The film is a live orchestral score on ivory paper. Each staff is a metric, the notes are its values, and a baton-shaped playhead sweeps in time with the soundtrack, trailing swooping ligatures. One note goes sour; Pulse circles it in coral and the human gives the cue that brings it back into tune.

1 · HOOK0:00–0:08
The camera scrolls right across an overcrowded 38-part score; notes pop on every 8th but nobody is conducting. On the downbeat before the drop one grey note below the Checkout staff gets a dashed ring and "heard: Fri 17:40" types in.
2 · REVEAL0:08 (drop)
The baton's ligature swoops left to right across the page (path draw, power2.out 0.6 s) and lands on the coral dot exactly on the drop. The title page sets: the mark, "Acme Pulse", then the italic credit on the next beat.
3 · PROOF MOMENT0:12–0:32
The baton playhead sweeps left to right one bar per 2 s; every note pops 1→1.15→1 exactly as it passes. At bar 12 the Checkout note wobbles and sinks below the staff, the coral ring draws on, and on the human's cue ("Roll back") it slides back up to the dashed teal pitch with elastic.out.
4 · CTA0:36–0:45
The score scrolls to its last bar; a teal final chord stacks bottom to top, one note per beat. "Every metric." on beat 1, "Every minute." on beat 3, and the double barline and "fine." land on the last downbeat with the button.
COMPONENT KIT
Staves — one five-line staff per metric, labelled in italic serif.
Number-notes — note heads on stems with the metric value set as the lyric.
Baton playhead — teal vertical line with a trailing swooping ligature.
Dissonance ring — coral circle and ledger lines around the note that fell out of range.
Ghost pitch — dashed teal note head showing where the value should be.
Conductor's cue + final barline — the human decision, then "fine." as the CTA.
MOTION · MUSIC
On-beat pops — each note scales 1→1.15→1 (0.12 s up, 0.2 s down) exactly when the playhead crosses it; one bar = 2 s at 120 BPM.
Baton ligature — the swoop path draws along the baton's trail and fades, power2.out 0.6 s, always landing on a downbeat.
Retune — the sour note wobbles ±4° for two 8ths, then slides to the ghost pitch with elastic.out(1, 0.5) in 0.6 s on the cue.
WHY / RISK · ADAPT IT
A music-driven film about a score is self-reinforcing: every cut is literally on the beat, and "one note out of tune" is an instantly legible anomaly. Risk: with sound off the sour-note gag must read visually, so the note must fall well below the staff, wobble and turn coral.
Adapt to your product: Give each of your signals its own staff (queues, regions, customers, costs) and let the playhead be your product's run or sync cycle.
