Bhoothapandi Annavi Chidambaranathan (13 October 1924 - 31 August 2007) was an Indian film score composer and musician who worked mainly in Malayalam films. Hailing from a family of reputed musicians from Nagercoil in Kanyakumari district of Travancore (now Tamil Nadu, India), Chidambaranathan took early lessons in mridangam and Carnatic vocal from his father, B. K. Arunachalam Annavi. He also took training for sometime under Muttiah Bhagavathar and used to play mridangam for him at his concerts. He then learnt the violin first under Nagamani Marthanda Nadar and then for seven years under the Kumbakonam Rajamanickam Pillai. Chidmabranathan was noticed by music director C. N. Pandurangan, when he was playing violin at a concert of M. M. Dandapani Desikar.
