Example 2. Measures 1–12 of It Takes Twelve to Tango, with the subdivision series and semiblocks indicated above the staff and the aggregate boundaries indicated with vertical lines

Note that the first beat’s series proceeds to series member 2 only at measure 11 while the second beat’s series proceeds through series members 2–8 in measures 1–10 before beginning again at measure 11. Further note the coordination of two-measure aggregates and repeated subdivisions.
