Director Sashi Kumar wanted the music of Kaya Tharan as a parallel track in the film. He did not want the audience to be fully involved in the music, like in most emotionally charged films. He would rather have something called amelody, a melody that cannot be hummed or tuned.

As I had been experimenting with atonal music, which is a system developed in western classical music in the beginning of the twentieth century, I decided to use that in Kaya Tharan. I had also been experimenting with arrhythmic music, which is different instruments playing different rhythms. If there is only one instrument, then, I constantly change the rhythm.
