# Foundation Music / Queensland Prep · Weeks 31–32

Ten optional **25-minute** Term 4 sessions, Days 151–160. Children make a short **two-part accompaniment**: A's four-beat backing comes round again exactly, while B tries a different four-beat idea in round 2. The practical outcome is an own tiny duo for an invented paper book, picture show, toy scene or music by itself. A learner may make a reviewed familiar quiet sound, direct willing adult makers, read/shape broad cards silently, keep private or pass. Two rounds are enough; no endless looping or required performance.

This combines earlier phrase-repeat and two-part work into **a repeated backing under a changing part**. [Weeks 27–28](../../term-3/weeks-27-28/README.md) explored relations within six shared places; [Weeks 29–30](../../term-3/weeks-29-30/README.md) fitted one/two events inside a beat. Here A has one short sound or wait per beat and preserves its whole four-beat pattern across rounds while B independently changes. It is a new accompaniment/coordination task, not another pitch/level, gap, subdivision or exact opening–middle–return exercise. “Backing” names a musical role, not rank or a child's identity.

[Integrated Week 31](../../../term-4/week-31-book-sign-paper-screen.md) offers original book/sign/paper-screen forms; a child may choose a paper-book opening or accompaniment. Music does not prove a working screen or a real book rule. [Integrated Week 32](../../../term-4/week-32-an-inventory-we-can-explain.md) explores adding/taking away and clear records; altering a part is a Music choice, not mathematics evidence or a tested physical design. Term placement follows the [year sequence](../../../year-sequence.md), not an official weekly timetable.

The pack supplies **[Page Turn](SUPPLIED-WORK.md)**: an actual original SubjectNest **computer-created teaching model**, with graphic score, honest author-purpose/source card and synthesized candidate sound. Its stated purpose is to model backing repetition with change in another part so teachers/learners can try their own small duos. No named human composer/performer, cultural tradition, community importance or proved effect is invented. The actual supplied score/source may be encountered through exact description or raised cards and a child's response observed; this is a **narrow partial FE01 opportunity**, while broader people/community contexts still need varied appropriate works/sources.

Use [ten daily scripts](LESSONS.md), [seven practical invitations/live route](MATERIALS.md), [30 participation choices](LEARNER-CARDS.md), [20 worked variants](PRACTICE-SWAPS.md), [20 optional free bridges](EXAMPLE-BANK.md), [short prompts](PROMPTS.md), and two fresh [public checks](STUDENT-CHECKS.md) with a separate [educator key/next steps](teacher/KEY-AND-NEXT.md). Eight original illustrated A4 SVG/searchable-PDF pairs include exact [linear/raised/no-sound alternatives](print/TEXT-ALTERNATIVES.md). Three original [candidate audio files](audio/ASSET-INDEX.md) supply the model and isolated parts with complete event/onset/silence transcripts.

**Audio is candidate only, not cleared for children.** Whole-file human listening, intended device and comfortable local volume/room/stop review are held. Any optional live making also needs exact source/material/technique/participant review. No compulsory singing, headphones, object striking, tapping, movement, recording, public solo, family disclosure/possession or purchase. Choices are offered to everyone without diagnosis, stereotype or fixed learner types. A child's directed adult sound is adult performance; actual hearing, maintained beat/independent parts, sound-making, listener meaning and audience receipt require separate accessible observation.

[Exact ACARA/QCAA crosswalk](CURRICULUM-CROSSWALK.md), [rights/source/local authority ledger](SOURCE-AND-RIGHTS.md), [additional authentic-work gate](AUTHENTIC-SOURCE-SLOT.md), [four-role desk walkthrough](RUN-THROUGH.md) and [QA record](QA-RECORD.md) make limits explicit. Authored/computer-checked is **not independently educator-reviewed, child-tested or classroom piloted**, full-standard attainment, cultural authority or universal-access certification.
