IRIDESCENCE for flute, clarinet, and piano by Randall Snyder musically depicts the phenomenon of certain surfaces that appear to change color as the angle of view or the angle of illumination changes. The work begins with a six-note arpeggiated chord, each note serving as the bass of a transposed reiteration. This harmony, plus the heterophonic interplay of the instruments, creates the effect of hearing the same intervals in different perspectives. A faster section based on a linear seven-note pattern follows. The trio closes with a reprise of various versions of the opening sonority.
