Detailed Analysis of Regions
Region A
Region A, (0"-18") shown below in Figure 3.6, exists entirely in the right channel
and is divided into three events based on rests and changes in sonic materials, although the
region is largely consistent in its use of impulses–occupying an intermediate state between
pitch and noise. The first event is the longest, slowly fading in and ending at 11"; there is
slightly over a second’s rest before the entrance of Event 2. This event has the widest
range of Region A stretching from approximately 40-6676 Hz. A smaller pause (17.3"-
17.5") separates the third event which is also distinguished by being the loudest and having
the most prominent attacks. These events create a strong impression of expansion and
acceleration through their coordinated use of patterns in register, and in dynamics and
attack strength. See Figure 3.6, a spectrograph of Region A.
Register
In terms of register, Region A begins with most of its activity centered between
134 and 586 Hz, however, within the course of the first event, the register quickly
expands in both directions. The rise in register is made apparent by the rate at which the
material above 600 Hz. enters in the first event. The material above 600 Hz begins
quietly, but steadily gains in intensity in pushing upwards through areas of approximately
1200, 1600, and to a peak of 2287 Hz just before 8". A strong element at 1034 Hz
th
continues in the 9 second while the centered material between 134 and 586 is silent,
clearly emphasizing the higher register.
