This percussion instrument, of Afro-Peruvian origins, is used in most coastal variations of the marinera, as well as música criolla (Creole) and música negra (Afro-Peruvian) genres in general. The instrument is crafted from a wooden box which features a soundhole at the back.
The musician sits on top and slaps on the front surface with the palms of his hands. Although of simple appearance, the instrument has built up a following outside Peru, including its recent incorporation into flamenco.
