While most etudes are designed to feature the instrumentalist's virtuosity, my "Three Etudes in Sound" are mainly concerned with color and sound control. The first etude, "Sound Layers", is comprised of several strands which need clear delineation within a dense texture. The second, "Sound Swirls and Spikes", challenges the pianist's ability to imagine and to negotiate various "shapes" of sound. In the final etude, "Sound Sustained", several competing ideas must be "mixed" and paced so as to maintain a continuous line. The piece was premiered in 1993 by myself at the Austrian Embassy in Washington, DC., and later received its New York premiere by pianist Soheil Nasseri.
