CNP's first assignment as a music composer was the 1948 Sinhalese movie Kapati Arakshakaya directed by K. Subramaniam.
The movie was a runaway hit and CNP's compositions sung by the famous Eddie Jayamane and Rukmani Devi became very popular.
This led to CNP composing the songs for a few more Sinhalese movies in later years such as Veradunu Kurumanama, Amma, Sihinaya and Devasundari.
[1] Composer Vedha worked as his associate for some years and learned the nuances of music composition before branching off on his own.
He used to encourage the lyricists to come out with appropriate, poetic lines and would not hesitate to amend the tune to accentuate the beauty of the lyrics.
[1] He worked with singers like T. M. Soundararajan, A. M. Rajah, Seerkazhi Govindarajan, Thiruchi Loganathan, C. S. Jayaraman, V. N. Sundharam, P. B. Sreenivas, S. C. Krishnan, T. A. Mothi, K. R Chellamuthu, A. L. Raghavan, M. Balamuralikrishna, S. V. Ponnusamy, K. M. Mani Rajan, M. L. Vasanthakumari, P. A. Periyanayaki, P. Leela, Jikki, T. V. Rathnam, A. P. Komala, K. Jamuna Rani, P. Suseela, Radha Jayalakshmi, A. G. Rathnamala, Soolamangalam Jeyalakshmi, Soolamangalam Rajalakshmi, K. V. Janaki, K. Rani, G. Kasthoori, S. Janaki, and L. R. Eswari.
The singing actors T. R. Mahalingam, K. R. Ramasamy, S. Varalakshmi, V. Nagayya, B. Jayamma, N. S. Krishnan, T. A. Madhuram, P. S. Govindhan, C. S. Pandiyan and J. P. Chandrababu also sang memorable songs under his compositions.
Even though many of the movies were commercial failures, yet CNP shows his erudite classical roots, technical finesse, inventive arrangements, uncanny grasp of the mood and sequence and astute pick of a variety of singers.
