Castanets are a percussion instrument made up of two cup-shaped wooden clappers attached at one end by string or elastic. The castanets are held in the hands, usually one in each hand, with one side resting on the palm and the other side supported by the fingers which are lightly closed in on the hand. They are played by opening and closing the hand, clapping the two wooden clappers together rhythmically. They are particularly associated with Spanish singers and dancers. In orchestral music, the castanets are usually mounted on a handle which is then shaken to produce the sound.
