“Triadisches Ballett (Triadic Ballet) is a ballet developed by Oskar Schlemmer. It premiered in Stuttgart, on 30-31 September 1922, with music composed by Paul Hindemith, after formative performances dating back to 1916. The ballet became the most widely performed avant-garde artistic dance and while Schlemmer was at the Bauhaus from 1921 to 1929, the ballet toured, helping to spread the ethos of the Bauhaus.”
Under the title Das triadische Ballett, the work was produced as a 30-minute color film in 1970 by Bavaria Atelier GmbH, with live-action dancers and new music by Erich Ferstl. (source)
