RHY.Preface:5 - Archetypal Grounding - Connected uses and consequential returns

These cases stipulate their observations to demonstrate decisions. They are not reports of measured training effectiveness.

RHY.Preface:5.1 - An ornament interrupts a partnered figure

A pair can perform a familiar passage. Adding a foot ornament leaves the recorded contacts on the count, but the partner loses the next transition. Under RHY.1 they compare the familiar and ornamented attempts rather than start by demanding more accurate counting. They find that the ornament interrupts the continuing movement which made the transition readable.

RHY.2 keeps contact, continuing movement and partner-read timing distinct. RHY.3 suggests preserving the continuing contribution while changing the articulation. RHY.4 checks the timing of the cue the partner actually uses. The pair chooses a smaller ornament through RHY.8 and arranges its cue through RHY.9; RHY.10/.11 coordinate the shared reference and the concurrent contributions.

In the stipulated next attempt, the partner can use the transition. That supports this variant at the tried pace and with this pair. It supplies no answer about a faster pace or another partner. RHY.13 is needed only if such a changed-condition answer matters.

Now suppose a related rotating figure still fails. The dancer has enough strength to support the body and remembers the figure, but cannot maintain balance during the turn. At that moment, balancing constitutes part of turning, and turning constitutes part of performing the figure with a partner. These are connected works at several levels, not successive tasks or extra rhythmic lines. Reducing the turn permits an exercise; its success does not establish the original figure. RHY.12 returns the balancing contribution to appropriate technique instruction, then restores it to the turn and figure. The already usable ornamented passage remains available.

RHY.Preface:5.2 - A syllable sheet survives, but a phrase does not

A group receives a syllable sheet and a recording. The sheet shows attacks at the beginning of a two-second cycle and at the beginning of the next cycle. The recording supplies an additional requirement: sound continues for the first second and stops for the second. RHY.2/.5/.6 preserve that duration and rest through an available demonstration or explicit representation; a beat gesture alone does not supply the release time.

The receiving group needs access to the recording and someone who can demonstrate the convention. C.36.RP locates and makes those contributions obtainable. MDPE.17 arranges receiving performance. RHY.9/.10 allocate the voice and reference, and RHY.12 practises the required continuation and release.

Suppose the group next reproduces and deliberately alters the phrase without the demonstrator. This is a useful receiving result under those conditions. RHY.13 would select a later retention probe only if a later independent use requires that answer. MDPE.18 keeps the source claim modest: the recording establishes this realization, not an otherwise undocumented origin or lineage.

For continuation, MDPE.19 asks whether the recording, instruction and suitable practice remain available to the next users. Naming another person who can give the demonstration repairs one present access dependence; the plan still needs revision if that contribution becomes unavailable. One receiving success does not establish population-wide survival of the practice.

RHY.Preface:5.3 - More appearances do not yet explain a practice’s future

A dance group is choosing whether to replace a familiar rhythmic variation with one appearing in more recent videos. Through MDPE.20 it bounds the question: what should this group’s next teaching programme retain? RHY.2/.7 distinguish the variants by the relation used in the figure, not merely their shared style label. The group already has an adequate demonstration of each.

Suppose its available observations show that the new variation is convenient in a stationary passage, while the familiar one supplies a readable transition into travel. Recent videos concentrate on stationary passages. Increased appearances are therefore compatible both with changed opportunities for performance and with a shift in what videos select. They do not establish a general superiority or a future attractor.

RHY.8/.9 make both variants available in the relevant arrangement. The group retains each for the passage where it has a demonstrated use and teaches the difference. This decision does not require first resolving the population mechanism. If a later preservation decision depends on whether practitioners are losing the familiar method, MDPE.20 selects a useful observation of access and receiving performance; a count of visible clips would not answer that different question.
