Vishnu Narayan Bhatkhande, Indian singer and musicologist (d. 1936)
Pandit Vishnu Narayan Bhatkhande (Har ranng/ Chatur Pandit) (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. During those earlier times, the art had undergone several changes, rendering the raga grammar documented in scant old outdated texts.Ragas used to be classified into Raga (male), Ragini (female), and Putra (children). Bhatkhande reclassified them into the currently used thaat system. He noted that several ragas did not conform to their description in ancient Sanskrit texts. He explained the ragas in an easy-to-understand language and composed several bandishes which explained the grammar of the ragas.
