The bombo criollo, or simply bombo, is a family of Latin American drums derived from the European bass drum (also called in Spanish bombo). These drums are of smaller dimensions than the orchestral bass drum, and their frame can be made of wood or steel. They can be held vertically or diagonally on the body or a stand. The specific make of the instrument depends on the regional tradition. In Argentina, the bombo criollo is called bombo legüero.
