The Güiro is a Latin American instrument made out of a hollow gourd or sometimes made of wood or plastic. The body of the güiro has a grooved surface on top. There are large holes in the bottom so the player may grip the instrument. One end of the instrument may also have an opening.
The player scrapes across the grooved surface with a stick (wood or plastic to match the body) in a rhythmic patterns to determine the length of the sounds.
