A sample of an unaccompanied berimbau: ( ogg format, 17 seconds, 174KB).
The Berimbau consists of a wooden bow ("verga" - traditionally made from "biriba" wood, which grows in Brazil), about 5 feet long, with a metal string ("arame" - traditionally pulled from the inside of an automobile tire) tightly strung and secured from one end of the verga to the other. An opened and hollowed-out gourd ("cabaça") is attached to the lower portion of the Verga, secured by a loop of tough string. This acts as a resonator.
To play the berimbau, one holds the berimbau in one hand, wrapping the two middle fingers around the verga, and placing the little finger under the cabaça's string loop, and balancing the weight there. A small stone or coin ("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" - usually wooden, very rarely made of metal, as a metal baqueta produces a bad tone on the Berimbau) and a rattle (" caxixi"). One strikes the arame with the baqueta to produce the sound. The caxixi accompanies the baqueta. The dobrão is moved back and forth from the arame to change the tone of the Berimbau. The sound can also be altered by moving the cabaça back and forth from the abdomen.
Parts and Accesories of the Berimbau:
There are three types of Berimbau.
The berimbau, as normally played, has a relatively small repertoire of sounds. However, subtle differences in the way each sound is played give the berimbau a very organic and musical sound. The basic sounds are:
Other sounds are also used (the dobrão can be moved after the arame is struck, the cabaça can be struck directly) and the movement of the cabaça controls the resonance of the sound - short notes are "killed" by closing the cabaça while long notes are allowed to ring in an open cabaça. When the berimbau is used in popular music, even more variation is used.
