. "A Bat\u00E1 drum is a double-headed drum shaped like an hourglass with one cone larger than the other. The percussion instrument is used primarily for the use of religious or semi-religious purposes for the native culture from the land of Yoruba, located in Nigeria, as well as by worshippers of Santer\u00EDa in Cuba, Puerto Rico, and in the United States. The Bat\u00E1 drum's popular functions are entertainment and to convey messages."@en . .
