RHY.11:5 - Archetypal Grounding

RHY.11:5.1 - Two against three, then a resource conflict

In a constructed six-unit cycle, part A has actions at 0 and 3; part B at 0, 2 and 4. The next cycle begins at 6.

A preserves two equal intervals of three units; B preserves three equal intervals of two. The joint sequence has successive gaps 2, 1, 1 and 2. Counting or displaying the six units makes their relationship inspectable without making A adopt B’s grouping.

Suppose one mechanism must realize all events and its supplied limit requires at least 1.5 units between successive actions. Even if coincident A/B events can be realized by one action, the one-unit gaps conflict with that limit. Both separate parts satisfy it; their single-mechanism combination does not.

Allocating A and B to two suitable mechanisms removes this particular conflict: their own intervals remain three and two. The calculation returns a compatible allocation for a joint trial, not proof of a human’s two-hand skill or a completed robot performance.

RHY.11:5.2 - Phrase accents need not follow every beat gesture

Nelson’s Solkattu Manual uses a three-beat gesture cycle with a three-syllable phrase at different rates. Consider its two-syllables-per-beat relation in beat units.

The gestures mark 0, 1 and 2, with the cycle restarting at 3. Syllables occur at 0, 0.5, 1, 1.5, 2 and 2.5. The three-syllable phrases begin at 0 and 1.5. Thus the second phrase starts between gesture beats.

Suppose a learner already performs both contributions alone. In the first constructed joint attempt, they restart the phrase at every gesture and lose the three-syllable grouping. An aligned display shows the two phrase starts across one gesture cycle; a familiar demonstration preserves that relation. In a subsequent stipulated attempt, the learner keeps the three gesture beats, both phrase groups and the return at 3.

Retain that supported combination for this rate. Its result is joint coordination with the given support. Removing the display, changing rate or performing a longer passage changes the later question; it is not covered by the stipulated attempt.

RHY.11:5.3 - Keep a continuous course while an accent crosses it

A constructed passage combines a familiar four-beat swell with an articulated accent at the third beat. The swell must continue rising until the fourth beat; the accent must not restart that course. The performer has the relevant safe instrumental technique.

Suppose separate attempts preserve the swell and place the accent correctly. In the first combined attempt, the accent causes an audible restart. Reducing the accent’s size within the already learned technique yields a second attempt in which the swell continues, the accent remains recognizable at the third beat, and the following release is retained.

Keep the second combination locally. Coincidence of attack marks would not distinguish the two results: the continuous course is the deciding relation. RHY.3 supplies a new carrier/articulation construction if no available means retains it.
