Monophonie by Phillip Sollmann

Following 2019’s ‘New Atlantis’ LP under his experimental techno alias Efdemin, Phillip Sollmann’s ‘Monophonie’ is a project dedicated to uniting different strands of utopian music. His approach: combining and recontextualizing rare historical instruments of sonic research of Hermann von Helmholtz (19th century) with the self-designed, microtonal instruments of Harry Partch and metal sound sculptures of Harry Bertoia.

The result is a psychedelic investigation into just intonation – alternative tuning systems that create unique sets of harmonics not found in conventional scales. ‘Monophonie’ recasts these sounds into new rhythmic environments where epic kosmische, polyrhythms, acoustic techno and microtonal glow are interwoven into a rare music.

Over nine tracks, the album explores multiple forms of minimalism, from unwavering repetition to paired-down chords and sparse sonic environments. But it also seeks to expand the sound spectrum of Partch’s custom built organs and melodic percussion instruments as well as Bertoia’s sonambient singing metal rods into an atmospheric otherworldliness.

‘Monophonie’ was first composed in 2016 and premiered at Berlin’s Volksbühne theatre in 2017, before it went on to the renowned Ruhrtriennale and Kampnagel in Hamburg. It was performed by one of Germany’s premier neue musik collectives Ensemble Musikfabrik together with Sollmann himself on von Helmholtz’s original double siren, with set design by Michael Kleine and wardrobe by Peter Kisur of Honeysuckle Company.
