He was born on 12 June 1912 at Pazhayanur, then in Tiruvilvamala Taluk, in Palghat District, to Sesham Bhagavatar and Aanandaambaal as their second son. Mani was named Ramaswami at birth— after his grandfather who was a school teacher besides being a good singer. Mani Iyer learnt his music from his parents in his native Pazhayyanur. His maiden public performance was at the age of 10 at a harikatha discourses by Sivaramakrishna Bhagavathar. The mridangam player who was supposed to play had failed to turn up and Mani Iyer substituted. Later he caught the eye of Thanjavur Vaidyanatha Iyer who taught him the intricacies that invested his recitals with remarkable purity. Mani Iyer came into prominence in 1924, after accompanying Chembai Vaidyanatha Bhaagavathar in a music concert at Jagannatha Bhaktha Sabha in Madras.
Career
Mani Iyer accompanied all the leading vocal artists of his era. He was also the guru for later mridangam players such as Late Palghat R. Raghu, Late Mavelikkara Velukkutty Nair, Umayalpuram K. Sivaraman, Thanjavur R.Ramadas, Kamalakar Rao, Late G. Harishankar,etc. Before Mani Iyer’s arrival in the music scene, the three mridangists Nagercoil S.Ganesa Iyer, Alaganambi Pillai and Dakshinamurthy Pillai, dominated the percussion scene. The way in which Mani Iyer played changed the style of mridangam playing from just keeping beat for the main artist's music to being an instrument in its own right. A comment from Y. G. Doraisamy: "It was Mani Iyer who started the now prevalent trend of the mridangam, not just keeping the time with tekkas and moras, but actively accompanying the musical phrasing, so as to be a rhythmic running commentary, reproducing on the drum all the subtleties and rhythmic complexities of the musical composition." Palghat R. Raghu, a disciple of Mani Iyer, describes his guru as a genius in that he showed music followers the manner of blending with the music of the main artist in handling the kritis of every conceivable mood and tempo. By his consistent excellence he could raise the concert to thrilling heights.
