Oskar Schlemmer Triadic Ballet, fragments. The idea of the ballet was based on the principle of the trinity. It has 3 acts, 3 participants (2 male, 1 female), 12 dances and 18 costumes. Each act had a different colour and mood. The first three scenes, against a lemon yellow background to affect a cheerful, burlesque mood; the two middle scenes, on a pink stage, festive and solemn and the final three scenes, on black, were intended to be mystical and fantastic.
