Khan learnt music from his father, Ashiq Ali Khan, who had learned sitar from the 19th century player Barkatullah Khan, a descendant of Masit Sen of Delhi, the inventor of the Masitkhani gat His name became synonymous with the Senia style although he may actually have practised an even more austere style than his predecessors in the gharana. He eschewed much of the ornamentation of modern sitar technique, and embraced a clean, pure sound. His alap was constructed along the lines of a dhrupad alap, and his jod and jhala derived a lot from rudra vina technique. Oddly enough, in spite of being a musical descendant of Masit Sen, he rarely played Masitkhani gats in public, and none of the commercially available examples of his music includes one. He opted to play the faster Rezakhani gats instead, feeling that playing Masitkhani gats to an undiscerning audience would cause them to be devalued. At first a court musician at Jaunpur, Mushtaq Ali left the court to pursue an independent career. He started playing for All India Radio in 1929, and performed at the 1931 Sangeet Sammelan in Allahabad. For all of the 1940s and most of the 1950s he was considered the most prominent sitar player in India, following the demise of Enayat Khan of the Etawah Gharana, and prior to the rise of the young Nikhil Banerjee, Ravi Shankar and Vilayat Khan in the mid-1950s. In 1968 he won the Sangeet Natak Akademi Award, the highest Indian recognition given to practising artists, given by Sangeet Natak Akademi, India's National Academy of Music, Dance and Drama. Being a purist, Khan-Saheb refused to yield to shifting popular tastes and to adopt the innovations introduced by Ravi Shankar on one hand and Vilayat Khan on the other, which led to a gradual decline in his popularity. At the time of his death he was known as a "musicians' musician". Many of India's best known musicians expressed their appreciation of the purity of his style and musicality in a book published in Delhi after his death
Instruments
Mushtaq Ali Khan belonged to the Senia Gharana. He was the only surbahar player of India who used to play the been-ang with three mizrabs and that too, with the pakhawaj as an accompanying instrument only in pure dhrupad style. In a rare exclusive interview in the Daily Telegraph on 13 July 1985, Khan Sahab narrated the history of this instrument with historical references in which he has cleared the myth of this instrument. Khan Sahab had his lineage with fifth vani, called Dhandvani named after one of the forefathers. The famous dhrupadiya of Shah Jahans Court, Nayak Dhundhu. It is also called Rasal Vani for its beauty. He said, "... two of my ancestors, Jaggu Khan and Makku Khan. Since Makku Khan was childless, he adopted Waras Ali Khan a great name who learnt the art of playing Been from Bade Mohammed Khan. When my father Ashiq Ali Khan was six years old, my grand father Sadaq Ali Khan, son of Jaggu Khan died so his uncle Waras Ali Khan taught him all intricacies of Beena on the surbahar. That is why we play Surbahar with three Mezrabs. The Surbahar was originally designed to felicitate the playing of Alap. Those days Alap was the exclusive prerogative of the Beenkar. Ghulam Muhammed Khan and his son Sajjad Mohammed Khan the great SurBahar players used to stay at Calcutta in the earliest part of the 20th century and taught many renowned players, including Imdad Khan and Jnanoda Mukherjee. In this instrument two angas played are alap and talparan and that is why the knowledge of pakhawaj is essential to play the Talparan ...".

Khan's (late) activities
A follower of rasal vani, Khan Sahab was the only surbahar player who maintained the purity of the rasal vani.
