Santur refers to music centered on the santur (or santoor), a trapezoidal hammered dulcimer whose strings are struck with light wooden mallets. Originating in Persia (modern Iran), the instrument spread through Mesopotamia and the wider Middle East, later inspiring related dulcimers across Europe and Asia. In Iranian classical music, the santur is tuned to the modal dastgāh system and features shimmering tremolos (riz), delicate grace notes, and agile, dance-like passages (especially in chahārmezrāb and reng). In Iraq and the Levant it participates in maqām traditions, while in the Indian subcontinent—especially through the Kashmiri santoor—it was adapted to the Hindustani raga system and re-engineered with more strings and different bridges for sustained melodic development. The timbre is glassy and bell-like but warm, capable of luminous arpeggios, rippling rolls, sharply articulated rhythms, and intricate ornamentation. Modern performers also bring the santur into jazz, film music, pop, and electronic fusion.
