What Harp shows
Harp raises a laser harp around the album art: twelve single-colour beams rise from an emitter on the floor and fade into the dark, above low smoke and a floor that reflects them. Each beam is a note, from the lows on the left to the highs on the right.
The music plucks the strings: a beam is cut at a height, lower for a loud note, the cut point flares into a star and a few sparks fall, then the beam grows back. The lows play on the left, the highs on the right; a build-up becomes a glissando, and on the drop every string is cut at once before the fan opens wide.
