Today, no other artiste personifies the popularity of film music as does Ilayaraja. He entered Tamil films in the mid-1970s, when there was stagnation in film music. Ilayaraja's creations came as a whiff of fresh air. The song that made him famous in his debut film Annakili (1976)-Annakili unnai theduthu (Annam is looking for you)-was authentic folk. In his 30 years in cinema, he has composed music for more than 1,000 films in Tamil and four other languages.
But what sets apart Ilayaraja is his grasp of the role of music in cinema. Very few music directors, with the possible exception of L. Vaidyanathan and Salil Chowdhry, have demonstrated an understanding of the medium of cinema and the role of a musical score in the narrative. Ilayaraja doesn't believe in creating film music as a mere aural experience, isolated from the images. For him, music is integral to the effect of the movie. It has to integrate with the narrative, not intrude upon it. It has to go with the images, has to be part of the viewing experience.
