Alluding to the first book of the Old Testament, the brass quintet work Genesis refers to the beginning and becoming of sonorities and intervals. Several extended techniques are employed to highlight the timbral qualities of the brass instruments in both the energetic and enigmatic episodes.

Following some gradual unfolding, Genesis ruptures into a “brassy” cliched fanfare, which subsequently simmers down into a slow-moving segment of music. It is then further developed before transitioning back to the pompous fanfare with all the presented patterns incorporated, and descents into utter chaos. Audience members may observe the intervallic changes across the entire piece; as well as the contrasts between, and the integration of order and disorder in various metrics.
