Iranians consider Tar the "sultan of instruments." Its present form was developed in 18th century and has been the choice of Persian classical masters since. It has a double-bowl body of mulberry or walnut wood with a lambskin face. The fingerboard has 28 frets and the three double strings are played with a plectrum made of brass and honeycomb.
The long and narrow neck has a flat fingerboard running level to the membrane and ends in an elaborate box with six wooden pegs of different dimensions. It has three courses of double "singing" strings (each pair tuned in unison: the first two courses in plain steel, the third in wound copper), that are tuned in fourths (C, G, C) plus one "flying" bass string (wound in copper and tuned in G (an octave lower than the singing middle course) that runs outside the fingerboard and passes over an extension of the nut.
There are also two pairs of shorter sympathetic strings that run under the bass and over two small copper bridges about midway the upper side of the fingerboard: their tuning is variable according to the piece to be played and with the performer's tastes.
Tar is a plucking instrument with 3 sets of strings.
