Ellen Arkbro (1990, Stockholm) is a composer and sound-artist primarily working with intervallic harmony in just intonation. Her work includes long duration compositions for ensembles as well as electronic sound environments in the form of installations and live-performances, employing both traditional acoustic instruments as well as digital algorithmic sound synthesis. Most recently, Arkbro released for organ and brass on Subtext Recordings, a set of recordings of her compositions in just intonation for renaissance organ, horn, trombone and microtonal tuba. In all of her work, Arkbro focuses on the qualities of harmonic sound that reveal listening to be an active process of participatory construction rather than mere observation, inviting the listener to gradually transform into the sound itself.
