Born in a family of great musicians to Sangeetha Bhooshanam Sri Embar Sadagopan, Kannan took to playing the violin at the age of six. His initial training in Carnatic music was with Sri Subbanna Bhagavathar and Sri
Vittal Ramamurthy. In 1986 he received a talent scholarship from the Government of India and earned a place under the mentorship of Kum.
A. Kanyakumari. Shortly thereafter he received the Yuva Kala Bharathi from Bharat Kalachar and the ‘Best Violinist Award’ from the
Madras Music Academy for eight consecutive years. Over the course of his Carnatic career he has accompanied many leading artists such as T. V. Sankaranarayanan,
Trichur Ramachandran,
T. N. Seshagopalan,
Sudha Raghunathan,
Kadri Gopalnath,
P. Unnikrishnan,
Bombay Jayashree and
S. Sowmya. One of Kannan's prodigal accomplishments was the introduction of the
silent violin to Carnatic Music in 2001. In August 2006, he played the silent violin at Puttaparthi in the presence of Bhagawan Sri
Satya Sai Baba with the musicians of the HeArtBeat Ensemble. On 14 July 2011, he played at a concert that was organised to raise funds for the Sankalp Trust, the open school and learning centre for special children, at the Mutha Venkata Subba Rao Concert Hall. ==Film music career==
