Mattias Petersson debuts on the Swiss label Hallow Ground with »Triangular Progressions,« a suite in nine parts written entirely in the SuperCollider environment using additive synthesis. The starting point for the evocative piece is a magic number triangle that Petersson invented during his early composition studies and which has been an obsession of the artist for over twenty years, previously forming the foundation of many other of his works. By exploring the harmonic progressions found hiding within the triangle, »Triangular Progressions« at once emits a sense of introspective calm that fosters deep listening and evokes a whole spectrum of emotions, mediating between the abstract and the visceral.

The Stockholm-based Petersson, also known under the moniker Codespira1 and for his long-term collaboration with violinist George Kentros as There Are No More Four Seasons, has been active as a composer of computer music as well as an artist in the realms of live coding and modular synthesis for over two decades. Originally trained as a classical pianist, he also holds a diploma in electro-acoustic composition from the Royal College of Music in Stockholm, where he currently works as an associate professor. Besides his activities as a musician and teacher, Petersson is pursuing a PhD in composition at the Luleå University of Technology. Researching modular systems comprising both human and non-human modules, he is part of the GEMM))) Gesture Embodiment and Machines in Music cluster.

»Triangular Progressions« can be considered a perfect synthesis of Petersson’s academic interests and aesthetic ideas, combining a mathematical approach with artistic rigour. The magic number triangle highlights the beauty of symmetrical properties. By exploring its idiosyncrasies, the composer manages to translate them into engaging sounds. The lush melodies and harmonies of the music at times call to mind the intimate organ and drone works by label mates Kali Malone and Maria W Horn while also maintaining a unique signature sound. The addition of pure sinusoidal waves enables a deep listening exploration of the counterpoint between melodic and harmonic rhythms, chord structures and spectral harmonies that Petersson extrapolates from those magic numbers.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I've become addicted to drone. Again. I was the kid with his head on the piano, listening to the overtones die away, or pressing his ear to the steel hull of the ferry, enthralled by the sounds it created. I was the kid who formed wordless songs to accompany the sound of train wheels on a long journey, or hummed along with the fan on a hot day.

In the 60s I used to play my 45s on 16, or backwards, or by hand using razor blades as stylii.

I made cut-up tapes on a cheap cassette recorder in the 70s and experimented with reel-to-reel in the 80s. 

Thank you Subotnick, Lygeti, Coltrane, Jimi, Mimaroglu, Eno, Cluster, Tangerine Dream, Klaus Schulze, Frank Zappa, Pink Floyd, Kraftwerk, Throbbing Gristle...

I am not a musician. I am a scavenger of sounds. I use the most basic software to process those sounds, stretching and filtering until something emerges that makes a joyful noise. Or not...
