MDPE.21:2 - Solution
Design the local architecture that makes the intended distinctions producible, performable, recognizable, selectable, transmissible, and recoverable. These are concurrent concerns in a living practice, not stages that every project performs in one order.
MDPE.21:2.1 - Begin with a representative recurrence
Name one result that should recur after the initial novelty has passed. Examples include:
- dancers can use a changed partnering and timing practice with unfamiliar partners at a social event;
- musicians can learn, rehearse, vary, and perform a rhythmic or timbral language beyond the founding ensemble;
- teachers can develop capability without reducing the style to copied figures or one recorded phrase;
- listeners, partners, judges, curators, or sensing Systems can discriminate a relied-on difference under the conditions where their response changes later Work.
State what continuity must survive and what variation remains valuable. If the project cannot name a desired
recurrence, return to MDPE.1; it may be producing one work rather than developing a style line.
MDPE.21:2.2 - Recover the current reproduction architecture
Follow one actual or representative Music-or-Dance occurrence backward into the conditions that made it possible and forward into the conditions that influence its reuse. Open only the concerns that can change the decision:
| Architecture concern | Practical question |
|---|---|
| Variant production | Which Work enacting composition, choreography, improvisation, arrangement, rehearsal, or tool-supported Methods produces materially different candidates? |
| Performing capability | Which bodily, perceptual, instrumental, ensemble, partnering, or technical capabilities must function during representative Work? |
| Performing configuration | Which Agents, instruments, software, spaces, cues, permissions, and signal, contact, access, control, timing, or coordination relations must obtain together? |
| Recognition | Who must notice which difference, in what conditions, with what capability and observation? |
| Selection and amplification | Which teaching, repertoire, programming, judging, peer-copying, audience, market, or platform relations make some variants more likely to recur? |
| Transmission and reconstruction | Through which lessons, imitation, notation, recordings, examples, models, or joint Work can a receiving Agent reconstruct a Method and perform representative Work that enacts it, or develop a useful receiving variant? |
| Memory and recurrence | Which embodied capability, repertoire, archive, curriculum, instrument setting, venue practice, or recurring event makes later recovery possible? |
| Supporting environment | Which schools, ensembles, venues, platforms, instruments, software, providers, archives, or event series enable or constrain the other relations? |
The table is a set of architecture concerns, not a universal component list and not a first–then process. In one dance performance, bodily coordination, partner response, figure execution, stylistic enactment, event participation, and contribution to a living practice may occur simultaneously at different scales. In one music performance, fingering, phrasing, ensemble coordination, stylistic enactment, presentation, and contribution to a repertoire may likewise occur together.
Use Systems Engineering when the project changes a performer-supporting System, instrument, venue, school,
platform, archive, or other engineered System. Use Method Engineering when the changed subject is a composition,
training, teaching, rehearsal, improvisation, recognition, selection, transmission, or other Method. MDPE.21
adds the Music-and-Dance purpose, distinctions, simultaneous performance concerns, receiving use, and cultural
consequences that make those general engineering results useful here.
MDPE.21:2.3 - Find what currently reproduces the predecessor
Compare the intended recurrence with the current architecture. Look for a relation that repeatedly defeats the new distinction. Typical examples are:
- candidate generation changes, but training and rehearsal still develop the predecessor’s capability;
- performers can enact the distinction, but partners, listeners, teachers, or judges cannot recognize it;
- a workshop produces local success, but receiving Agents cannot reconstruct the practice elsewhere;
- a platform amplifies camera-ready hooks while the project needs partner response, long form, or live musical variation;
- an archive retains records while embodied capability, instruments, venues, or teaching Methods disappear;
- one school stabilizes a useful practice but its authority, access, or incentives suppress valuable variants.
Name the observed relation and the consequence it has for Work. Do not call a whole population, market, platform, or culture “the bottleneck” when the project has not identified a changeable relation.
MDPE.21:2.4 - Develop several architecture candidates
Do not let the first plausible intervention define the architecture. Develop materially different candidates. For example:
| Candidate emphasis | Change considered | What it may reveal |
|---|---|---|
| Capability-first | Change drills, embodied correction, listening practice, rehearsal, or ensemble training. | Whether performers can enact the distinction in representative Work. |
| Recognition-first | Change examples, comparison tasks, partner cues, judging or curation, and how learner, partner, listener, judge, or curator observations are used in later teaching or selection. | Whether a relied-on Agent can discriminate the distinction and use that observation in the next Work. |
| Transmission-first | Change teaching, joint practice, notation, demonstrations, recordings, or reconstruction tasks. | Whether another Agent can reproduce and adapt the practice rather than copy one artifact. |
| Circulation-and-memory-first | Change event recurrence, repertoire, archives, publishing form, access, or retrieval. | Whether later Work can recover the practice under changed people, places, or media. |
| Medium-first | Change instrument, software, camera arrangement, platform, venue, or production System. | Whether the support System enables the intended Work instead of selecting another result. |
| Coupled minimal change | Change two or more tightly linked relations whose separate repair would fail. | Whether the joint change resolves a conflict that neither local repair can resolve alone. |
These are candidate emphases, not prescribed kinds. A useful candidate states the Systems and Methods it changes, the Agents whose Work or capability is involved, the direct signal, contact, access, teaching-use, observation-use, selection, or other relations changed, the authority and consent needed, the expected effect, and the earliest observation that could defeat it.
MDPE.21:2.5 - Select a bounded change and specify its first test
Choose the smallest architecture change that can alter the waiting decision. A project can change a class, tool, event, repertoire, recording practice, platform feature, recognition task, or relation among them. It cannot decide by itself that a wider population has recognized, selected, transmitted, or retained the result.
Specify the representative Music or Dance Work that would test the candidate. The test must vary at least one condition that the style-development claim must survive: performer, partner, ensemble, teacher, venue, instrument, repertoire item, audience, medium, or time. Name the observations of the intended difference and unwanted side effects, and the next decision they can change.
The architecture decision can close with the chosen arrangement and this specified test. Carrying out the
selected change and test is further Work, using MDPE.15 or the applicable direct Method. A claim about tested
recurrence requires observations of the relevant later Work. Keep project choice, performed intervention,
observed change, and later distributed uptake as separate claims.
