Read top to bottom. Six shared beats 1–6 left to right, A then B each column. A local idea 1–4 at shared 1–4, done 5–6; B initial wait 1–2 then local idea 1–4 at shared 3–6. Circle=A short sound, square=B short sound, dash=wait, question=undecided; colour redundant. Compare each A idea decision with B decision two columns later, including waits. Four-beat idea windows overlap 3–4 even when no sounds coincide; both sound only at paired active marks. Copy rhythm decisions, not source/pitch/level. No-sound plan does not prove hearing/timing/child performance or actual receiver/audience. Actual supplied score/source response only narrow author-purpose opportunity, not full people/community coverage.
A · Same idea, later start
File: print/echo-key.svg / print/echo-key.pdf. Exact linear content: A starts its four-beat idea at shared 1, B starts the same four sound/wait decisions at shared 3 after two waits.
