activity. The introduction of differing sonic types in the same region leads to more
complex forms than the simple accelerating patterns of Regions A and B. The subsequent
regions begin to develop two-part structures, first based on parallelisms, and then having
more dramatic differences between the first and second halves. Again, this process
culminates in Region F which develops a polyphony of simultaneous, rather than
successive parts. The use of channels in creating the sense of overlapping regions is also
extremely important to the progress of Phase 2; these regions are noted in Figure 3.8.
Region C
Region C (29.8"-39.6") differs from the previous regions in that it uses a mix of
compact and diffuse sounds, rather than moderate impulses, or either of these sonic poles
exclusively. Furthermore, this region begins to vary and elaborate the types of motion
established by the opening phase; these contrasts are what set it apart as the first Region
of Phase 2. I will divide Region C into 3 events; the first is introductory, and the second
and third create specific patterns within each pair. The first event lasts from 29.8" to
31.7", at which point the beginning of Event 2 marks a move from noise to pitch, and lasts
until approximately 34.6", although reverberation carries through a bit later. I will also
subdivide Event 2, into 2a and 2b, the latter marked by a prominent attack at 33.6". Event
3 is also subdivided with 3a beginning at 35.7" and Event 3b at 38.2. This division will
help illustrate more specific ways in which Region C contrasts with A and B, as well as
relationships between Region C’s events.
