What it does

Rearranges keys into a hexagonal grid so you can see note patterns clearly
Fits over a standard 88-key piano so your existing keyboard gains a new layout
Consistent hexagonal shapes help you spot chords and scales by sight
Made to order in the USA after you place your order
Shaped to sit on top of your keys for a fresh way to view the keyboard

Practice time feels different when your keyboard shows music theory right on the surface. This overlay rearranges your piano keys into a hexagonal isomorphic pattern, so scales, chords, and intervals line up in a way that makes sense to your eyes and hands.

Each hexagon key sits over your existing 88-key piano keyboard, replacing the usual black and white layout with a repeating grid. The pattern stays the same across every octave, so once you learn a shape in one place, you can find it in others.

This is a great pick for players who want to explore music theory in a hands-on way or who like seeing patterns instead of memorizing note names one by one. It rests on top of your keyboard and follows the hexagonal layout across the full run of keys.

Check that your piano has a standard 88-key layout before you order, so the overlay lines up the way you expect.

Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
