T. K. Murthy is an Indian mridangam player. He was born on 13 August 1924 to Thanu Bhagavathar and Annapoorani. At the age of eight, he was guided to Tanjore Vaidyanatha Iyer. Vaidyanatha Iyer, took Murthy to Tanjore, where Palghat Mani Iyer and Thambuswami, brother of T. M. Thiagarajan, were also undergoing training.
Murthy was more than a biological son, to his Guru Vaidyanatha Iyer and his wife. They showered love and care on him. Thus, Murthy found his mentor in Vaidyanatha Iyer, to whom he still offers ceremonial oblations and rites as a true son.
Murthy made his debut at the age of eleven, at Coimbatore in a concert of Musiri Subramania Iyer with Karur Chinnaswami Iyer on violin and Tanjore Vaidyanatha Iyer on mridangam. That was the start of an illustrious career in which he accompanied in more than 15,000 concerts so far.
He has accompanied eminent artists over five generations, including Harikesanallur Muthiah Bhagavatar, Ariyakudi Ramanuja Iyengar, Chembai Vaidhyanatha Bagavathar, Semmangudi Srinivasa Iyer, M. S.
