Pandit Vishnu Narayan Bhatkhande (10 August 1860 – 19 September 1936) was an Indian musicologist who wrote the first modern treatise on Hindustani classical music, an art which had been propagated for centuries mostly through oral traditions.
While not a professional musician himself, his father, who worked for an affluent businessman, ensured that Vishnu Narayan and his siblings received an education in classical music.
After turning fifteen, Bhatkhande became a student of the sitar and subsequently began studying Sanskrit texts that dealt with music theory.
He studied at the Mandali for six years and learned a variety of compositions in both khayal and dhrupad forms under musicians such as Shri Raojibua Belbagkar and Ustad Ali Hussain.
He established contact with stalwarts such as Tiruvottriyur Tyagayyar and Tachur Singaracharya in Madras, Poochi Srinivasa Iyengar in Ramanathapuram and Subbarama Dikshitar in Ettayapuram but the language barrier made these interactions less fruitful than he expected.
Notes from a journal maintained of his time there were later published as Meri Dakshin Bharat Ki Sangeet Yatra (My Musical Journey in Southern India).
[5] While his conversations with exponents of Carnatic music weren't very successful, Bhatkhande procured two valuable manuscripts on the art: the Chaturdandiprakashika by Venkatamakhin and the Svaramelakalanidhi of Ramamatya, both treatises that sought to classify ragas.
The two works along with others and his observations from his travels in North India enabled Bhatkhande to classify Hindustani ragas using a system of ten, much like the melakartas of the Carnatic style.
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.
He also started the tradition of the All India Music Conferences to provide a common platform for discussion between Hindustani and Carnatic classical musicians.
