"Annapurna Devi became a very accomplished surbahar (bass sitar) player of the Maihar gharana (school) within a few years of starting to take music lessons from her father Alauddin Khan. She started guiding many of her father's disciples, including Nikhil Banerjee and Bahadur Khan, in classical music as well as in the techniques and intricacies of instrumental performances. In 1941, age 14, she married one of her father's talented students, Ravi Shankar. She converted to Hinduism upon marriage.
In the 1950s, Ravi Shankar and Annapurna Devi performed duets in Delhi and Calcutta, principally at the college of her brother, Ali Akbar Khan. But later, Shankar started getting insecure, since she used to be applauded in concerts more than he was, and she thereafter decided not to perform publicly.
Devi and Shankar's son, Shubhendra Shankar (1942–1992), (or "Subho", as he was popularly known) received rigorous training in sitar under her tutelage, until his father chose to interrupt his musical talim or training and took him to the United States. Shubhendra died at an early age in 1992, after a marriage and the birth of three children. Shubhendra did not have a solo career in classical music, but did for a period accompany his illustrious father Ravi Shankar in concerts in the USA and abroad."
