- Welcome · 3 min. Four equal places, one chosen sound source and a first/revised pair; this is music making, not the integrated paper-ring test.
- Model · 4 min. First take has
L A Vat all four places. On the second, change only place 2's level V→S. Leave all pitch/source cards and all other levels where they are. - Try together · 5 min. Child compares matched places, points to the one changed mark and names the two lanes held steady. Use raised overlays or neutral verbal reading.
- Child choice · 7 min. Child selects first or revised take for an invented toy-door moment or plain phrase, explaining a personal musical intention. An alternative one-mark change is welcome on a blank copy.
- Notice · 4 min. Save both rows and the stated one-mark edit. Do not describe a heard dynamic contrast unless an approved sound was actually tried.
- Close · 2 min. Next we make the “what stayed” evidence easier to see.
