The sitar (Hini: सितार, Urdu: ستار, Persian: سی تار ) is a plucked stringed instrument. It uses sympathetic strings along with a long hollow neck and a gourd resonating chamber to produce a very rich sound with complex harmonic resonance. Predominantly used in Hindustani classical, sitar has been ubiquitous in Hindustani classical music since the Middle Ages. This instrument is used throughout the Indian subcontinent.
