Castanets are percussion instruments traditionally made of wood or plastic, consisting of two hinged shells that are clicked together. They are commonly used in various forms of music and dance, particularly in Flamenco, a passionate Spanish dance style. The player holds one castanet in each hand and produces sound by snapping them together. These instruments have a rich history and are often associated with Spanish culture. Castanets can vary in size and shape, affecting their sound and playability. They are typically played by dancers to enhance the rhythm of the performance, adding a lively and dynamic element to the music.
