If the preserved antiquities of the American Indians, dating from a period anterior to our discovery of the western hemisphere, possess an extraordinary interest because they afford trustworthy evidence of the degree of progress which the aborigines had attained in the cultivation of the arts and in their social condition before they came in contact with Europeans, it must be admitted that the ancient musical instruments of the American Indians are also worthy of examination. Several of them are constructed in a manner which, in some degree, reveals the characteristics of the musical system prevalent among the people who used the instruments. And although most of these interesting relics, which have been obtained from tombs and other hiding-places, may not be of great antiquity, it has been satisfactorily ascertained that they are genuine contrivances of the Indians before they were influenced by European civilisation. Some account of these relics is therefore likely to prove of interest also to the ethnologist, especially as several facts may perhaps be found of assistance in elucidating the still unsolved problem as to the probable original connection of the American with Asiatic races. Among the instruments of the Aztecs in Mexico and of the Peruvians none have been found so frequently, and have been preserved in their former condition so unaltered, as pipes and flutes. They are generally made of pottery or of bone, substances which are unsuitable for the construction of most other instruments, but which are remarkably well qualified to withstand the decaying influence of time. There is, therefore, no reason to conclude from the frequent occurrence of such instruments that they were more common than other kinds of which specimens have rarely been discovered. [Illustration: FIG. 16.――POTTERY WHISTLES. Ancient Mexican. British Museum.] The Mexicans possessed a small whistle formed of baked clay, a considerable number of which have been found. Some specimens (Fig. 16) are singularly grotesque in shape, representing caricatures of the human face and figure, birds, beasts, and flowers. Some were provided at the top with a finger-hole which, when closed, altered the pitch of the sound, so that two different tones were producible on the instrument. Others had a little ball of baked clay lying loose inside the air-chamber. When the instrument was blown the current of air set the ball in a vibrating motion, thereby causing a shrill and whirring sound. A similar contrivance is sometimes made use of by Englishmen for conveying signals. The Mexican whistle most likely served principally the same purpose, but it may possibly have been used also in musical entertainments. In the Russian horn band each musician is restricted to a single tone; and similar combinations of performers――only, of course, much more rude――have been witnessed by travellers among some tribes in Africa and America.
