probable that, as their makers grew more familiar with the effect of the varying pressure of the lips, certain partials of the fundamental tone were produced, such as the octave, the fifth, and even the third. Eventually a series of holes were pierced in them, thus making it possible by means of stopping and unstopping these holes with the fingers to produce a rude scale of tones. But the first whistles were evidently of the one tone variety. An interesting relic of this description has recently been exhumed by N. Lartet in the department of Dordogne, France. It consists of a small bone, probably of the reindeer, about two inches in length. Through this bone near one end a small hole has been bored, probably by a sharp piece of hard stone, like flint. By applying the lips to this hole and blowing strongly a shrill whistling sound is produced. This was no doubt used in hunting, or as a call. In a cave at Lombrive in the department of Ariège several dog-teeth with similar holes for whistling have likewise been discovered.
