Æther for string quartet and amplified difference tones. This is a drone piece in Just Intonation. The instruments are processed by the computer to amplify their difference tones: pitches naturally produced which are the difference between the frequencies of any two pitches.
Performed on 10/31/12 by the Orava String Quartet on Pendulum New Music at the University of Colorado.
Video of the performance (unfortunately the audio is very quiet)

Here is short piece made for a memorial concert for my friend Christina Parks who died recently. I recorded myself playing the first 7 partials of the low B and C# and the first 6 of the low F# of the flute, all in just intonation, composed with only those pitches, and run them through some overdrive distortion to bring out the difference tones. This version was intended to be one part of a collaboration between Krista Penney, Caroline McCaskey, and I so I kept it short. Sometime soon I intend to expand this to a larger work that could be performed by a flute ensemble with live processing.
Pulses (2009) for Bonang Pelog, Electric Guitar, Pentachord, and Contrabass explores the unique timbral qualities of the gamelan and a long string instrument mixed with more “traditional” instruments. The string instruments play only natural harmonics in order to match the Just Intonation tuning of the bonang. The Pentachord is a long string instrument built by Cole Ingraham.
Third Transmutation (2008) is a djembe solo written to emphasize the rich timbral qualities of the drum. Through a progression of gradually changing rhythms, dynamics, and tones, a wash of overtones is created.
