Bongo drums produce relatively high-pitched sounds compared to conga drums, and should be held behind the knees with the larger drum on the right when right-handed. It is most often played by hand and is especially associated in Cuban music with a steady pattern or ostinato of eighth-notes known as the martillo or “hammer”.They are traditionally played by striking the edge of the drumheads with the fingers and palms. The glissando used with bong de monte is done by rubbing the third finger, supported by the thumb, across the head of the drum. The finger is sometimes moistened with saliva, or sweat before rubbing it across the head. When used in art music compositions they are usually struck with drum sticks. These drums can also be played on a stand, as is the case with concert orchestras and bands.
