music across 10 musical scales, called thaats. Though the thaats do not encompass all possible ragas, they do cover the vast majority and are a key contribution to Indian musical theory. The thaat structure corresponds to the melakarta system of raga arrangement in Carnatic music, the south Indian variety of Indian classical music. Bhatkhande wrote all of his works under one of the two pseudonyms, Vishnu Sharma and Chaturpandit. Institutions Bhatkhande started schools and colleges in India for systematic teaching of Hindustani music. In 1916, he reorganized the Baroda state music school, and later, with the help of the Maharaja of Gwalior, established the Madhav Music College in Gwalior. In 1926, Rai Umanath Bali and his nephew Dr. Rai Rajeshwar Bali, then education minister of United Provinces, established Marris College of Music in Lucknow, Bhatkhande preparing the course material. The college was later renamed Bhatkhande College of Hindustani Music, and is now known as Bhatkhande Music Institute (Deemed University). Preparation of that course material was a landmark achievement of Bhatkhande since musical knowledge used to be passed on orally in earlier times from Gurus and Ustads to their disciples. Bhatkhande prepared the Hindustani Sangeet Kramik Pustak Maalika as a series of textbooks. He also started the tradition of the All India Music Conferences to provide a common platform for discussion between Hindustani and Carnatic classical musicians. Death Bhatkhande suffered paralysis and a thigh fracture in 1933. He died on 19 September 1936, during Ganeshotsav in Mumbai.
