Berimbau– the berimbau is a single-string, bow-shaped percussion instrument fromBrazil. The berimbau consists of a wooden bow about 4 to 5 feet long with a steel string tightly strung and secured from one end to the other. A gourd that has been dried, opened and hollowed-out is attached to the lower portion of the bow and acts as a resonator. The berimbau is used in musical performances and in the practice of the Afro-Brazilian martial art Capoeira, where it commands how the capoeiristas move in the roda. It is also used in a group rhythmic process called TaKeTiNa.
