She was the daughter of Allaudin Khan, the greatest Indian classical musician of his age; her brother was Ali Akbar Khan and her first husband was Ravi Shankar. Her specialty was the surbahar (bass sitar), and when she and her husband performed together, audiences were even more impressed by her than by him. About a decade into that (very stormy) marriage, she stopped performing in public entirely and became (though something of a recluse) one of India’s most revered classical music teachers.
