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 synchronising a simple tap pattern to a metronome at a comfortable tempo. You will find the pulse, add a pattern, label early and late errors, practise a transition and recover after drift. Speed is not the goal. Target outcome: The learner completes three 20-second trials of a simple rhythm with no lost pulse and fewer than three large timing errors in the final trial. ### Authority and setup conditions - Prepare a four-beat tap pattern at 60–80 beats per minute using a quiet surface or accessible switch - Before the first rhythm synchronisation attempt, write the exact result you will score: Asynchrony, variability, phase correction and perceptual accuracy under declared auditory/visual/haptic and individual/group configuration. - Choose a tempo at which the learner can tap the plain pulse for twenty seconds without rushing. - Use a comfortable hand, foot, switch or movement; clear the area and avoid repetitive force. ### Required or supplied materials - a short metronome pattern at a comfortable tempo. - A metronome with visual, auditory or haptic cue and adjustable safe volume. - A phone video, timing app or observer tally for early, late, missed and extra taps. ## 1. Find the plain pulse Run the cue for eight beats without moving, then tap once per beat for sixteen beats. Why: A stable pulse must be felt before a pattern can be placed on it. Success check: Sixteen taps continue without an extra, missed or doubled beat. Accessible alternative: A visible, captioned or haptic version of “Run the cue for eight beats without moving, then tap once per beat for sixteen beats.” can rehearse the response sequence, but it removes the declared auditory stimulus and is therefore a related activity, not an equivalent attempt at Rhythm synchronisation. To preserve the target, keep the authored sound and adapt only non-target access such as response input, instructions, breaks or support; retain this success check: “Sixteen taps continue without an extra, missed or doubled beat.” Alternative relationship: Related alternative changes trained or measured target Learner notes: ________________________________________________________________________________ Completed: [ ] ## 2. Say the pattern Speak, sign or point the four slots as “tap, tap, rest, tap” while the metronome runs; do this four times before moving. Why: An explicit time grid separates knowing the pattern from coordinating it. Success check: Each rest stays silent and each tap lands in the intended slot. Accessible alternative: A spoken or tactile version of “Speak, sign or point the four slots as “tap, tap, rest, tap” while the metronome runs; do this four times before moving.” can rehearse the response sequence, but it removes the declared visual stimulus and is therefore a related activity, not an equivalent attempt at Rhythm synchronisation. To preserve the target, keep the authored visual stimulus and adapt only non-target access such as response input, instructions, breaks or support; retain this success check: “Each rest stays silent and each tap lands in the intended slot.” Alternative relationship: Related alternative changes trained or measured target Learner notes: ________________________________________________________________________________ Completed: [ ] ## 3. Add the movement slowly Perform the pattern for four bars at the same tempo. Keep the tap light and let the metronome remain audible or visible. Why: Low force and a stable cue make timing error easier to detect. Success check: The pattern remains recognisable and does not drown out the cue. Accessible alternative: Complete “Perform the pattern for four bars at the same tempo. Keep the tap light and let the metronome remain audible or visible.” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “The pattern remains recognisable and does not drown out the cue.” Keep usual aids for Rhythm synchronisation; record each support inside the rhythm synchronisation setup. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 4. Label timing errors After the trial, mark each large error E for early, L for late, M for missed or X for extra. Do not collapse them into “bad rhythm.” Why: Different errors need different timing corrections. Success check: Every visible error receives one of the four labels. Accessible alternative: Complete “After the trial, mark each large error E for early, L for late, M for missed or X for extra. Do not collapse them into “bad rhythm.”” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “Every visible error receives one of the four labels.” Accessible opening check for Rhythm synchronisation: Sixteen taps continue without an extra, missed or doubled beat. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 5. Repair the broken transition Loop only the beat before and after the largest error for six slow repetitions, then return to the full bar. Why: Targeted transition practice avoids rehearsing already-stable beats. Success check: The selected transition is correct on five of six slow repetitions. Accessible alternative: Complete “Loop only the beat before and after the largest error for six slow repetitions, then return to the full bar.” in shorter passes, or use keyboard input, dictation or a support person, while preserving this success check: “The selected transition is correct on five of six slow repetitions.” Use hand, foot, head movement, switch, eye gaze or haptic cueing; score the same time slots rather than demanding one body part. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## 6. Recover without chasing If drift occurs, stop tapping for one bar, listen or watch the pulse, then re-enter on beat one. Do not squeeze extra taps into the gap. Why: A clean reset preserves the time grid better than frantic correction. Success check: Re-entry lands on beat one with the original tempo unchanged. Accessible alternative: A visible, captioned or haptic version of “If drift occurs, stop tapping for one bar, listen or watch the pulse, then re-enter on beat one. Do not squeeze extra taps into the gap.” can rehearse the response sequence, but it removes the declared auditory stimulus and is therefore a related activity, not an equivalent attempt at Rhythm synchronisation. To preserve the target, keep the authored sound and adapt only non-target access such as response input, instructions, breaks or support; retain this success check: “Re-entry lands on beat one with the original tempo unchanged.” Alternative relationship: Related alternative changes trained or measured target Learner notes: ________________________________________________________________________________ Completed: [ ] ## 7. Test one small change After two stable trials, change only tempo by five beats per minute or swap the tapping hand. Repeat one trial and compare error type. Why: One controlled variation tests near transfer without masking what caused failure. Success check: The new trial changes one feature and keeps the pattern and scoring rule constant. Accessible alternative: Complete the same research action — “After two stable trials, change only tempo by five beats per minute or swap the tapping hand. Repeat one trial and compare error type.” — using speech-to-text, text-to-speech, enlarged text, keyboard-only navigation, shorter work blocks or a support person. Preserve this declared check: “The new trial changes one feature and keeps the pattern and scoring rule constant.” Do not convert the research task into capability practice. Alternative relationship: Target preserving when declared check is preserved Learner notes: ________________________________________________________________________________ Completed: [ ] ## Reflection What changed? ________________________________________________________________________________ What remains difficult? ________________________________________________________________________________ What will I repeat, adapt, ask for help with, or stop? ________________________________________________________________________________ --- Completion of this worksheet demonstrates tutorial participation only.
