This work is based on the concept that sounds are likened to colors and mixed to create a unified sound mass. While interweaving consonant and dissonant sounds within a limited motif, it exhibits both a swell of sound and musical coherence. It incorporates a puzzle element (thrill) from players' interaction leading to the vertical and horizontal musical flow.

This piece was commissioned by Niigata Wind Orchestra's clarinet quartet and premiered by the group.
