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.
