MDPE.9:4 - Worked Cases
MDPE.9:4.1 - Human–AI movement generation
A movement-generation project compares model and interface variants with Voguing and Dancehall dancers. High, low, and intermediate fidelity can create different relations between recognizability, dancer interpretation, control, surprise, and tool-development value. A model score alone cannot decide among them.
The project identifies the generated movement material and interface edition, lets dancers improvise with each candidate, records what they could recognize, control, adapt, or reject, and returns separate dispositions for choreographic stimulus and tool design. A low-fidelity candidate may remain useful as a stimulus while a more faithful one serves another use. The reported study supplies a direct co-design Method; another project must not copy its dispositions without new trials.
MDPE.9:4.2 - Three music arrangements
A composer prepares a work for singer, clarinet, cello, and live electronics. The intended relation is antiphonal; breath and a recoverable electronic failure mode matter. Three arrangements differ materially:
- dense spectral doubling preserves pitch content but may mask the antiphonal relation;
- sparse instrumental answers preserve space and breath;
- generated responses allow variation but add latency and recovery demands.
Rendering exposes range and balance. A short rehearsal with the intended musicians exposes breath, cueing, latency, and fallback recovery. The first version can be rejected for the current use, the second retained for an acoustic branch, and the third revised for another trial. Those decisions do not yet select a concert programme.
MDPE.9:4.3 - Balboa, brushes, and articulated weight
The Dance profile illustrates the distinction between a continuous carrier and discrete articulation. A teacher can generate partnered phrase variants in which continuing floor contact and movement remain legato while the weight event appears at contact onset, direction change, weight arrival, or partner-readable pressure.
A pair trial asks both dancers where the weight event became usable. One candidate can be retained for clear partner timing, another branched for delayed articulation, and another revised because free-leg texture displaced the standing-leg pulse. These examples guide candidate design; use separate capability evidence for the named pair.
MDPE.9:4.4 - Ableton comping as a direct-Method stop
Ableton Live’s comping Method retains takes, supports audition, copies chosen portions to a main lane, and
preserves source material. When that Method already returns the takes, auditions, composite, source relations,
and receiving use needed by the project, stop. Apply MDPE.9 only when a broader performance question remains—for
example, when two composites create different breath or ensemble demands, or branches must remain available.
MDPE.9:4.5 - Shimon and the development decision
The reported Shimon case supports a bounded claim: after people supplied a four-measure seed, the robot generated the remainder and performed it on marimba. One generated remainder is not a compared candidate set. The case also does not make the robot holder of the team’s later practice-development decision.
MDPE.9 would become relevant if several identified continuations or gesture variants were tried under stated
musical conditions and the Agent responsible for the development decision returned bounded dispositions.
MDPE.9:4.6 - Duet constraint specifications
One duet rule says that dancer P changes travel direction only after dancer Q produces a readable pressure-change event. Another permits either dancer to initiate while the other preserves contact through the response. The cards describe candidate constraints; they do not make pressure, initiation, contact, or response occur.
During partnered-improvisation trials, the dancers use the cards and observers record whether the proposed relations obtained and remained readable. One rule may be revised because the pressure event is ambiguous; the other may branch because mutual initiation improves recovery while weakening intended asymmetry.
