Ka is a one movement composition for chamber orchestra consisting of three sections. The work's harmonic, melodic and rhythmic materials are derived from the Chinese I Ching ("Book of Changes"). The middle section was composed with the aid of a computer program written by the composer. The program generated the interval sequence arrays forming the harmonic basis for the piece. Ka is scored for flute, oboe, B𝄬 clarinet, bassoon, French Horn, trumpet, trombone, three percussionists, violin, viola, cello and double bass. The score is 62 pages with a 39 page analysis preceding the score. Ka has a duration of approximately 10 minutes with no pauses between sections.
