ItemElegy(2013) Pfaff, WilliamElegy is a brief composition without overt repetition in its large-scale formal design. The piece is unified instead by the developing variation of a single motive. The variations manifest themselves in two ways. First, the motive undergoes constant intervallic variation (what is heard at the outset as a perfect eleventh appears later as a major ninth, etc.). Second, concurrent with the intervallic alterations, the motive functions in different contexts within individual phrases: the motive may begin or end a phrase, or occur abruptly in the middle of a phrase. The combination of these two processes generates a sense of musical evolution and growth within defined boundaries.
