Berimbau sound

The berimbau, as played for capoeira, basically has three sounds: the open string sound, the high sound, and the buzz sound.

• In playing the buzz sound, one holds easily the gourd closed against one's belly, while touching the string with the dobrão. A muted "tch" sound emerges.

• To play the open string sound, one strikes the string less than an inch up from the gourd string, with the bow balanced on the little finger so that the gourd is opened. One can grossly tune the open sound, by loosening the arame, and by sliding the gourd a little up or down from the place where the sound is best.

• To produce the high sound, one must hold the bow in the same way, gourd opened, and forcefully press the dobrão on the string. The sound differs from the low sound in tone and in timbre. Old recordings and musicians report that the difference in tone used to be about 1 tone (the interval from C to D). One can press the dobrão away enough from the gourd for this only if the bow is about 4 feet (1.2 m) to 4 feet 2 inches (122 to 127 cm); that was the length of the bows in the 1940s and 1950s. Today, many berimbaus are overgrown to 5 feet (150 cm) , and tuning options are limited in berimbau ensembles.

Other sounds may appear in a berimbau performance, but only these define capoeira's rhythmic patterns (except Iuna).

Closing and opening the gourd while the string resounds produces a wah-wah effects, which depends on how large the gourd opening is. Whether this effect is desirable or not is a matter of controversy. Pressing the dobrão after striking the string is a widely used technique; so is closing neatly the gourd while the string resounds to shut off the sound. A specific toque requires the open string sound with closed gourd. Musicians use whatever sound they may get out of the string. It is not often considered bad practice to strike other parts of the instrument. As with most aspects of playing the berimbau, the names of the techniques differ from teacher to teacher. Most teachers, and most students, worry more about producing a nice sound than about naming the individual sounds.

Of course, the strength (velocity, accent) with which one lets the vaqueta hit the string is paramount to rhythm quality. The open sound is naturally stronger (meaning that, for a constant-strength strike, the other two sound weaker), but the musician may decide which strikes to stress. Also, the sound tone shifts a little with the strength of the strike, and some sophisticated toques make use of this.
