The santoor is called the ‘shata tantra veena’ — the hundred-stringed lute. It produces a variety of lively tonal effects reminiscent of the piano or harp. The santoor is played with a pair of curved sticks made of walnut wood, and consists of a trapezoid-shaped sound body with twenty-five to twenty-nine bridges on each side and four strings per bridge. Two strings are tuned to the same pitch.
