It is one of the ancient Iranian classical instruments. The oldest sample instrument still remaining is comprised of a dual box and the surface of the lower one is covered by a hide. The produced tune is first transferred from the lower box to the upper one, from where it is broadcast through two wide openings. This part of the instrument is very interesting from the scientific point of view, since a second box has been added on its surface in order to amplify the tune. This makes the instrument much richer in producing a great variety of tunes. It has 4-6 cords, which similar to conventional Kamancheh, have been extended on a wooden box. It is played by a bow of particular shape, while the musician simultaneously creates the desired tune by plucking the cords by his/her left hand. The instrument's box is made of berry wood.
