It is an ancient Indian musical string instrument. The santoor is a trapezoid-shaped hammered dulcimer often made of walnut, with seventy two strings. The special-shaped mallets (mezrab) are lightweight and are held between the index and middle fingers. A typical santoor has two sets of bridges, providing a range of three octaves.
It is somewhat like trapezium shape .Santoor in western parts is mainly found with 72 strings. However in India it can have as many as 92 strings. The strings, grouped in units of 3 or 4, are tied on nails or pins on the left side of the instrument and are stretched over the sound board on top of the bridges to the right side. On the right side there are steel tuning pegs or tuning pins, as they are commonly known, that allows tuning each unit of strings to a desired musical note or a frequency or a pitch.
It is played by two bows by placing santoor on lap in asana position.
