曼彻斯特大学音乐专业作曲课期末作业：Compose a piece between 2' to 2 1/2 minutes using three or four instruments drawn from at least two instrumental families (which can include percussion and keyboard). The piece will be composed entirely of ONE opening motif and numerous variations, permutations, concatenations, transpositions, and other developments to which you subject the motif. It will also deploy a WIDE range of parameter changes, mostly with unexpected, surprising changes. REMEMBER: A MOTIF IS A SMALL, RHYTHMIC UNIT WITH A DISCERNIBLE CONTOUR, NOT A MELODIC THEME. You MUST circle the opening motivic unit.
