# Overnotes An over*tone* is the note you don't quite notice you're hearing. Above any played note sit fainter, higher ones, and those upper partials are what gives a sound its warmth and character. Strike the same pitch on a violin and a flute and you tell them apart easily, right? Same note, different vibe. Carry that idea into teaching and you have the whole intent of this place: what matters most is rarely the bare fact but the resonance around it, the part that gives an idea its colour and makes it stay. So Over*notes* gathers the things I learn, I teach, I share, written to hold more than the minimum. (Fittingly, "overnotes" is also a real musical term—the extra notes a harmonica player can draw out beyond the standard set. *The notes past the obvious ones.* That will do as a motto.) Everything here is free to read, reuse ([with credit](About%20me)), and argue with. Nothing is final; the notes get revised as my thinking does. ## Finding your way There's no fixed table of contents here, and that's on purpose. Use the *search box* in the left-hand pane and chase whatever you're curious about—a word, a name, a half-formed question. The notes are *linked* to each other, so one good search tends to open onto several more. If you'd like somewhere to push off from, try searching for _music education_, _futures literacy_, _leadership_, _philosophy of education_, _productivity_, or _artificial intelligence_. And if something here helps you, take it; if something looks wrong, tell me.
