Duo Sonata is in four movements each exploiting a different musical style characteristic while sharing common motives and themes:
1. Departure is a highly chromatic and rhythmically driven movement in sonata form. Opening with a fast unison passage (introducing the two instruments as if they together were one), they separate - dancing in homorhythmic passages - only to return to the opening phrases in octaves.
2. Elegy is strictly white-note aeolian and freely rhythmic. Perhaps more importantly, it was composed very quickly as a reaction to the tragedy of September 11, 2001. It has since been rescored for sting orchestra, string quartet, wind ensemble and saxophone quartet.
3. Like Departure, the Scherzo opens with the clarinet and saxophone in unison silences only to find themselves simultaneously presenting simple motivic ideas in a 2 vs. 3 polymeter.
4. Unlike the previous movements, the groove presented in Arrival (Blues) requires the performers to consider those points "when not to play," as Al Woy humorously put it. It is a fast blues (proportional to the 12-bar format) with a contrapuntal development. - the composer
