RHY.1:4 - Solution

RHY.1:4.1 - Recover the failed contribution

Ask what someone was trying to do and what became difficult. Locate an instance: which phrase, transition, entrance or repeated motion; who performs it; who needs its result; and under which music, tempo, contact or equipment conditions.

Replace a broad judgement with an observable difficulty. “The rhythm is bad” might become “the second player cannot enter after the fill,” or “the partner cannot tell when the dancer has finished transferring weight.” Retain the broad artistic intention as a reason for the work; the narrower question identifies something that can be changed.

Separate the intended result from the available observation. A footfall recording can show audible contacts. A partner’s report can identify an unclear felt transition. Which one matters depends on the contribution being sought.

RHY.1:4.2 - Form the rhythm-specific alternatives

Consider only alternatives that would change the correction. Useful distinctions include:

• the pace drifts, or the pace is stable but the performer is displaced relative to a reference;
• the needed events or their order are wrong, or those events occur in the required order but their grouping or accent cues a different entrance;
• the physical action itself is late, or it occurs on time but becomes usable as a cue to the receiving participant later;
• a continuous movement is lost while individual articulations remain correctly placed;
• the component action works alone, or it fails when combined with a partner, another rhythmic layer or a required bodily contribution.

These are recurring comparisons, not a complete classification. Use the one suggested by the actual difficulty. Causes can combine: correcting a sequence may leave its grouping unresolved, and a physical delay may coexist with delayed recognition. If the case gives no reason to choose between explanations, retain the uncertainty.

RHY.1:4.3 - Choose a contrast that separates the alternatives

Repeat a manageable passage while changing one consequential condition. For example, keep the sequence and pace while changing the sound used for an accent; compare the transition with and without its ornament; or compare the same movement alone and with a partner who must respond to it.

State what each result would change. For a sequence/grouping question, recover the events and order first; if they match the required sequence, change only the grouping or accent cue and compare the entrance. A corrected sequence and a corrected grouping answer different remaining difficulties. For a timing question, compare the physical event with the moment the recipient can use it: a late physical event calls for production or delivery correction, while a later usable cue despite an on-time event calls for the receiving-timing comparison. If both versions drift progressively, inspect pace or reference correction. If only one timbre seems late despite the same physical start times, inspect the sound’s temporal shape and the listener’s alignment in RHY.4. If the basic motion continues until an accent is added, inspect their coexistence through RHY.3.

Keep the conditions needed to reproduce the difficulty. An isolated slow action may reveal a constituent skill, but success there leaves its use at performance speed unresolved. Conversely, do not force a full performance when a simpler, comfortable comparison answers the present question.

RHY.1:4.4 - Select the next result, with its limits

Use the comparison to choose a bounded next move:

• select the relevant changes and their relations through RHY.2;
• change articulation while retaining the required continuous motion through RHY.3;
• distinguish and align the relevant timing events through RHY.4;
• agree which cue supplies the shared reference, change the allocation of performers or instruments, or practise the limiting coordination when the contrast identifies that need.

An existing observation can be enough to make that choice. Collect another measurement only if its possible result could change the action or the reliance placed on it. When evidence is insufficient for a causal explanation, a reversible trial may still be worthwhile; describe it as a trial.

Carry forward the passage, receiving use, observed contrast and unresolved condition only as far as another participant needs them. A spoken rehearsal instruction can be sufficient.
