MDPE-PERFORM — Create alternatives and prepare a performing whole

• Situation: An attractive arrangement or movement candidate works in a rendering or isolated demonstration, but its live performer and coordination demands remain unsettled.
• Question: Which candidate can serve the intended performance, and which relation must be repaired before relying on it?
• First useful result or honest blocker: Candidate dispositions tied to a performer-involving comparison, or the unavailable performer or condition that prevents that comparison.
• Start with: MDPE.9 with the intended use from MDPE.1. If the candidate is already selected, enter at the limiting capability in MDPE.10 or the uncertain interaction in MDPE.3.
• Stop or return: Stop when the present creation or performance decision has the result it needs. A changed venue, instrument, performer, or receiving use reopens the contribution that depends on that condition.

MDPE.9’s constructed music example compares three arrangements for singer, clarinet, cello, and live electronics. The intended relation is antiphonal: the participants must hear and answer one another, with room for breath and recovery from electronic failure. Dense spectral doubling, sparse instrumental answers, and generated responses pose different demands. A rendering can expose range and balance; a short rehearsal with the intended musicians can expose breath, cueing, latency, and recovery.

Suppose that rehearsal shows that the dense version masks the answers, the sparse version preserves the desired space, and the generated responses arrive too late for the intended exchange. Those observations can reject the first candidate for this use, retain an acoustic branch, and return the electronic branch for revision. For a further electronic trial, the musical requirement and failed timing relation guide MDPE.3: configure the cue and signal path, identify who can detect a missed response, and provide the recovery the performers need. Test that interaction together. If a performer cannot make the required response even with an adequate cue and setup, MDPE.10 addresses that capability instead.

MDPE.11 concerns how musicians realize the prepared material and steer its permitted live variation. If a trial shows that dropping the electronic response and using an acoustic answer sustained the exchange, preserve that observed fallback and its conditions for the next decision. MDPE.5 asks whether production and presentation let the intended recipients encounter the same musical relation: a successful monitor mix for the performers can still leave the audience unable to hear the answers.

If the next venue changes audibility or latency, use MDPE.6 to decide whether the existing result can be used, revised, or branched for that venue. Return the affected cue, sound, or performance result for repair. A working acoustic branch can remain available while the electronic branch is revised; a stored score alone does not establish that its musicians and setup are available.
