Santur

The santur is a three-octave wooden-hammered dulcimer with seventy-two strings, which are arranged on adjustable tuning pegs in eighteen quadruple sets, nine (bronze) in the low register, and nine (steel) in the middle register. The santur can be made from various kinds of wood (walnut, rosewood, betel palm, etc.) depending on the desired sound quality. The front and the back of the instrument are connected by sound posts, the positions of which play an important role in the sound quality of the instrument. Versions of the santur were known in the ancient Assyrian and Sassanian cultures.
