The expansion into the lower register is also emphasized at the end of Event One
when the original material centered between 134-586 Hz drops out. Material at around 80
Hz. quietly enters at around 3.8", growing in intensity until a prominent impulse at around
76 Hz is heard just before 8". This coincides with the exit of the centered material. The
first event is then punctuated with another low impulse at 63 Hz, along with a faint
reinstatement of the centered material at around 10". Taken together these low impulses
at the end of Event One, along with the higher material at and above 1034 Hz, emphasize
the low and high registers and thus the expansion of register from the original centered
material.
The second event expands this motion even further, suggesting upwards motion
within its own span and also continuing to push upwards into an even higher register than
the first. At its peak Event 2 reaches 6676 Hz, and also extends as low as 40 Hz. Like
Event One, this event ends with low impulses; these occur in two pairs, the first, being on
the diffuse end of the spectrum, and the second more compact and at the same pitch
levels–76 and 63 Hz. It is, in fact, because of the precedent set by the low impulses
ending Event One that I hear these compact impulses (which are separated by brief rests
on either side) as the end of Event 2 rather than the beginning of Event 3. The short, third
event plateaus in this register, filling out the entire spectrum more densely and rapidly than
the other two, punctuating the passage as a whole.
Dynamics and Attack Strength
The levels of intensity (dynamics) and attack characteristics also suggest a
consistent trend, accelerating and growing louder across the events of Region A. First of
