Castanets are a percussion musical instrument, made up of two pieces of wood joined by a cord. Spain is the country that has best preserved castanets, developing their use, being one of the national instruments, like the Spanish, classical or flamenco guitar. Widely used in typical or traditional dances. Traditionally, the castanet is attached to the thumb with the cord that joins its two halves, which are suspended between the palm of the hand and the fingers. To make it sound, both halves are clicked together with the movement of the fingers and a twist of the wrist. The tones of the pairs are different, the lowest is called male and the highest female. The high castanet is placed in the right hand and the low one in the left hand. If you don't know how to differentiate the sound, you can distinguish it because the right castanet has a notch in the ear, (upper part)
