MDPE.19:0 - Use This When

Use this pattern when one successful performance, surviving record, famous name, or remaining expert is being treated as proof that a Music-or-Dance practice can continue.

The practical question is:

Can the named Music-or-Dance variant still be reproduced for the intended use when a credible performer, partner, teacher, instrument, venue, organizer, software, or context change occurs—and what should we change if it cannot?

Typical situations include:

  • a dance school depends on one teacher-organizer and does not know whether another teacher can run the class and social practice;
  • an ensemble can perform a work only with one specialist or rare instrument;
  • an archive contains recordings and notes, but no current performer has reproduced the practice;
  • a festival, competition, platform, or school keeps a style name visible while the Work that once reproduced it has changed or disappeared; and
  • a robotic or AI Music project retains code and recordings while the hardware, runtime, calibration, operator capability, or performance Method can no longer be assembled.

The gain is not a label such as alive, viable, or lost. The gain is a usable account of what sustains reproduction, what dependence matters to the intended horizon, and whether continuation, a targeted change, inquiry or local retirement warrants its burden.

Use direct repertoire, teaching, rehearsal, preservation, reconstruction, instrument-maintenance, software-maintenance, event-production, community-stewardship, deprecation, or retirement Methods without this pattern when they already return the needed continuation decision. Use MDPE.19 when the project still confuses a record, one occurrence, one bearer, or one provider decision with continuation of a practice.

Use another pattern when the live difficulty is narrower:

  • MDPE.18 for source-traceable memory and lineage evidence;
  • MDPE.17 for receiving enactment and source contribution;
  • MDPE.10 for developing performer capability;
  • the applicable direct Method for carrying out and testing an already selected local change;
  • MDPE.20 for several possible future cultural trajectories; or
  • MDPE.5 for producing one performance occurrence.
