Born in Kitchener, Canada in 1965, Marc Sabat is a composer and violinist based in Berlin. With Wolfgang von Schweinitz, he co-founded the Plainsound Music Edition website in 2000, conceived as a curated, interdisciplinary virtual artists’ edition. The site features open source, non-commercial sharing of experimental, perception-driven artistic work and research, with a major, but not exclusive focus on the practice of microtonally extended just intonation. In collaboration with Catherine Lamb and Rebecca Lane Sabat co-founded the Harmonic Space Orchestra in 2019.
