The sitar is a plucked stringed instrument, originating from the Indian subcontinent, used in Hindustani classical music. The instrument was invented in medieval India, flourished in the 18th century, and arrived at its present form in 19th-century India. Khusrau Khan, an 18th-century figure of the Mughal Empire has been identified by modern scholarship as the inventor of the sitar. According to most historians, he developed the sitar from the setar, an Iranian instrument of Abbasid or Safavid origin. Another view supported by a minority of scholars is that Khusrau Khan developed it from Veena.

Plucked string instruments are a subcategory of string instruments that are played by plucking the strings. Plucking is a way of pulling and releasing the string in such a way as to give it an impulse that causes the string to vibrate. Plucking can be done with either a finger or a plectrum.
