SlapsThe Vibraslap is a percussion instrument and is mainly used in Latin-American music. It consists of a U-shaped piece of spring steel as a handle, at one end there is a wooden box with loose metal pins and at the other end a wooden ball. To play the Vibraslaps hold the instrument by the handle and hit the ball on the free hand. As a result, the loose pins vibrate in the wood resonator and produce a sustained, rasping noise. Due to the Vibraslap's steel spring the vibration is sustained longer. The Vibraslap is the modern variant of the Quijada. This consists of the lower jaw of a donkey, in which instead of metal pins the loose teeth rattle. The Vibraslap is often heard in Cuban music. It also serves in film music as an effect instrument that creates tension or anxiety.
