MDPE.12:4.1 - A Balboa-and-brushes comparison

This constructed project example shows the minimum result; its observations are illustrative project data, not a claim about all Balboa dancers. A teacher must decide whether the B articulation is promising enough to retain as the next brush-and-weight-transfer exercise without requiring a larger step. The subject is one pair’s repeated Dance Work, not a population or a causal mechanism.

For this constructed comparison, the same recorded brush pattern supplies the audible timing reference in every trial. The three instructions keep the same small-step phrase and continuous movement but align each audible brush accent with a different event: A — first floor contact; B — arrival of weight on the supporting foot; C — change of travel direction. These labels identify the trial instructions whose enactment is observed below.

The following observations are obtained under one tempo, one pair, the same eight-bar phrase, and a randomized order of the three articulation variants:

an audio trace gives the audible brush onset for each trial;
side video gives visible foot placement and step size;
the receiving partner reports an ambiguous direction in three of six A trials, none of six B trials, and two of six C trials; and
the performing dancer reports similar effort for A and B but greater effort for C.

The teacher judges B to be the best current exercise candidate because B trials had fewer ambiguity reports than A and C, effort similar to A, and no larger visible step. This is a descriptive within-pair contrast and a practitioner judgement for one phrase. It does not establish that B caused the report difference; random order reduces one possible bias but does not supply a separate causal result.

The next class therefore retains B provisionally and tests it with four unfamiliar partners and two music conditions. The evidence does not support whole-style recognition, social-floor transfer, long-term learning, or the same timing relation for other pairs, tempi, or styles. Reopen the choice if the unfamiliar-partner trials do not preserve the observed contrast or if the audio–weight relation changes with tempo.

MDPE.12:4.2 - Direct Dance-observation Methods

Current sources offer different Methods: kinematic and directed-influence measures, researcher coding and classifier validation, experienced-improviser segmentation and rating, multimodal field inquiry, and participant checking. Each exposes different relations. None alone establishes audience recognition, cultural selection, or long-term transmission.

Choose from the claim. If the question concerns participant meaning or contested interpretation, a force trace is not a substitute for participant access and response.

MDPE.12:4.3 - Comparative Music and rhythm-aware representation

Comparative-Music sources use listening, notation, acoustic features, coded corpora, macro-features, and rhythm-aware sequence comparison. McBride and Fitch aligned many Irish dance-tune variants before examining mutability, substitution, positional conservation, and covariance. The rhythm-aware adaptation matters because a borrowed sequence representation can erase timing distinctions central to the material.

This can support a bounded continuity or transmission claim for those materials and Methods. It does not decide artistic value, performer control, event investment, or current audience recognition.

MDPE.12:4.4 - Institutional visibility versus actual practice

Suppose official standards, university courses, and professional press repeatedly name one engineering Method, while project teams are observed using other Methods and reporting compliance in the official vocabulary. Or suppose academic Dance literature is dominated by ballet while adult social-dance events are much more common in everyday practice. The two source sets describe different cultural processes.

Use the available records and an expert estimate with a stated basis when a large prevalence study is infeasible. Do not report institutional discourse as project use, or sparse informal documentation as absence of practice.

MDPE.12:4.5 - `TYMYLYS`: occurrence, reviews, and process judgement

NDT produced and premiered TYMYLYS. Later reviews, audience conditions, production evidence, and the artistic director’s judgement of the process are different subjects. They can inform a decision about retaining a guest-team production approach without being averaged into “overall success.” None alone establishes cultural retention.

MDPE.12:4.6 - Shimon and Jason Barnes

Reported performances by Shimon and by Jason Barnes with a prosthesis provide bounded evidence about generation, actuation, control, dexterity, coordination, and transfer under stated conditions. Shimon or Barnes performs the bounded Work; the people developing the robot or prosthesis and the performing Agent can be different Agents.

Concert success or media attention does not establish a new style, whole-population recognition, or independent robotic cultural stewardship.

MDPE.12:4.7 - Missing recognition evidence

A proposed event or teaching change claims that a population will recognize an intended distinction. Existing guidance supplies material and observation ideas but no population, comparison task, transfer conditions, or result. Return the missing recognition evidence and blocked decision. Use MDPE.23 if the population must develop the capability; use MDPE.13 if the selection arrangement itself must change.

MDPE.12:4.8 - Direct-Method stop

A musician uses a maintained listening-and-acoustic-comparison Method that already identifies recordings, listeners, competence, conditions, representation, comparison basis, uncertainty, and the mix decision. Use that result directly. MDPE.12 adds nothing unless several result kinds or cultural horizons must remain distinct.
