Music theory finally makes sense — because you can see it.

For educators

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.

  • Batch-export every diatonic chord in a key in one click
  • Compare multiple scales on one page for side-by-side theory
  • Circle of Fifths for teaching progressions & key relationships

For students

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.

  • Download any scale or chord as a keyboard diagram — take it to your piano
  • Slow the tempo down and hear each note in the scale
  • Save the progressions your teacher gives you and revisit anytime

Made by a musician, for musicians.

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.
