The Indian santoor is accepted as the oldest known string instrument of India. While it had originally been part of the classical music in Persia, in India the santoor was a highland folk instrument. The Indian santoor is a flat shaped instrument in the form of a trapezoid. Two light wooden hammers are included to play along the metal strings providing an exotic sound.
The santoor is made almost completely out of wood with steel strings. It is a very delicate instrument that is incredibly sensitive to even light strokes and glides.
