KEYVISION helps you communicate music theory the way the piano actually looks. Type a scale, pick a chord, hit play — and you get a clean, downloadable keyboard diagram with the exact notes lit up. Perfect for lesson slides, PDF handouts, and daily practice.
Teach theory in half the time
Explaining a scale, mode, or extended chord in text is slow — and it loses beginners. With KEYVISION you drop a live keyboard diagram into any lesson so students see the exact keys they need to play. One click and you have a print-ready PDF for your course slides, worksheets, or handouts. No more sketching on whiteboards or hunting for the right image.
See it. Hear it. Practice it.
Stuck on a scale? Confused about a chord? Type it into KEYVISION — the exact keys light up on a full keyboard, and you can hear it played back at your own tempo. Then download a clean PDF and stick it on your music stand. It's the cheat-sheet you wish you had in your first year of lessons.
From C Major to the diminished-whole-half. Correct enharmonic spellings automatically.
Hear any scale, chord, or full progression. Adjust tempo. Watch the notes light up in time.
One click for every diatonic chord. One-column or two-column layouts. Print-ready.
Colour-coded by diatonic function. Click any wedge to build & play a progression.
No subscription. No monthly fee. One payment and it's yours forever — including every future scale, chord, and feature we add.
KEYVISION was created by Aastha Gupta — because piano teachers deserve better than clip-art keyboard diagrams, and students deserve to actually see what their fingers are supposed to do. Every feature here comes from teaching real students in real lessons.
