The ganza, or shaker, is used in practically all Brazilian rhythms. The instrument consists of a brushed aluminium cylinder, filled with small metal balls that produce a rustling sound. The pitch and volume of this sound depend on the dimensions of the ganza.
The ganza is played by shaking it in a way that forms the distinctive samba groove with a good sense of timing. Because of its small size and light weight, the ganza is the perfect instrument for dancing and playing at the same time.
