Most percussion instruments have a certain sound, even the sound of drums. But generally speaking, the classification of percussion instruments is to see whether an instrument has a certain pitch. However, some percussion players determine the pitch of their drums before recording or performing special works.

Drum is a percussion instrument. A tight membrane is covered on one or both sides of the drum body, which is solid and generally barrel shaped. The drum can be sounded with hands or a drum-pestle. Drum is an important instrument in African traditional music and modern music, and some bands are entirely composed of percussion instruments mainly based on drum. In addition to being used as an instrument, drums were also used to spread information in many ancient civilizations.
