Berimbau

Musical bow from Africa.

Some information from Wikipedia:

The berimbau is a single-string percussion instrument, a musical bow, from Brazil. The berimbau's origins are not entirely clear, but there is not much doubt on its African origin, as no Indigenous Brazilian or European people use musical bows, and very similar instruments are played in the southern parts of Africa. The berimbau was eventually incorporated into the practice of the Afro-Brazilian martial art capoeira, where it commands how the capoeiristas move in the roda.

The berimbau consists of a wooden bow (verga), about 1.2 to 1.5 m, with a steel string (arame) tightly strung and secured from one end of the verga to the other. A gourd (cabaça), dried, opened and hollowed-out, attached to the lower portion of the Verga by a loop of tough string, acts as a resonator.

To play the berimbau, one holds it in one hand, wrapping the two middle fingers around the verga, and placing the little finger under the cabaça's string loop (the "anel"), and balancing the weight there. A small stone or coin (pedra or dobrão) is held between the index and thumb of the same hand that holds the berimbau. The cabaça is rested against the abdomen. In the other hand, one holds a stick (baqueta or "vaqueta" – usually wooden, very rarely made of metal) and a shaker (caxixi). One strikes the arame with the vaqueta to produce the sound. The caxixi accompanies the vaqueta. The dobrão is moved back and forth from the arame to change the pitch produced by the berimbau. The sound can also be altered by moving the cabaça back and forth from the abdomen, producing a wah-like sound.
