Open after saving the child's first response. These are formative score-planning tasks, not a listening exam, performance measure, emotional assessment or whole Music achievement-standard judgment. A neutral adult can read every public mark but must not name the pattern or choose replacement cards.
Check Gap 1
Track A spreads: its first gap is S and last gap is L, with M between. Track B is even/steady: M–M–M. Both have four identical event identities: fixed L pitch, V planned level, source A and count four. Accept any one accurate hold. The paper cannot establish actual event timing, sound comfort, aural discrimination or a listener's response. If the child identifies A but cannot compare first/last, use a different after-check raised pair with ends separated; preserve the first response.
Check Gap 2
B must become L M S, gathering toward the end: gap 1 changes S→L, gap 2 M holds, gap 3 changes L→S. All four event marks still match A and one another. Accept the child's own musical purpose without a required emotional word. Paper cannot prove real performance, hearing or listener meaning. If B changes a fixed event or middle gap, use a new after-check base to separate event and gap lanes, preserving the first answer.
| Day | Evidence to save | Next invitation |
|---|---|---|
| 121 | First count of four starts and three between-start gaps; selected spacer order. | Contrast a dot with a spacer in a new strip. |
| 122 | Three M gaps and child's reason for even spacing. | Try a single changed gap without changing sound identity. |
| 123 | Child's L–M–S order and first/last comparison. | Compare gathered dots with an even strip. |
| 124 | Child's S–M–L order and held-event explanation. | Present a fresh two-track comparison. |
| 125 | First Gap 1 track labels, first/last evidence, one hold and paper limit. | Offer different after-check tracks. |
| 126 | Child's gap change versus fixed four event marks; physical claim boundary. | Ask whether planned time was ever tested. |
| 127 | PLAN entry, any real playback/recipient source, or NOT TESTED/NOT ASKED. | Keep actual fields separate in a new brief. |
| 128 | Two first child-owned tracks, at least one changed gap and own purpose. | Optional willing reader, private if preferred. |
| 129 | Actual source/child response if encountered; recipient/medium/words if shared. | Keep FE01/FP01 held otherwise. |
| 130 | First B order, two changed end gaps, held middle/events and paper limit. | New after-check base for further practice. |
