The swarmandal (also known as Sur-mandal) is an Indian harp/zither that is today most commonly used as an accompanying instrument for vocal Hindustani Classical music. The name combines swara (notes) and mandal (group), representing its ability to produce a large number of notes. Swarmandals measure from twenty-four to thirty inches in length and twelve to fifteen inches in width. It is also similar to an instrument from Iran, and has been used for many generations, dating back to the Mughal era. Some of the vocalists who have used this instrument extensively are Ustad Bade Ghulam Ali Khan, Ustad Salamat Ali Khan, Pandit Jasraj, Kishori Amonkar, Ustad Rashid Khan and Pandit Ajoy Chakravarty.
