Program Notes
The Shnth is a new instrument that combines a variety of playing surfaces with a programmable sound engine. It is unusually well-suited to just intonation as it uses integer ratios to describe all pitch relationships.

Here, the Shnth is combined with realtime electronic processing implemented with the Csound programming language. The piece explores the harmonic content revealed by manipulating the spectra of long tones and chords tuned to pure intervals. The title is from the first chapter of Samuel R. Delany's novel Dhalgren.
