ELOY, JEAN-CLAUDE - Gaia-Songs

"Gaia-Songs (1992, revision 2015). For a soprano (or mezzo-soprano) solo and an actress voice (Sprechgesang technique) with electro-acoustic (fixed sounds). Anne-Lisa Nathan , mezzo-soprano. Helena Rüegg , actress voice. "First there's this relation between sung voices and spoken voices with regard to the electro-acoustic parts. The sung voice is quite often separated from the electro-acoustical parts accompanying it. They may sometimes overlap each other but rather briefly. Those parts often highlight octave ratios, fifth ratios, third-ratios, etc. Hence more harmonious and consonant acoustic ratios. By contrast the spoken voice fully covers the electro-acoustic parts dedicated to it and made out of more complex material. Hence more dissonant acoustic ratios turned towards noises spectrums." JC-Eloy from the liner notes."
