The largest kind of Mexican _teponaztli_ appears to have been generally of a cylindrical shape. Clavigero gives a drawing of such an instrument. Drums, also constructed of skin or parchment in combination with wood were not unknown to the Indians. Of this description was, for instance, the _huehuetl_ of the Aztecs in Mexico, which consisted, according to Clavigero, of a wooden cylinder somewhat above 3 feet in height, curiously carved and painted and covered at the top with carefully prepared deer-skin. And, what appears the most remarkable, the parchment (we are told) could be tightened or slackened by means of cords in nearly the same way as with our own drum. The _huehuetl_ was not beaten with drumsticks but merely struck with the fingers, and much dexterity was required to strike it in the proper manner. Oviedo states that the Indians in Cuba had drums which were stretched with human skin. And Bernal Diaz relates that when he was with Cortés in Mexico they ascended together the _Teocalli_ (“House of God”), a large temple in which human sacrifices were offered by the aborigines; and there the Spanish visitors saw a large drum which was made, Diaz tells us, with skins of great serpents. This “hellish instrument,” as he calls it, produced, when struck, a doleful sound which was so loud that it could be heard at a distance of two leagues. The name of the Peruvian drum was _huanca_; they had also an instrument of percussion, called _chhilchiles_, which appears to have been a sort of tambourine. The rattle was likewise popular with the Indians before the discovery of America. The Mexicans called it _ajacaxtli_. In construction it was similar to the rattle at the present day commonly used by the Indians. It was oval or round in shape, and appears to have been usually made of a gourd into which holes were pierced, and to which a wooden handle was affixed. A number of little pebbles were enclosed in the hollowed gourd. They were also made of pottery. The little balls in the _ajacaxtli_ of pottery, enclosed as they are, may at a first glance appear a puzzle. Probably, when the rattle was being formed they were attached to the inside as slightly as possible; and after the clay had been baked they were detached by means of an implement passed through the holes.
