In the words of the composer: "In this little study, do not count - - let the ear determine how to achieve the echo effect." While technically possibly the easiest of the entire set, "Echoes" is musically a fascinating composition. Student will absolutely need to listen carefully, and use their imagination to successfully perform this piece. It is a wonderful first atonal piece for a young pianist, as it necessitates a heavy dose of performer input.
