The rebab is a musical instrument from the Middle East. It is a very old instrument, and is probably the origin of the medieval rebec. It is a string instrument and is played by bowing or plucking the strings. It has a body made out of a solid piece of wood, with straight sides and a round back. The belly of the rebab is made of skin. The pegs used to tune the strings are like those on a violin, and are pushed into holes on the side of the peg box. The peg box is made from a separate piece of wood.
