Second Sundays #3 – Marc Sabat
This session focusses on Berlin composer Marc Sabat’s pieces using “tuneable intervals”, a harmonic system he has built up and crafted over a rich body of work. He writes: « In John Cage and the Theory of Harmony composer James Tenney described an idea of « harmonic space » — a network of connections between tones, based on frequency interactions which our auditory cognition system automatically recognises. His idea is a development of the tonality diamonds described by Harry Partch and lattices in Ben Johnston’s « extended » just intonation. I call these special, perceptible frequency relationships « tuneable intervals ». Their combinations in various acoustic and electronic constellations form the harmonic basis of my music. »
