tar

The Persian tar is carved from a block of mulberry wood and has a deep, curved body with two bulges shaped like a figure 8. The upper surface is shaped like two hearts of different sizes, joined at the points. The sound box consists of two parts. The  small  part is called

Naghaareh and the large part is called  Kaasseh (that  means bowl (sound-box)). The sound  box is covered with lambskin. On the lower skin, a horn bridge supports six metal strings in three courses. The long fingerboard has twenty-two to twenty-eight movable gut frets. The strings are plucked with a brass plectrum coated on one side in wax. Its range is about two and a half octaves.
