Chembai Vaidyanatha Bhagavatar(born Vaidyanatha Iyer, 1 September 1896 – 16 October 1974) was an Indian Carnatic music singer from Palakkad. Known by his village name Chembai, or simply as Bhagavatar, he was born to Anantha Bhagavatar and Parvati Ammal in 1896, into a Tamil Brahmin family in Perakkool Madom (Parvati Ammal’s birth home), adjacent to Lokanarkavunear Vatakara on Janmashtami day. He lived here until he was five years old. The family later shifted to Palakkad. Chembai was noted for his powerful voice and majestic style^[3] of singing. His first public performance was in 1904, when he was nine. A recipient of several titles and honours (including the Madras Music Academy’s Sangeetha Kalanidhi in 1951), he was known for his encouragement of upcoming musicians and ability to spot new talent. He was responsible for popularising compositions like Rakshamam Saranagatam and Pavana Guru, among others. The music critic ‘Aeolus’ described him as “the musician who has meant the most to Carnatic Music in the first fifty years of the 20th century.” His prominent disciples include Chembai Narayana Bhagavathar, Mangu Thampuran, Guruvayur Ponnammal, T. V. Gopalakrishnan, V. V. Subramaniam, P. Leela, K. G. Jayan, K. G. Vijayan, K. J. Yesudas, Kudumaru Venkataraman and Babu Parameswaran, among others. He also mentored many young accompanists, including Palghat Mani Iyer, Lalgudi Jayaraman, M. S. Gopalakrishnan, T. N. Krishnan, Palani Subramaniam Pillai and L. Subramaniam. Memorial music festivals have been held in his honour annually since his death in 1974, the most important being the annually celebrated Chembai Sangeetholsavam.
