Castanets

These are castanets.

Each pair of castanets is played with one hand. The two pairs are not alike: one pair is "female" and sounds higher, the other is the "male" pair and sounds lower.

Who invented the castanets?

The castanets are a percussion instrument.

From the 256 wooden pipes flow the sounds of an orchestra with viola, bass, saxophone, trumpet, trombone, violin, flute, flageolet, and piccolo. The organ also has a glockenspiel, castanets, a cymbal, and snare and bass drums.
