Clapper (musical instrument)

Clappers can take a number of forms and be made of a wide variety of material.

Several specific forms of clapper have their own names, such as the Chinese guban, Japanese hyoshigi, or the Korean bak.

In music, a whip or slapstick is a clapper (percussion instrument) consisting of two wooden boards joined by a hinge at one end.

The percussionist holds the instrument by the handles and hits the two pieces of wood together, creating a loud whip noise.

The whip is sometimes indicated in scores by the native words for "whip" (French fouet, German Peitsche, or Italian frusta) or a term indicating the clapper construction (French claquette or German Holzklapper).
