the majority of his work is triadic and contains simple, repeated progressions, or in some cases pandiatonicism. often extended tertian harmonies are followed by whole tone harmonies (such as in the first movement of symphony no. 5; or the first movement of his "cyber bird" concerto for alto saxophone, which, in addition, makes use of free atonal jazz; or the final movement of his "orion machine" concerto; or in his saxophone concerto "albireo mode"). his works for japanese traditional instruments (such as "subaru", and "within dreams, without dreams") make use of traditional japanese scales and tunings.
