A third-place winner in the 1998 PAS composition contest for small percussion ensemble. An intense exploration of the monotonal relationship between the diminished (modulatory) and augmented (resolutory) symmetrical polytonal pitch sets. This keyboard percussion quartet for 2 vibraphones and 2 marimbas can also be performed by 3 vibraphones and 1 marimba if the players have access to a third vibraphone. The complexity of each of the individual parts mesh together to create an intriguing tapestry of ever-evolving sound.
