# Twenty worked supplementary domain swaps

Each day has two fictional settings for the same musical operation. Show after the core example or use a different story while holding target and score logic. **After Check** means first save the new M/N response. These are not copied songs, real safety signals, movement measurements, cultural rhythms or claims about a person's reaction.

| Day | Worked swap 1 | Worked swap 2 |
| --- | --- | --- |
| 31 | Paper seed shop: four windows → A `X – X X`, quiet second window, three events. | Planet-card set: four images → A `X – X X`, one rest at local 2. |
| 32 | Imaginary book display: A then A → `X – X X / X – X X`, eight places, six events. | Model fruit stall: repeat its invented four-mark A twice → same local rest 2 in each phrase. |
| 33 | Paper ferry timetable: A then B `X – X X / – X X –` → swap whole cards to B then A, five events still. | Cardboard cloud gallery: B then A `– X X – / X – X X` → reorder to A then B without changing cells inside either phrase. |
| 34 | Toy bridge drawing: A then A `X – X X / X – X X` → quiet final local count of phrase 2, yielding `X – X X / X – X –`. | Pretend bakery sign: second A gains one final REST → first phrase three events, second two, eight beat places. |
| 35 | **After Check:** paper orchard E=`X – X –`, F=`– X X –`; E then F → F then E, internal four cells fixed. | **After Check:** invented museum cards G=`X X – –`, H=`– – X X`; G then H → H then G, still eight beat places. |
| 36 | Drawn ribbon label: A then A → replace second phrase local X3+X4 with one LONG(3–4), five full-score events. | Paper rocket scene: first A unchanged → second held ending `X – LONG(3–4)`, same occupied places. |
| 37 | Toy garden gate: A then A has six separate X → A then held A′ has five events, both use eight beat places. | Cardboard lighthouse story: two short ending cards → one wide band in phrase 2; occupied local 3–4 stay. |
| 38 | Pretend post office: `X X – X / X – – X` → second phrase changes local count 2 to REST, eight places. | Drawn ocean window: `– X X – / – X X –` → exact repeat of a different child-made phrase, four beat places twice. |
| 39 | Original child paper-gallery score shown to a willing educator → log actual “score shared,” not “played.” | Original toy-path sound offered to a willing adult only if actually produced and received → log “sound shared,” not assumed feeling. |
| 40 | **After Check:** seed-box P=`X – X X`; second P combines local X3+X4 → `X – LONG(3–4)`, unlike N's held start. | **After Check:** invented market Q=`X X X –`; second Q changes local X3 to REST → `X X – –`, a rest variation, not N's source. |
