Construction of Rebab
The Rebab has a piece of hollow wood at the top and a hollow circular wooden belly covered with a sheep skin at the bottom. It has a pear-shaped resonator covered with parchment. There is neck and a short fingerboard without frets. There are two bridges, one in the middle and the other at the tip. The two bridges support six gut strings which are manipulated by six pegs at the top. Some Rebabs have a wooden Toomba (gourd) at the top. It is played with a triangular wooden plectrum. Its sound resembles the human voice and it can play some Gamaks.
Another Rebab, also plucked, is the one with a waist. This instrument, now found only in Kashmir, has a body not with a smooth outline, but with two constructions, one on either side. Besides, the body is deep and extends into a fingerboard. The resonator is parchment covered and bears a thin bridge. There are six strings for playing the melody, corresponding to which are six pegs in the peg box. Usually there are about eleven sympathetic strings Tarab and one Chikari used as the drone. The instrument is held across the body of the squatting musician and played with a wooden plectrum. A very interesting feature is a set of four guts tied across the fingerboard, looking like frets. They are loose enough to be moved, but also fairly tightly tied.
