Manjapara Devesan Ramanathan (May 20, 1923 – April 27, 1984) known as MDR was a Carnatic music composer and vocalist.
Manjapara Devesan Ramanathan was born in Manjapara, Palakkad District, Madras Province (now Kerala), India on 20 May 1923. His father Devesa Bhagavathar was a music teacher by profession. Ramanathan did his schooling in Palakkad and graduated with a BSc degree in Physics from Victoria College, Palakkad. On completion of his studies, he traveled to Madras along with his father to improve his musical talents.
During the same time, Rukmini Devi Arundale initiated a new course on Sangeeta Siromani at Kalakshetra. Ramanathan auditioned for the course and was the only student to be selected for the first batch commencing in 1944. Soon, he emerged as Tiger Varadachariar's favorite and was his closest disciple when the latter died in 1950.
After his graduation, Ramanathan continued as an assistant to his guru and later became Professor of Music at Kalakshetra. He also served as the Principal of the College of Fine Arts at Kalakshetra.
Ramanathan was known for his unique style of singing. In addition to having an extremely deep, booming voice, he rendered songs at an extremely slow pace, thereby allowing ample time for the listener to catch every phrase of a composition and gauge its meaning. He also sang with adequate bhava or expression. Ramanathan has sung in most Carnatic music ragas such as Sahana, Sri, Anandabhairavi, Reethigowla and Yadukula Kambhoji. Other favorite ragas of his include Kedaram, Kambhoji and Hamsadhwani. As he himself once admitted, his Vilambita Kaala Gaanam renderings during Kathakali dances had influenced his music and style of singing. Though Ramanathan is identified with his "trademark" slow pace of singing, he did include a few relatively brisk renderings in his concerts off and on.
