Metronome
BPM72
Vol80
A full metronome on its own clock — use it with or without the étude.
The étude subscribes to this grid. (Shared component: every At-Etudes app carries this
metronome, first block, this look.)

BPM72
Chords take the bar's slots in order — e.g. 5/4 split 2+3: first chord
2 beats, next chord 3, new bar. If the metronome is running, Play joins it at the next
bar — the click you already hear is your count-in. If it isn't, Play starts it
(count-in adds one clicked bar first). Stopping the étude leaves a self-started metronome
running; the metronome's Stop stops everything — it owns the clock. What sounds — the voice
and each bus's level — lives in the Mixer card beside this one; the click's own level lives in
the Metronome card — the metronome owns its sound.

Each slider's speaker icon mutes that voice — the icon is the slider at zero,
and a muted chord with bass and click sounding is play-along: you supply the chords.
Centricity
Triads first, meaning added underneath: with a bass, every dot is
relabeled relative to the new root — the same shape changes meaning.
Type the progression you actually face, or grow it chip by chip
with +. The app derives the upper-structure triad on your string set and grounds
it on the chord's root in the bass. Tap a chip to edit it — where a chord holds
more than one honest triad the chip grows a ▾. Romans resolve in the selected
key.
Shape & Motion
? pivots, placement, and the badges
Pivots: click any scale note on a string of the set — that note and the next two scale
notes up the same string become your pivots (dashed rings). Placement decides where the
figure's notes live: Grip — one note per string, playable as a chord, anchored to
your pivots; Line — notes placed freely
along the set, up to three per string, preferring the pivot window, playable in
sequence rather than as a chord; Free — the
grip chosen by smoothest voice-leading, anchor released. The dashed box simply draws
where the figure ended up living — a consequence of the placement, not a setting.
Changing set, key or scale carries your pattern and pivots along — same figure, same
degrees, new context. Order badges on the sounding notes show each string's position(s)
in the pattern.

Note — what just happened
that note is filed nowhere —
Save entry files the note with this étude's full configuration
and clears the pad — the emptied pad is the confirmation, and the entry appears in
the log beside it; Restore on any row rebuilds that exercise exactly. Saving with
an empty pad is fine — it captures the étude alone. Export writes one .atchart.md:
anything still in the pad rides on top as uncommitted scratch, the entries below it
are committed. Import merges — nothing deleted, duplicates skipped; old exported
logs and bare étude configs (.json) still open.
