Claves (Spanish pronunciation: ['klaβes],, Anglicized pronunciation: CLA(H)-vays) are a percussion instrument (idiophone), consisting of a pair of short (about 20–30 cm (7.9–11.8 in), thick dowels. Traditionally they are made of wood, typically rosewood, ebony or grenadilla. In modern times they are also made of fibreglass or plastics.When struck they produce a bright clicking noise.
