MDPE.Application:4.3 - Change the receiving condition without confusing the two action rules

The accompaniment is revised: the low right-hand sound must now mark pulse 0 of every eight-pulse cycle. The alternating-attack version fails this condition by construction, even when played perfectly. More practice of that same rule cannot fix the alternating first sound.

Compare a second action rule from chapter 32. Alternate the hands on every pulse, including silent motions, and sound only positions 0, 2 and 5. Capitals below mean audible strokes; lowercase letters mean the indicated hand moves without an audible attack, stopping short or using an appropriately silent motion.

pulse:   0 1 2 3 4 5 6 7
motion:  R l R l r L r l
sound:   x . x . . x . .

Eight is even, so this hand allocation repeats at the next cycle. The first two audible attacks are right-hand strokes and the last is left-hand: it is the chapter-32 smooth-toggle seed. The audible spacing and silence at 6 remain; the timbral organization and movement demand change. Instead of three audible strokes with alternation between them, the performer maintains eight alternating pulse motions. That can help one performer and burden another. Silent movement is not a silent instruction to skip the movement.

In the constructed return, the percussionist first sounds an unintended stroke at 4. The ensemble slows the passage, separates audible from silent motions, then returns to the same receiving tempo and accompaniment. Once the required sound pattern and entry are demonstrated under those conditions, it selects this version for that use and retains the two-cycle version for the earlier arrangement. If the performer cannot obtain the required silent motion reliably in the available preparation time, choose a playable allocation or change the instrumentation, entry demand or rehearsal commitment. A correct table supplies no missing capability.
