Ganzá
The ganzá is a Brazilian rattle used as a percussion instrument, especially in samba music.
The ganzá is cylindrically shaped, and can be either a hand-woven basket or a metal canister which is filled with beads, metal balls, pebbles, or other similar items. Those made from metal produce a particularly loud sound. They are usually used to play a rhythm underneath the rest of the band.
It is usually included in the Brazilian Samba as an undertone.
The ganzá is classified as an indirectly struck idiophone.
