Bismillah Khan (born Qumaruddin Khan, 21 March 1916 – 21 August 2006), often referred to by the title Ustad, was an Indian musician credited with popularizing the shehnai, a reeded woodwind instrument. He played it with such expressive virtuosity that he became a leading Hindustani classical music artist. His name was indelibly linked with the woodwind instrument. While the shehnai had long held importance as a folk instrument played primarily schooled in traditional ceremonies, Khan is credited with elevating its status and bringing it to the concert stage.
