Orchestral Work.

Someone on my forum yesterday, commented rather harshly on a work of mine stating that it was rhythmically inflexible. So in response to him, I am working on an orchestral work with the goal of presenting one chord that slowly evolves and changes every 8 bars to eventually come back at the very end. To accentuate and provide interest to the piece: I use alteration in rhythm within the percussion (triangle, timpani, glockenspiel, and slapstick). The rhythm of the sustained chord I also alter slowly every 8 bars presenting new rhythms AND accentuating the chord with a motif that changes as it goes from instrument to instrument (first winds, then violins and clarinet, then horns/viola/violoncello... etc.) So far its a very interesting piece.
