Halflight

A projector’s line drawing becomes planes of light in haze. The drawing follows the song: height maps to pitch, left and right to stereo position, brightness to level, and blur to the filter. A♯ is the only gold pitch class. When F♯ minor turns to F♯ major at 42 seconds, the image turns gold with it.

The original 60-second song was composed and sound-designed as code, mixed through a Python pipeline and assembled in Logic Pro. The film reads the score, composer’s curves and stems to build its visual score. The delivered film is v2.0, and the separate audio player plays the original track.
