This brief work was inspired by a Spitzer telescope image of the nebula m45 and is a piece of visual music in which the processes for synthesizing the sound and the video footage are closely linked. An algorithm for generating cellular automata has shaped the dynamic harmonic structure of the long bass tones and the rhythms of the “celestial handbells” that hover over them. The pitch relationships among the drones are governed by a technique of adaptive just intonation, and the pitch relationships among the bells are based on a scale formed of four tones that are equal-tempered divisions of a pure major sixth. The visual imagery was synthesized by mapping the sound synthesis control contours to various attributes of a Jitter patch.
