PARMEGIANI, BERNARD - De Natura Sonorum
"De Natura Sonorum (1975): Premiered at the Salle Wagram in Paris on June 3rd 1975. A suite of 12 movements, divided into two series of six. The first series comprises six related movements, usually organized in pairs, electronic sounds with instrumental and more rarely, concrete sounds: Incidences/resonances bring into play controlled resonances akin to sounds of concrete origin in a process that helps to expand the variable electronic sound sources. Here, incidents are opposed to one-off accidents in the second movement: Accidents/Harmoniques (Accidents/Harmonics). In the second movement, very short events of instrumental origin change the harmonic tone of the continuum they interrupt or overlap. Moreover, the high notes are underplayed, which stimulates the attention given to other phenomena generally hidden by the melodic form applied to the instrumental play. G_ɬ©ologie sonore (Sound Geology) is similar to a flight over an area where different sound layers come to the surface one
