Integral/parent work: Seven Spheres

The second movement is based on just one motive that contains all twelve pitch classes, each states once. In a complex counterpoint of independent tempi and at various transposition levels, the opening region of the movement presents the motive in sixteen different voices, each at a different speed; eight relatively slow, and eight relatively fast […]. The movement ends with the sixteen voices converging to eight, and with all the sixteen speeds converging to one: the rhythmic unison.
