Answer:
Castanets
•Have you ever watched Flamenco dancers at a Spanish or tapas restaurant and wondered about the little percussion instruments in their hands? These are called castanets.
•Castanets are popular handheld instruments that have been used in Mediterranean music styles for centuries.
They’re used in just about every music style globally, but they gained popularity in regions such as Greece, Turkey, and Italy.
Eventually, they made their way to Spain. Today, they’re Spain’s national instrument.
Most people will recognize the traditional flamenco castanet, which looks different than other types of castanets. That’s because modern castanet was developed in Spain.
•Castanets are usually made out of castana wood, though they can also be made out of metal. The instrument consists of two cups with curved dips on one side.
These cups are manufactured in a specific way to create a unique sound. They’re drilled so one cup is a higher pitch than the other. This is why this little instrument gives off such a distinct sound.
