güiro

The güiro is a Latin-American percussion instrument consisting of an open-ended, hollow gourd with parallel notches cut in one side. It is played by rubbing a stick or tines along the notches to produce a ratchet-like sound.
The güiro is commonly used in Puerto Rican and other Latin-American music, and plays a key role in the typical rhythm section of important genres like cumbia and son. Playing the güiro usually requires both long and short sounds, made by scraping up and down in long or short strokes.
The güiro, like the maracas, is often played by a singer. Another type of güiro, commonly found in Brazil, is the reco-reco, is made of a cylindrical metal box that encases two or three steel springs. These are stretched over a lid, against which a metal stick is rubbed.
