The invented lanes are pitch L/H (low/high), electronic source A/B (circle/striped square), and planned level V/S (very soft/soft, one/two dots). Large fixed numbered places and raised labelled marks make the score accessible without colour, speaker, screen or printer. A neutral adult reads or moves cards only as the child directs. A written score meets planning/reading targets, not actual hearing, performance or comfort. Candidate sound has a separate human-listening/device-volume gate. Fresh-check descriptions provide the public score but not the worked answer.
A · Three independent Music keys
File: print/three-keys.svg / print/three-keys.pdf. Exact content: Pitch L/H, invented source A/B, planned level V/S have separate words, icons and one-event lanes. Verbatim printed text in layout order: SUBJECTNEST · FOUNDATION MUSIC | Original three-lane score · no-sound route | A · Three independent Music keys | PITCH L/H SOURCE A/B PLANNED LEVEL V/S | One mark in one place may change; the rest stay. | ONE EVENT HAS THREE SEPARATE MARKS | PITCH | L = LOW | H = HIGH | SOURCE | A = CIRCLE | B = STRIPED SQUARE | LEVEL | V = VERY SOFT | S = SOFT | Choose one mark from each lane for one event. | Cards show a score plan, not actual hearing. | Original resource · CC BY 4.0 · exact alternatives in pack. Tactile/no-print alternative: Prepare three labelled fixed lanes. Low/high has a raised baseline with dot low/high; A is circle, B striped square; V has one raised dot, S two. Child selects one per lane.
B · One seed, two takes
File: print/two-takes.svg / print/two-takes.pdf. Exact content: Four L/A/V first-take cards; second take is identical except place 2 level V becomes S.

Tactile/no-print alternative: Build two fixed four-place raised strips with three lanes per place. Preserve first row L/A/V; in second row replace only place 2 one-dot V with two-dot S.
C · Hold and change
File: print/hold-change.svg / print/hold-change.pdf. Exact content: Four L/A/V first-take cards; second take is identical except place 4 source A becomes B.

D · Which lane changed?
File: print/choose-edit.svg / print/choose-edit.pdf. Exact content: Three single-event pairs: LAV to HAV, LAV to LBV, LAV to LAS; one pitch, one source, one level edit.

File: check/fresh-y.svg / check/fresh-y.pdf. Exact content: First LAV/HAV/LBV/HBS; revised LAV/HAV/HBV/HBS. Child finds the one differing mark independently. Verbatim printed text in layout order: SUBJECTNEST · FOUNDATION MUSIC | Original three-lane score · no-sound route | Fresh Y · Find one unfamiliar edit | PITCH L/H SOURCE A/B PLANNED LEVEL V/S | One mark in one place may change; the rest stay. | FIRST TAKE · READ EVERY PLACE | PLACE 1 | P: L | SRC: A | LVL: V | PLACE 2 | P: H | SRC: A | LVL: V | PLACE 3 | P: L | SRC: B | LVL: V | PLACE 4 | P: H | SRC: B | LVL: S | REVISED TAKE · FIND THE ONE EDIT | PLACE 1 | P: L | SRC: A | LVL: V | PLACE 2 | P: H | SRC: A | LVL: V | PLACE 3 | P: H | SRC: B | LVL: V | PLACE 4 | P: H | SRC: B | LVL: S | Name lane, place and old/new mark. | Name something that stayed the same. | What can paper not prove about real sound? | Original resource · CC BY 4.0 · exact alternatives in pack.

Tactile/no-print alternative: Make two identical raised four-place strips with the listed triplets. Child chooses one mark in the second strip to replace; keep the other eleven fixed.
Evidence limit: The paper/raised score shows intended and revised marks. Actual sound, aural perception, comfort, community context and audience receipt need their own observations.
