# Original call-and-answer score kit

A phrase here has four numbered **beat places**. X is one planned short event; REST is a planned quiet place. The wide divider separates phrase 1 and phrase 2; an arrow above them shows intended turn order. A circle or triangle is an abstract role/source label, **not** a real instrument or person. Read left to right within each phrase and restart local count 1 in phrase 2. Use broad fixed raised cards or a marker board; avoid small loose pieces. No one must sound, sing or interpret this as cultural repertoire.

Six illustrated [A4 practice pairs](print/TEXT-ALTERNATIVES.md) support the following worked plans. Use fresh O/P only on their check days.

### A · An echo with two roles

T = **X REST X REST**, two planned events in four places. Circle calls with T; triangle answers with another complete T: **T | T** has eight beat places and four planned events. An echo here means the second four-place score copies the first exactly. The [A illustrated card](print/call-echo.svg) shows two visible role panels, a thick hand-off arrow and four numbered cells under each panel. The fictional “paper gallery” has no required real sound.

### B · One changed answer mark

Keep first T. In second T only, replace local count 3 X with REST: **T | T′ = X REST X REST / X REST REST REST**. The call has two events, the answer one, three total. Counts 1, 2 and 4 in the reply stay unchanged. See the [B illustrated card](print/changed-answer.svg). T′ means “T changed,” not a new curriculum code or a required musical ending.

### C · A turn arrow, not a performance demand

Place circle above T and triangle above T′ with one arrow across the divider. The arrow shows first then second in a **plan**. It cannot prove two people actually played, or that any audience heard it. The [C turn card](print/turn-arrow.svg) shows role symbols big enough to distinguish without colour. A child can point to the source/role sequence without taking a social turn.

### D · Choose an answer for a musical reason

First phrase remains T. Reply option 1 is changed T′ = **X REST REST REST**, one event. Reply option 2 is a contrasting U = **REST X REST X**, two events. **T | T′** has three events; **T | U** has four. Both use eight beat places. See the [D answer board](print/answer-choice.svg). Children choose a reason such as “I want a single reply mark” or “I want the reply to begin quietly.” No score guarantees a listener will feel a named emotion.

### E · Two sources are a plan

Add circle to T and triangle to T′, or swap the labels while holding all eight rhythmic cells fixed. A symbol can stand for an approved sound source later. It does not itself prove that the source was heard, had a particular timbre, or was made by the child. If locally reviewed, [candidate O](audio/cue-o-two-turns.wav) has two synthetic pure tones at different **pitches**; see exact [event transcript](audio/ASSET-INDEX.md). [E source board](print/source-choice.svg) works completely silently.

### F · Make and label an original pair

On the [F maker/share board](print/make-share.svg), design two groups of four with X/REST marks. The answer can exactly echo the call, change one cell, or contrast in a child-explained way. Add abstract role/source labels and say what the musical plan is intended to do. The adult model **X X REST REST / X REST REST REST** changes local count 2 only in the reply. Record actual sharing only after a willing person receives the child's work; a planned recipient does not count.

The two fresh public check prompts and source patterns are in [STUDENT-CHECKS.md](STUDENT-CHECKS.md), with worked answers in educator-only [key](teacher/KEY-AND-NEXT.md). A correct paper score is partial composing evidence; hearing, controlled timed playing and audience receipt require separate real observations.
