RHY.12:4 - Solution

RHY.12:4.1 - Choose the relation to develop in the intended passage

Start with a recognizable attempt and the intended continuation. Select the relation that must become available: keeping a reference through silence, changing articulation without changing the underlying movement, coordinating a phrase with a different grouping, entering from a preparation cue, or correcting displacement while keeping the intended pace.

Use RHY.1 when several explanations of the difficulty remain plausible. Establish a demonstrable target, including a permissible variant when the practice allows one. A learner should be able to hear, see or otherwise recover what is to change. A numerical timing tolerance is useful only when the receiving task needs it.

Locate the limiting contribution within the performed whole. A turn may require balance throughout a rotation; musical articulation may require control of release while the hand continues moving. Strength, sequence memory and successful counting do not substitute for those contributions. Obtain missing bodily, instrumental or perceptual instruction from the relevant practitioner. Continue an encompassing activity only under conditions the performer can manage.

RHY.12:4.2 - Construct an exercise that preserves that relation

Keep enough of the passage to include preparation, the troublesome relation and its continuation. Make one useful change to expose or support the action, rather than assuming that making everything slower or easier preserves the task.

RHY.3 and RHY.9–RHY.11 supply the underlying performance constructions. The exercise develops the learner’s ability to carry out the selected construction. If a representation omits a needed duration or grouping, repair that input through RHY.5 or RHY.6; additional repetition cannot recover information that was never supplied.

Choose assistance by its contribution. A beat gesture can keep a reference available while the learner articulates a phrase. It does not by itself say whether an unarticulated beat contains sustained sound or silence. A recording can supply timing but cannot respond like a live partner. Demonstrate the relation using the assistance that is actually available.

RHY.12:4.3 - Perform, locate one changeable action, and retry

Use the HCD.9 feedback-and-retry method on the selected rhythmic action. Listen or watch for the relation itself: whether the reference continues through the phrase boundary, the release occurs before the silence, the accent preserves the continuous motion, or the response corrects the intended displacement.

Give feedback the learner can act on in the next attempt. For example, demonstrate the continuing gesture during the phrase restart instead of saying only “keep the rhythm.” If correction during performance would interrupt the target coordination, use a short attempt, feedback and another attempt.

Separate a problem in interpreting the target from a problem in performing it. The learner may reconstruct the phrase correctly yet lose it when moving, or move fluently to a different reference. Change the demonstration or action practice accordingly.

Stop or reduce the attempt when continuing would defeat the available technique, support or agreed operating limits. Fatigue, a lost sightline or unsuitable equipment may call for a changed condition rather than more repetitions.

RHY.12:4.4 - Rejoin the contribution and vary what later use requires

Return the developed contribution to the passage. Observe it while the encompassing action and other constituent actions occur together. A successful isolated accent, count or turn remains an intermediate result until the needed combination is performed.

Choose variation from the intended use. A passage used at several tempos needs practice across the relevant physical demands; a partner-dependent passage needs responsive interaction; entry at different cycle positions requires recovering the reference from those entries. Hold other consequential conditions stable when doing so helps identify what is failing.

Use HCD.10 to choose repetition, variation, spacing or interleaving. The amount and order of variation depend on the learner and the target contribution. When a change destroys an action still being acquired, a stable version can be the useful next practice. When a fluent familiar version conceals a needed choice or adaptation, introduce that change.

Changing tempo changes the time available for movement, preparation and recovery. Check that the altered passage still exercises the intended relation. A slowed turn may call for different balance control; a faster stroke may exceed the available recovery time. Return such a new prerequisite to its supplying technique rather than calling it merely another count.

Retain assistance that belongs in the intended performing arrangement. If later use requires performance without it, reduce its contribution deliberately and test that use through RHY.13. Removing a needed accessibility aid or the instrument itself changes the task and may change the performing whole.

RHY.12:4.5 - Keep the result at the scope obtained

Retain the useful exercise, correction and conditions in a form sufficient for the next practice. An agreed demonstration may suffice. Name what the learner now performs and which reference, cue, partner or tool still contributes to it.

A local improved attempt supports a local continuation. Use RHY.13 when the next decision requires an unfamiliar condition, later retention or performance without a selected support. Use RHY.14 when the unresolved question concerns how to observe performance or distinguish it from a partner’s or listener’s response.

Stop when the next practice or performance move is clear. Reopen the affected exercise when the passage, learner, support or physical demand changes; retain exercises and results whose conditions still fit.

Local mantra: choose the failing relation; make it practicable; correct an observable action; rejoin the passage; vary for the intended use.
