A stunning example of spectral music
From Tristanmurail.com
This piece constitutes perhaps the most thorough and exhaustive work Murail has done to date on the examination of purely instrumental spectra. All the computer-generated spectra are directly modelled on real instrumental sounds. The computer does not however, attempt any direct simulation of the instruments concerned. Rather, it is a question of using certain spectra as structural analogies for the entire pitch content of the work (whether on instruments or tape) and likewise to generate its large-scale forms. This ensures that the computer sounds and those on tape have a common unity which ensures that they maintain an audible organic unity the one with the other - indeed, the extent to witch taped and instrumental sounds fuse and blend throughout the work is unusually consistent, not least given the technology of the time.
The title refers to the technical processes involved - to the desintegration of a timbre into its individual components - sounds melt before us, revealing their interiors before our ears. But it could equally be an allusion (perhaps unconscious) to the constant flux of the music between moments of order and consonance to moments of disorder and noise as the primarily harmonic spectra are disintegrated and deformed into irregular and inharmonic ones.
