The quinto (literally fifth in Spanish) is the smallest and highest pitched type of conga drum. It is used as the lead drum in Cuban rumba styles such as guaguancó, yambú, columbia and guarapachangueo, and it is also present in congas de comparsa. Quinto phrases are played in both triple-pulse (12/8, 6/8) and duple-pulse (4/4, 2/2) structures. In columbia, triple pulse is the primary structure and duple pulse is secondary. In yambú and guaguancó duple-pulse is primary and triple-pulse is secondary.
