THE ELECTRONIC WORKS OF GYÖRGY LIGETI AND THEIR ...

Based on the precedent of Regions D and E, we might expect a region which, after
an initial event or two, is abruptly transformed into something new, but Region F is novel
in that it changes back and forth multiple times between two types of material, and that
these types of material are, in themselves, relatively consistent–showing only slight
changes in register and rhythm, but never compromising the extremes of the
compact/diffuse dimension. This also aids the division of these materials into concurrent
streams as the two types overlap more extensively towards the end of the region. While
the discrete pitches in this region show a downward trend (Events 1 and 3 being mostly in
the middle to high register, and those of the last two events being middle to low) the
noises settle in the upper register.
Global Trend of Region F
Region F shows an acceleration in attack density, and in the speed at which the
sides of the dialogue alternate, and thus continues the trend toward greater density present
in previous regions. The first pitch based event lasts from 53.6" to 57.0", followed by a
noise event from 57.7" to 59.6". The next two events take about the same duration
(Event 3, 59.6"-1'02.7", Event 4, 1'03.1"-1'05.4") but each changes from pitch to noise,
and back within its span. Event 5 (1'05.5-1'10.0") after beginning with a high noise
element, contains both noise and pitched elements throughout its span alternating attacks
very quickly. This, combined with the cognitive perception of two materials coexisting
with different registral trends, creates a substantially more complex texture, and one which
is an important precedent to what happens through the rest of the piece.
