Membranophone

A membranophone is any musical instrument which produces sound primarily by way of a vibrating stretched membrane. It is one of the four main divisions of instruments in the original Hornbostel-Sachs scheme of musical instrument classification.

According to Sachs,

The sound is produced by a membrane ["skin" or "head"] stretched over an opening. Most, but not all, membranophones are generally called drums. They are classified according to

material, shape, skin(s), skin fastening, playing positions, and manner of playing.
