R
The first pair of anomalies, which coincides with the denser part of Section F , fits into the
arch shape quite readily, but the second pair begins to stand out more prominently, and
R R
thus helps prepare the following sections. Sections E and D occur in the place allotted
R
by the schematic form and outside the arch shape of Sections F and F , but prepared as
they are by the anomalies in descending registers, these sections can also be seen as
R
extending this descent past Section F , and smoothing out the transitional area between
the two stages of the second half of the piece.
R R
The reprise of Section B overlaps with the end of Section F and beginning of E ,
but Section B is largely filtered and stands out from these sections in only a few places.
The first pizzicato glissando of Section B is filtered out, and the second instance (20 Hz
R
noise) occurs at 4'35" just before material from both Section F and the second instance of
Section D material. As such the beginning of Section B is not as well marked and does
not readily define a division of this stage of the piece. Material from B is nonetheless
notable at 4'51" in the highest register, and again from 4'58-5'07", although in both of
R R
these instances it occurs along with material from Sections F and E .
Retrograde of Section E
The retrograde of Section E is more intact than the reprise of either Section B or
C, with which it overlaps. Furthermore, the second anomalous area prepares Section E by
R
using transpositions of its material. Section E as shown in the spectrograph below, is
intact except for the second event–the very event which is used in the previous anomalies.
