Born in Hamburg, Germany in 1953, Wolfgang von Schweinitz is a composer based in Flensburg, Germany. With Marc Sabat, 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. Since 1997, von Schweinitz’ compositions have been concerned with researching and establishing new microtonal tuning and ensemble playing techniques based on non-tempered just intonation.
