Santur (Persian: سنتور, also santūr, santour, santoor) is a Perisan hammered dulcimer (modern day Iran), consisting of a trapezoidal box with horizontal strings, played with oval shaped featherweight mallets known as mezrab. The Iranian classical santur has 72 strings of brass or copper and stainless steel, 18 sets of four tuned in unison, with two rows of bridges providing a range of three octaves.
A variant of the instrument is played in Turkey. Similar types of hammered dulcimer are found widely spread in Europe and Asia; the Indian santoor is wider, more rectangular and has more strings.
The term santur is of unclear etymology, though theories include the meaning "one hundred strings" in Persian, or derivation from the Greek term psalterion.
Two rows of nine bridges called kharak divides the santur into three positions. Over each bridge crosses four strings spanning horizontally across the right and left side of the instrument. The Iranian santur is primarily tuned to a variety of different diatonic scales utilizing quarter tones, which are used in the twelve dastgahs (modes) of Iranian classical music called the radif.
