The mandar baar is very similar to the esraj in construction but the finger-board and the body are bigger in size, being about four feet long. Thick strings of gut are used which give a deep, rich tone somewhat like that of the Western violin cello.
To play the instrument the performer sits on a low stool. The instrument is placed in front of him on the floor, the top of the instrument leaning against his left shoulder. The mandar bahar is a rare instru¬ment found mostly in Bengal. It is now being used in the modern Indian orches¬tra for producing bass notes in the lower octaves.
