Muthiah was born on 15 November 1877, in Harikesanallur, a small village in the Tirunelveli district of British India, into an affluent Tamil Brahmin family.
He lost his father at the young age of six years, when his maternal uncle M. Lakshmana Suri took over the responsibility for his education, initiating Muthiah into Sanskrit and Vedic studies.
[1] However, the love of music that had been implanted in him led Muthiah to leave his hometown of Harikesanallur, Tamil Nadu when he was only ten years in search of a teacher.
He found the gifted teacher Padinaindumandapa Sambasiva Iyer at Tiruvarur, who recognised Muthiah's talent for music.
He has to his credit almost 400 musical compositions, the largest among the post-Trinity composers, that included many different types of Varnams as well as Kritis and Thillanas.
In 1934, Muthiah composed music for Tamil Nadu Talkies then owned by S. Soundararaja for their Lavakusa, a film based on the Uttara Ramayana.
T. N. Seshagopalan, who was taught by Ramanathapuram Sankara Sivam, a disciple of Muthiah Bhagavathar, said "He was also the first to introduce the practice of nagaswara vidwans playing during the puja time at the Thiruvananthapuram temple."
Later he was invited to the court of Travancore by the Maharaja Mulam Tirunal where he studied Swatitirunal kritis and wrote the book Sangeeta Kalpadruma, which won him an honorary doctorate.
