Recording of Marco Pedrazzi's Aqua Mater. Composed in Milan in 1998. The composer speaks of water as the symbol (and maybe not the only symbol) of the matrix and of the dynamic of life; the water of the existences. The water is the place where there is birth and death, and it is the place of the beginning where all possibilities have to be realized and all the thigs must go back. In ancient cultures, the sea on our planet and the celestial sea set upon us were always described as deriving from the same nature. The water can be understood as the place of the creation of all souls, with all beings (men, gods, animals etc.) descending from it. To pass the sea means a spiritual initiation, a passage from one being's condition to another one. This work is an homage to this. The work has been composed over a year using huge complex dynamic sounds events, paraharmonic synthesis, and vocal research. The sound events have been generated using complex partials, harmonic shifted and formants synthesis. The parts of this work have been written and synthesized with CSound, edited and processed with Soundhack and Digidesign software. Languages: CSound.
