The shak-shak (or chak-chak) is a hand-held shaken percussive idiophone. They are played in Barbados, Grenada, Montserrat, and elsewhere in the Caribbean and Latin American musical traditions. The term shak-shak is believed to be onomatopoeic in origin, derived from the characteristic sound the instrument produces when shaken.
