A metronome on its own clock — with or without the étude.
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.) Its first button starts and stops the click (stopping it stops the étude too); tap the second in time to set the tempo, or type or slide it, 15 to 300. The time signature and subdivision are the grid the étude walks on, the accent marks each bar's first beat, and the speaker mutes the click — muted is the volume at zero.
Transport
BPM
The étude's walk — Play joins the grid at the next bar.
Plays the étude: the arrows step a chord back or forward, and the middle button plays from the first chord — or from the chord you stepped to while stopped. 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). Sound starts on your first click. What sounds — the voice and each level — lives in the Mixer card beside this one; the click's own level lives in the Metronome card — the metronome owns its sound.

What sounds — the voice, and each bus's level.
What sounds, and how loud: the first list picks the instrument sound for the voicings, and the two sliders set the chord's level and the bass's. Each slider's speaker icon mutes it — the icon is the slider at zero. A muted chord with bass and click sounding is play-along: you supply the voicings. The click's own level lives in the Metronome card — the metronome owns its sound.
Centricity
This card sets the key and its scale, and the progression that walks through them: a cycle of 4ths, 6ths, 3rds or 5ths, or up the scale, with the rule it follows written underneath. Choose the chord it starts on, and which chord tone sits lowest in the first voicing — after that, the voice-leading decides. The last list puts the root under every voicing as a pedal, heard and drawn on the score and the keys, or leaves the voicings alone.
Shape & Motion
This card shapes each voicing and how it moves. Pick the four strings and the voicing family (close, drop-2 or drop-3); a figure — a preset, or your own typed as string numbers (pattern) or roles (tones), separated by dashes — turns each chord into a line. Grip keeps one note per string anchored to the zone on the neck; Free takes the smoothest voice-leading. Strum, arpeggiate or both sets how it sounds, and the two checkboxes mark the roots on the lower strings and dim R and 5 to leave the guide tones.
Timeline
The chords in order — click a bar to jump, or step with the transport.
The progression in one row: one chip per chord, as wide as its beats, with the root's degree colour and its function. Click a chip to jump there; the current chord is outlined, and the row scrolls to keep it in view. The transport beside it plays and steps the étude from here.
On the neck
The faint dots are every note of the key; the four solid ones are this chord's voicing, coloured and labelled by degree against the chord's root, gliding to the next chord — a black ring marks a voice that moves at the next change. The window shows the whole neck, follows the frets the progression uses, or draws the zone as a box you can drag (or move with ← → once the neck is focused). The checkbox beside them holds the anchor voice in the zone; a bar that can't reach it says so under the readout. Click any dot to hear it.
The étude — end to end (click a bar to jump there)
Every chord of the étude on a grand staff at sounding pitch, each bar as wide as its beats, with the symbol and numeral above; the current chord is shaded. Strummed, or with no figure, each chord is a stack; with a figure it's written as the run you hear, approach notes small, and with the root as a pedal it sits in the bass clef. Click anywhere in a chord's column to jump there.
On the keys
This chord on a piano, C2 to C6: the four voicing notes as dots in their degree colours, each labelled, and the root below them when the pedal is on. Click any key to hear it.
