Increment (2010) for clarinet and percussion, commissioned by Caleb Herron, is a work with a simple incrementing structural scheme that focuses on interaction between the two performers. The work was composed with the use of weighted interval sets, markov chains, and the various gesture driven algorithms. The Common Music/GRACE algorithmic composition environment was utilized as well as several primitives programmed Max and Java.

Calliphora is a beautifully misleading word which refers, not to an idyllic fantasy island set on crystal blue waters, but the genus of the common Blowfly. Using the numerology of the Flies life cycle and computer generated sounds which aim to mimic the sonifications of these insectoid organisms, Calliphora is a segmented work of alien sounds in a familiar environment. As if under the microscope, studied from various angles, this work attempts to find beauty and interest in a subject most find abhorrent. Calliphora was written for another striking and misunderstood phenomenon, the bass recorder. Flies are still gross, though.

Engineered to provide dual meanings, Subconscious Train Matter is a look into the effects of aleatoric call and response, and an intentional effort to create something organized that actually requires a little work to play (hence training and mattering). In addition to simulating a train sound with the neutral third, I also create thick textures with much auditory mass, or matter. The pitch content feels like a common auditory illusion – one is listening to some consistent pitch material, and then there is a slight unexpected bend, due to a cold or other physiological reasons. This is accomplished by changing the relationship of large step size to small step size in the continuum, so that the scale approaches either 10-equal (L=s), or 7-equal with three ‘doubled notes’ (s=0). After the first four minutes explore the effects of similar passages played with gradual shifts, the final improvisatory section uses the changing continuum as a more immediate expressive device. Hopefully this piece scratches the surface of some of the exciting xenharmonic opportunities that are possible through dynamic tonality.

Thanks to the performers!

Sk’elep is an alternate name for Coyote in the Secwepemc or Shuswap language group, a tribal language spoken in the Canadian province of British Columbia. In Native American mythology, a coyote is a trickster god and is generally benevolent. The coyote is highly respected for its cleverness and its will to survive.

This work follows a sonic journey through a collection of landscapes. The first is a cityscape to acknowledge the presence of coyote in our modern cities. The work then transforms to a rural environment reflecting the coyote’s original habitat. From there, the piece evolves into a mystical setting reflecting on the spiritual connection that the coyote symbolizes in Native American Culture.

Realized in the University of Illinois Experimental Music Studios.

End of Message was realized at the University of Illinois Experimental Music Studio during the 2008-09 school year. The title marks an end of an era, a time the composer does not wish to revisit. To write of it here would be missing the point entirely.
