Space: Room-scale practice space Automated structural checklist: 10 of 10 structural checks present Evidence quality/context: G1; Detailed research depth Automated method-quality band: Comprehensive Method-rating basis: Structure coverage, instruction/check specificity, alternative distinctness, source troubleshooting, comparison depth and whether purpose/check fields are authored rather than derived. Editorial review: Pending manual editorial sign off ## Before you begin - [ ] I read the tutorial authority and stop conditions. - [ ] I have the required equipment/space or a declared accessible alternative. ## Canonical source context This lesson teaches a low-risk coordination routine on a familiar safe instrument: map the movement, practise small chunks, isolate the transition, use a slow pulse, count clean repetitions and increase tempo only after control is stable. Target outcome: The learner performs an eight-event pattern three times at a comfortable tempo with correct order, timing and recovery and no pain. ### Authority and setup conditions - Prepare an eight-note or eight-gesture pattern on a familiar, low-force instrument or accessible controller - Before the first instrumental coordination attempt, write the exact result you will score: Timing, note/gesture accuracy, error recovery and repertoire completion under declared instrument and adaptation configuration. - Confirm the instrument is stable, adjusted to the learner and played at a safe volume. - Choose a pattern below current maximum tempo and range; unfamiliar high-force technique needs a teacher. ### Required or supplied materials - a short safe instrumental pattern at a slow tempo. - A written fingering or movement map, metronome and recording device. - A tally for wrong event, timing break, missed transition, restart and discomfort. ## 1. Map the events Number the eight notes or gestures and write the finger, hand, key, string or control for each before playing. Why: A visible map separates memory errors from movement errors. Success check: The learner can point through all eight events in correct order. Accessible alternative: Complete the same research action — “Number the eight notes or gestures and write the finger, hand, key, string or control for each before playing.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “The learner can point through all eight events in correct order.” Do not convert the research task into capability practice. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 2. Rehearse without sound Move through events 1–4 slowly without producing sound, then 5–8. Keep contact light and posture comfortable. Why: Silent rehearsal exposes awkward paths without adding timing and sound pressure. Success check: Both four-event chunks occur in order without force or lost position. Accessible alternative: A supported, seated, reduced-range or slower version of “Move through events 1–4 slowly without producing sound, then 5–8. Keep contact light and posture comfortable.” is equivalent only when it keeps the same trained or measured target, declared configuration and success check: “Both four-event chunks occur in order without force or lost position.” If any of those change, record it as a related alternative rather than an equivalent repetition. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 3. Play two chunks slowly Play events 1–4 and 5–8 separately at a tempo where every event is accurate. Stop after each chunk. Why: Short accurate chunks reduce repeated whole-pattern failure. Success check: Each chunk has two clean repetitions before joining. Accessible alternative: Complete “Play events 1–4 and 5–8 separately at a tempo where every event is accurate. Stop after each chunk.” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “Each chunk has two clean repetitions before joining.” Keep usual aids for Instrumental coordination; record each support inside the instrumental coordination setup. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 4. Isolate the join Loop events 4–5 six times with a full reset between attempts. Mark wrong event, hesitation or excess force. Why: The boundary between chunks is often the real coordination problem. Success check: The join is clean on five of six attempts at the chosen tempo. Accessible alternative: A supported, seated, reduced-range or slower version of “Loop events 4–5 six times with a full reset between attempts. Mark wrong event, hesitation or excess force.” is equivalent only when it keeps the same trained or measured target, declared configuration and success check: “The join is clean on five of six attempts at the chosen tempo.” If any of those change, record it as a related alternative rather than an equivalent repetition. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 5. Join under a pulse Set the metronome below the error threshold and play all eight events once. Do not speed up after the midpoint. Why: A steady external pulse reveals timing drift. Success check: Order and beat placement remain stable through event eight. Accessible alternative: A supported, seated, reduced-range or slower version of “Set the metronome below the error threshold and play all eight events once. Do not speed up after the midpoint.” is equivalent only when it keeps the same trained or measured target, declared configuration and success check: “Order and beat placement remain stable through event eight.” If any of those change, record it as a related alternative rather than an equivalent repetition. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 6. Recover from one error If an event fails, pause on the next planned rest or stop point, reset and restart from the nearest chunk boundary. Do not scramble ahead. Why: A planned recovery prevents one miss from cascading into force and timing errors. Success check: Recovery begins from a named boundary without rushing. Accessible alternative: Replace small or visual-only information with enlarged text, high-contrast display, spoken description or tactile/verbal cueing while preserving the same decision and success check. Keep usual aids for Instrumental coordination; record each support inside the instrumental coordination setup. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 7. Earn a small tempo change After three clean full patterns, raise tempo by no more than five percent and attempt once. Return to the old tempo if any error returns. Why: Small, reversible progression protects accuracy from tempo-driven breakdown. Success check: The higher tempo is kept only if the same accuracy and comfort rule is met. Accessible alternative: Complete “After three clean full patterns, raise tempo by no more than five percent and attempt once. Return to the old tempo if any error returns.” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “The higher tempo is kept only if the same accuracy and comfort rule is met.” Accessible opening check for Instrumental coordination: The learner can point through all eight events in correct order. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 8. Test later retention After at least 48 hours, play once before rehearsal and compare order, timing, recovery and symptoms with the final first-session trial. Why: A delayed first attempt distinguishes retained coordination from immediate repetition. Success check: The later trial is preserved before warm-up practice changes it. Accessible alternative: Complete the same research action — “After at least 48 hours, play once before rehearsal and compare order, timing, recovery and symptoms with the final first-session trial.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “The later trial is preserved before warm-up practice changes it.” Do not convert the research task into capability practice.
