No borrowed song, melody, voice, recording, First Nations story or language appears here. Real works require [maker/source/permission/context review](AUTHENTIC-SOURCE-SLOT.md); do not fabricate cultural meaning or machine-translate a First Nations language. The A/B electronic recipe is a demonstration, not an instrument identity. Fixed digital sample timing and selected amplitude do not establish perceived equal loudness, classroom safe decibels, accurate ear identification or successful instrument technique. The no-sound route meets the *score reading/revision* goal only. Declining a sound or audience reveals no diagnosis or fixed learning style.
