RHY.10:4.2 - Distinguish placement, pace and grouping before correcting
Compare the intended relation with the received or performed one.
- A roughly constant displacement at an otherwise matching pace calls for a placement question.
- A displacement that accumulates across comparable events calls for a pace, period or changing-delay question.
- A correct local beat with a wrong entrance can call for cycle position or grouping.
- A missing response during sustained sound or silence can call for a continuing reference or an unresolved duration.
These are diagnostic contrasts, not exclusive causes. A changing cue delay can resemble a tempo error. An intended expressive displacement can resemble accidental lateness. Compare the relevant passage under a small useful change rather than infer a mechanism from one timestamp. When source pace and cue delivery remain plausible alternatives, compare source events with the received cues using an available independent reference or a suitable alternative cue channel. Obtain an additional timing observation only if that distinction changes the correction.
State the relation worth preserving: coincidence, a deliberate offset, alternation, shared phrase arrival or another recognizable coordination. The allowed variation comes from this use and the performing conditions.
