He was 70 and is survived by his wife Chitra Singh.
Padma Bhushan Jagjit Singh was regarded as one of the greatest singers India has ever produced. He belonged to the Agra Gharana of Indian classical music.
Born in Sri Ganganagar in Rajasthan, his parents wanted him to be an IAS officer but music was his calling. He left his studies prematurely at the Kurukshetra University and went to Mumbai in 1965 to try his luck as a singer/composer. Jagjit Singh gained acclaim together with his wife in the 1970s and 1980s, as the first ever successful duo act (husband-wife) in the history of recorded Indian music.
He has sung in Punjabi, Hindi, Urdu, Bengali, Gujarati, Sindhi and Nepali languages.
