Reinhold Friedl’s Eight Equidistant pure wave oscillators, while slipping very slowly to a unison, textually spatialised on eight speakers, concret, 60 minutes is an algorhithmic composition that speaks to his unique compositional vision.
A deeply affecting psycho-acoustic work, ‘Eight Equidistant pure wave oscillators...’ draws the listener into a gently lilting sound world in which pure tones work for and against one another, creating a swelling cascade of intonation. At its core is a carefully crafted and astutely executed exploration into the possibilities of spatial sound. The guided movement of the signals across the speaker arrays, generating a very specific set of acoustic outcomes.
Like much of Friedl’s work ‘Eight Equidistant pure wave oscillators...’ taps into his interests and research into the connections between mathematics and music. The tension and release of the glissandi tones is a representation of this.
This is a provocative work that not only prioritises the act of listening, it also invites the listener to consider their position to the work and how psycho-acoustics can shape the listening experience. ‘Eight Equidistant pure wave oscillators...’ is an utterly sonic experience crafted by one of the great contemporary European composers.
