RHY.9:4 - Solution
RHY.9:4.1 - Recover the contributions and their receivers
Take a short passage containing the difficulty, including its entry and continuation. Identify what must continue, what must be articulated, who produces each contribution, and who needs timing information from it. RHY.2 and RHY.3 supply these distinctions when they are unresolved.
For each consequential cue, ask what its receiver must learn: the next entry, a cycle position, an approaching change of pace, a release, or permission to recover at a later landmark. Retain an already shared convention or demonstrate the intended cue. The same head movement can otherwise be read as an accent, a tempo change or preparation for an entrance.
A solo performer may use an internal reference. A partner can use it only through some accessible consequence. Add an external cue only where that receiving need exists.
RHY.9:4.2 - Allocate production and cueing without losing another contribution
Assign the required sound, movement and cue actions to available performers or means. Inspect their overlap in the passage. A hand making a reference gesture may also be needed for an instrumental stroke; a performer reading a score may not see a small peripheral movement.
Choose a concrete repair: expose an existing preparatory movement, change the receiver’s access, move the cue to another available channel, reassign a contribution, or simplify a conflicting articulation. Preserve the rhythmic and stylistic relations the passage needs. More or larger signals are useful only if the receiver can use them without losing another task.
Use familiar, appropriately supported bodily or instrumental actions. If the proposed allocation requires a technique the performer does not have, return that capability question to RHY.12 instead of treating the assignment as its realization.
RHY.9:4.3 - Make the information usable before the dependent action
Trace the needed relation from cue production through availability and interpretation to preparation and the receiving event. A cue may announce a future event; waiting for that event’s sound would provide different information at a different time. RHY.4 helps distinguish the physical event from the moment or feature the receiver uses.
For a controller or a measured arrangement, compare available advance time with the applicable delivery and preparation times. Include variation where it matters. If the receiver can prepare and wait for a known target time, enough advance information can solve a problem that reacting to the final attack cannot.
For ordinary rehearsal, a clear preparatory gesture followed by a short joint trial may answer the question without timing measurements. Seek a delay estimate only when its possible values would change the arrangement. A precise command timestamp alone does not establish when the action or usable cue occurs.
RHY.9:4.4 - Try the receiving relation while the passage continues
Use the arrangement in the part of the passage where the receiver needs it. Observe whether the receiver obtains the intended information, prepares the contribution and continues the other required actions. Compare with the troublesome arrangement when that contrast can localize the remaining difficulty.
Keep cue availability separate from correction: a visible gesture can be available while performers still disagree about which beat it marks. RHY.10 resolves that reference and adjustment question. If adding the cue disrupts another simultaneous contribution, use RHY.11 to resolve the joint relation.
Include a familiar recovery at a recognizable later point if entry is missed. Do not demand a hurried catch-up that defeats the available technique or support. Existing domain limits and stopping conditions govern the trial.
RHY.9:4.5 - Retain the useful arrangement and its scope
Keep the allocation, cue meaning and access that answer the receiving task. Preserve the conditions that matter—such as sightline, tempo, preparation, equipment or a continuing support gesture.
A calculation can justify a trial; an observed local success can justify retaining that arrangement in comparable use. Wider reliability and transfer remain separate questions. Stop when the next performance decision is possible, or name the unavailable cue, action or capability that prevents it.
Reopen the affected allocation or cue relation when the passage, performer, channel, placement, tempo or preparation changes. Reuse the relations those changes leave intact.
