The tar is the most widely used plucked instrument in Iran today. It is a fretted lute with six strings, five of steel and one of brass. It has a long neck and a double bellied sound box, over which is streched a thin sheep skin membrane. The tunings of the strings are changed according to the dastgah that is being played, and the twenty six frets are movable. Finally, the strings are plucked with a plectrum.
