Each pair changes the fictional surface context while retaining that day's music operation. These are worked examples for later practice or an alternative to the core story, not extra assessment prompts. “After Check” means collect the first fresh I/J response before showing either row. None is a real help signal, scientific rolling/slide result, song, cultural rhythm or predicted listener reaction.
| Day | Worked swap 1 | Worked swap 2 |
|---|---|---|
| 11 | Paper post office: four drawn envelopes → X X X X across numbered 1–4, one imagined pulse per picture. |
Model vegetable stall: four display trays → X X X X; the four planned beat places stay equally spaced. |
| 12 | Cardboard greenhouse door: mark the opening picture → star at 1 above X X X X, still four beats. |
Pretend astronaut checklist: first drawing is highlighted → one accent star at count 1, no extra X. |
| 13 | Paper bus timetable: slow four-picture browse → 4 X with longer equal gaps; faster browse → same 4 X with shorter equal gaps. | Toy-library book covers: two rows each hold four X → SLOW has wider beat spacing, QUICK shorter; loudness is not specified. |
| 14 | Drawn parcel path: highlight arrival → move one star from 1 to 4 over fixed X X X X. |
Cardboard fountain model: highlight finish frame → first-star plan becomes last-star plan; four X remain. |
| 15 | After Check: garden-card row stars count 1, wants emphasis at count 3 → move one star 1→3, all four X held. | After Check: pretend lighthouse display stars count 4, wants emphasis at count 2 → move one star 4→2; four X, one star. |
| 16 | Paper kite shop: PULSE X X X X; one reply card at 3 → ANSWER – – X –, aligned under the third kite. |
Drawn picnic list: four pulse pictures, reply at picture 3 → PULSE four X / ANSWER – – X –, no real person replying. |
| 17 | Model fruit queue: answer after picture 2 → – – X – at count 3; later choice after picture 3 → – – – X at 4. |
Pretend planet board: pulse remains X X X X; move one answer X from 3→4 and replace count 3 with rest. |
| 18 | Child-designed paper bridge: pulse X X X X, choose early reply at 2 → ANSWER – X – –; state “early answer.” |
Drawn rain-window story: pulse four X, choose answer at 4 → – – – X; state “answer at finish.” |
| 19 | Original book-cover score with answer at 2 → if actually shown to a willing educator, log “score shared,” not “played.” | Original toy-track score with answer at 4 → if optional sound actually reaches a willing adult, log “sound shared,” not the adult's presumed feeling. |
| 20 | After Check: paper orchard pulse X X X X, answer initially all rests, brief “reply after pulse 1” → ANSWER – X – –. |
After Check: pretend train-board pulse four X, brief “reply with pulse 3” → ANSWER – – X –; different from J's after-third condition. |
