ww9 represents a departure from sound-oriented
material in that the first step was to produce a set of images formed
by hand-cut patches of black paper set on fields of white. Next the
visual media was sonified by implementing an FFT filter over white
noise, in effect: subtractive synthesis.
This pre-ordinance of the visual over the aural has the result of creating recognisable patterns for the eyes which are quite alien and unnatural for the ears. If the exercise were to be reversed: a piece for piano translated to a spectrogram, the untrained viewer could have difficulty perceiving the organisational systems in place.
All images are read from left to right with the exception of 9.07 and 9.05 which are read from top to bottom and bottom to top respectively.
