Percussion instrument Originated in the ancient eastern civilization and Egypt, there are Spanish folk percussion instruments. According to research, the metal part of Egyptian castanets was replaced by fruit shells, forming Spanish castanets.

Castanets are mainly used to accompany songs and dances, and later used in European art music, using two pieces of shell-shaped ebony or mahogany to make sounds. At first, two pieces of wood were tied to the thumb and middle finger respectively, and then played in the palm of your hand, or on a wooden handle, or played with a board in both hands. Castanets make a hard clicking sound, which is lively, crisp and distinctive.
