Khan, after years of rigorous training, gave his debut performance at a music conference in Allahabad in 1936, at the age of 13. Three years later, in December 1939, he accompanied Ravi Shankar on the sarod during the latter's debut performance at the same conference; this was the first of many "jugalbandis" (duets) between the two musicians. In 1938 Khan gave his first recital on All India Radio (AIR), Bombay (accompanied on the tabla by Alla Rakha), and starting in January 1940, he gave monthly performances on AIR, Lucknow. Finally in 1944, both Shankar and Khan left Maihar to start their professional careers as musicians; Shankar went to Bombay, while Khan became the youngest Music Director for AIR, Lucknow, and was responsible for solo performances and composing for the radio orchestra.
