Ten optional 25-minute starts for Days 71–80. This fortnight introduces timbre as a chosen sound-source quality. Children make a readable A/B source key, keep pitch and event positions fixed while changing the planned source, and design an ending contrast. A is our invented pure electronic tone; B adds a third harmonic to the same fundamental. The A circle and B striped square on paper are keys for sound recipes, not claims that an object, voice or instrument will sound a certain way. Children can use local safe sounds only after actually hearing or observing them. This extends Weeks 13–14 pitch contours without teaching another pitch contour: the optional cue files all use the same 330 Hz fundamental at every event.
The integrated Week 15 offers a call/response project. Its two parts may optionally use different source cards, while this Music pack assesses the choice and reading of timbre sources, not another call/answer structure or ten-tile partition. Integrated Week 16 develops a dry design station for a separate capacity test. Our optional safe source/action comparison is a Music observation only; no paper icon, dry model or sound predicts which vessel holds more. Schools can move these sessions for their local Arts timetable. The Term 2 label follows the project's year sequence, not a state-mandated week schedule.
Start with ten timed lessons, six original practice aids, 30 same-target routes, 20 worked domain swaps, 20 optional interest bridges and short prompts. Two fresh public checks U/V have a separate educator key. Six practice and two check sheets have original illustrated A4 SVG/PDF and exact text/tactile routes. Three original short PCM files have event transcripts, a complete no-sound equivalent for the source-planning target, and a human-listening hold before any classroom playback.
The ACARA v9/QCAA Prep crosswalk names exact codes and limits. A child-directed paper score can evidence a musical plan or reading of its key. It cannot prove a child heard timbre, controlled a voice/instrument, played at a comfortable level or reached a real audience. Note actual acoustic perception, source-making and recipient separately. A real maker/context encounter stays in the authentic source slot until locally selected and permitted. No compulsory singing, object striking, device hearing, partner performance, family disclosure or public solo. Offer broad fixed cards, raised circle/square keys, AAC, pointing, a neutral scribe and pass.
