Stir up some words
Seven-tone signature, audition tuning only. Set each tone to any note in the scale; Shift moves all seven together, keeping the intervals between them. The default climbs the rainbow — red, orange, yellow, green, blue, purple, which runs counter-clockwise round the wheel — and ends on S. With letter tones on, typing a word sounds each letter's own wedge; accepting a word strikes every letter it used at once — which is why the scale's clashes, if it has any, are heard for real.
The tail: what plays behind the confetti once the pangram has broken up. The three notes are its voice and the shape is what they do; every shape is built from the same three, so choosing between them is choosing a gesture rather than a tuning. At a gap of 0 the spread shapes land together and become a chord. The gap stretches with the animation speed, like every other onset.
Ordinary stage sound — this panel starts from what ships, and a player's build ignores every change made here. The cue is hung from the Slam's own landing beat, so it arrives with the picture rather than on Enter.
Master and Legend — the stage cue's arrival, made larger, each on its own animation's beats. Both end as the milestone's dialog opens, a second and a half after the word, so the replays here open a stand-in for it at that moment: without it the ending lands on nothing.
