This is an algorithmic composition for sounds of saxophone. Its goal was to use normal functions for achieving musical expression, melodic sketches and rhythmic counterpoint. There is a sound-space, and repetitions which go out of phase, thereby unfolding the structure of this piece. ExpySax(n) is a tribute to music educator and performer Terry Mohn. This piece was composed using the SCHEME programming language on Bill Shottstaedt's Snd.
