Narasimhan Ravikiran (born 12 February 1967) is an Indian slide instrumentalist, vocalist, composer, and orator, who created the concept of melharmony. He is the son of gottuvadhyam player Chitravina Narasimhan and the grandson of Narayan Iyengar, who was also a Carnaticmusician.

Ravikiran was born in Mysore, Karnataka. He made his first appearance at the age of two, in April and again in August 1969, in Bangalore, and was interviewed by Semmangudi Srinivasa Iyer, Pandit Ravi Shankar, M S Subbulakshmi and Flute T R Mahalingam. He also performed at the XLIII Madras Music Conference held at The Madras Music Academy in December 1969, and was awarded a scholarship from the academy. He was able to identify about 325 ragas (melodic scales) and 175 talas (rhythmic cycles) of Carnatic music. Ravi Shankar is said to have declared “If you don’t believe in God, look at Ravikiran”. Soon after, he was presented at leading institutions such as Shanmukhananda Fine Arts, Bombay and Tyagaraja Sabha, Coimbatore.

Following training under his father, Chitravina Narasimhan, Ravikiran debuted as a vocalist in 1972, when he was five years old, in Coimbatore.^{[citation needed]} He performed at concerts in Madras, Mysore and Bangalore until he was 10.
