Example 37. Whirled Series’s superarray (three arrays) for mm. 157–98, with highly permeating pitches indicated with noteheads (darker corresponding to more permeation). These five partition spans demonstrate a flux from very little pitch permeation (mm. 157–59), to greater pitch permeation (mm. 160–77), to much less, almost none (mm. 178–92), to a slight pitch permeation of only one pitch: high B (mm. 193–98).
