No borrowed song, melody, voice, recording, First Nations language, story or cultural motif is used. Do not treat these made-up tones as a substitute for music from any community. A real work requires [local maker/source/permission/context review](AUTHENTIC-SOURCE-SLOT.md). Programmed amplitude, file sample rate and a paper symbol cannot establish safe sound pressure, perceived pitch, comfort or audience response. The no-sound route supports the **structure score** goal only. A child choosing silence or privacy reveals no diagnosis or stable “learning style.”
