CADENCE — A SESSION FOR SMOOTH CHORD CHANGES

Learn → Courses → Make chord changes sound smooth → Begin session.
If you have not created the pathway yet, use “Use my books to begin” and select
your Rooksby EPUB and Levine PDF. The adaptive exercises are original Cadence
material and work without a model request. They do not approve imported book
notation or claim to reproduce a printed exercise.

THE SESSION

Opening check: find nearby voicings through C–F–G–C. On later sessions, a due
exact voicing task can replace the first change. Prior keyboard and on-screen
results retain separate schedules. A returning transfer task retains its own
identity when brought into the opening review.

Focused practice: after three checks, Cadence suggests a transition from the
observed chord-tone or movement difficulty. You can choose C→F, F→G or G→C.
Try it from two starting inversions; retries and this focused stage are support,
not independent recall. Every stage allows skips and continuing after a miss.

Independent attempt: D–A–G–D changes the key and the order. Hints begin closed;
opening the solution or the book marks the attempt as supported. The first
unhinted answer is distinguishable from later retries. Repeating this session
uses the same transfer progression; success is not proof of general mastery.

Composition finish: open your pathway composition, add music, choose a rhythm
and revise a change. The editor offers “Back to session”. Listen to the phrase,
describe one choice and keep it. The saved reflection links to that score
revision. You can also finish today and return to writing later.

PLAYING AND FEEDBACK

Use three different notes within one octave, between C3 and C6. Keep any shared
pitch in the same octave. Compare voices from low to high; each may move up to
five semitones in this exercise. Any inversion satisfying these conditions is
accepted. These are practice constraints, not universal rules of composition,
fingering judgments or a measure of how comfortable your hand feels.

With MIDI: choose Listen to keyboard, release any previously held notes, then
play and release the starting shape shown in the score. Cadence checks that
shape before accepting the next chord. Play and release your destination chord
to submit. Alternatively, use “Check starting shape” and then “Check held chord”
to check the physical keys down at each step, allowing a shared note to stay held. Sustain-pedal sound is
not treated as a physically held key. Switching app/device, navigating or
playing a demonstration pauses capture.

Without MIDI: turn on On-screen keys, choose notes and Check my choice. This
records a pitch-selection task, separately from keyboard execution. It does
not pretend a clicked chord is a played performance.

Feedback separates chord tones, shape/register, shared pitches and movement.
You can hear your own change, try another voicing, see a suggested answer or
continue. A successful retry never erases an earlier miss from the encounter.
The existing ReviewSchedule supplies review dates; there is no second mastery
score or hidden adaptive model. No timing, articulation, pedal or technique
grade is given here. Chord lab → Follow the changes → Play in time remains the
separate timed practice activity.

SAVING

Session position, hints, answers, detailed practice journal and review changes
are saved in one practice-state.json write. A failed answer save stays available
for “Save answer again”; it does not make another request or duplicate credit.
Committed sessions resume after quitting. Unsaved pending answers exist in
memory only; save them before quitting if storage is failing.

Practice format 5 protects session data from older app writers and migrates
formats 1–4 with prior bytes preserved. Courses remain format 2; scores remain
format 4. One current session and the most recent 20 completed sessions are
retained, with up to 256 responses per session. The existing journal is bounded
to 10,000 attempts. No source book is uploaded and no OpenRouter credits are
needed for this feature.

Open music teaching resources.txt records the verified curriculum shortlist,
reuse terms and possible advanced pathways. No third-party course content was
added to the app in this release.
