The berimbau is a single-stringed percussion instrument, a stringed music bow with a gourd, which originated in Africa, became the berimbau in Bahia and is now commonly played all over Brazil and worldwide. You balance the berimbau with your left hand vertically in front of your body. A stone or coin is placed between the thumb and index finger of the same hand. This can be used to change the timbre and pitch of the string. In the right hand, together with a caxixí, you hold a thin stick which you use to tap the string and produce the typical buzzing sound. The berimbau is the characteristic accompanying instrument of the martial dance capoeira.
