The güiro is a percussion instrument consisting of an open-ended, hollow gourd with parallel notches cut in one side. It is played by rubbing a wooden stick along the notches to produce a ratchet-like sound. The güiro is commonly used in Latin-American music, and plays a key role in the typical cumbia rhythm section. Güiro is also another term for an agbe or shekere as well as the ensemble and rhythm used when playing this instrument.
