Music bows with a string and a gourd functioning as a resonance body are widely spread throughout the whole of Africa. In Bahia, it became the berimbau. It is played by balancing the instrument with the left hand at a right angle to the body. A stone or coin is held between the thumb and forefinger, with which one can modify the timbre and pitch of the string. A thin stick held in the right hand together with a caixixi, produces the typical buzzing sound by striking rhythms on the metal string. The berimbau is the most characteristic instrument of Capoeira.
