His health deteriorated during this time and died in 2002 with the Kannada film Vishwamithra (2001) being his last work. Kumar won the Karnataka State Film Award for Best Music Director three times (for Nanjundi Kalyana, Hrudaya Haadithu and Jeevana Chaitra) before stopped composing for films in the mid- to late-1990s. "Idu Yaaru Bareda Katheyo" from Premada Kanike was based on this raga. The mandolin and the sitar were prominently used in Kumar's instrumentation, and he was particularly fond of Kafi raga with melodies deriving from that scale. Lyrics for most tracks of the Upendra Kumar–Rajkumar combination were written by Chi.
