. . . The Book of Music for 2
Pianos . . . employs
the rhythmic structure I have described earlier. In this case, however,
the number of sections is 31 and each section has 31 measures except when
the tempo changes. The number of measures then changes accordingly, thus
showing that actual time-length is the basis of this plan rather than arbitrary
numerical relationships. . . .
