In the premiere of Karlheinz Stockhausen's Sonntag aus Licht on October 16th at the Donaueschinger Musiktage Festival, Kyma was used for live ring-modulation of the trumpet and flute. Stefan Tiedje of CCMIX programmed the Kyma Sounds and set up the Capybara at Stockhausen's studio in Kürten so he could work with it during the period of May to October of this year. In the opera, musical shapes are played in and out of phase with each other at increasing and decreasing time intervals: first for the Bassett horn with flute and then for tenor with trumpet. Both pairs meet occasionally at time zero. These temporal phase shifts are repeated at the microsound level through the use of ring modulation. For Stockhausen, the sum and difference tones of double ring modulation are like the reflections of a "magic mirror" generating new harmonies and tonal qualities.
