Material: All-Natural materials, Sustainable Wild Banana Tree Seeds, Hard Gourd Skin Base. Tone: Provides excellent rhythmic accompaniment and color. Hand-Woven in Brazil this caxixi is used primarily with Berimbau. The combination of the red seeds striking the gourd-skin base, produces a sharp, high-pitched tone, contrasting the softer, deeper pitch when the seeds strike a woven body. The shape of the handle is designed to be easily played in hand when playing the Berimbau, the traditional Brazilian wooden musical bow.
