in other words... they construct their pieces
after analyzing particular spectra from concrete sounds or
acoustic instruments....and then they
apply them into their orchestration.
-Well actually, they transcribe the frequencies
appearing in their analysis (through the Fourier Series)
to notes available on the instruments in the classical
orchestra. Resulting in microtonal pitched music.
it is timbre-based music
-I think that this not correct:
timbre contains more elements than Fourier Analysis
shows, there is the general amplitude curvature, but
also the grouping of overtones, the amount of noise
and quit important: the attack and decay.
