About Fretshape
Fretshape is a free, browser-based toolkit for guitarists who want to truly see the fretboard — and improvise with a map in their head instead of a pile of memorized notes.
The idea
Most players learn solos note by note, string by string, and forget them just as fast. Fretshape takes the opposite approach: learn the shapes. Scales on the guitar fall into a small set of visual patterns that repeat all over the neck. Once you can see those patterns — and how chords, triads, and progressions live inside them — a solo stops being a memorization exercise and becomes a place you can navigate.
The tools
- Interactive fretboard. Explore scale shapes across the whole neck, with CAGED positions, triads, and intervals labeled the way you actually use them while playing.
- Progressions. Pick a chord progression and instantly see which scales fit over it — including the relative major/minor relationships that unlock half the fretboard.
- Backing tracks. Practice improvising over tracks in different keys and feels, so the shapes turn into music instead of diagrams.
- Theory, in plain language. Short, direct explanations of the concepts behind the shapes — no conservatory degree required.
- Licks. Short phrases that live inside the shapes, ready to drop into your own solos.
- Tuner and metronome. The everyday essentials, right on the same page.
Who it's for
Fretshape is for beginners who feel lost above the fifth fret, intermediate players who can play other people's solos but freeze when it's time to improvise, and teachers who want a clean visual way to show how the neck is organized. If you think in shapes, this was built for you.

Who made it
Fretshape was created by Carlos Almeida, a guitarist who got tired of memorizing solos note by note and started organizing the fretboard the way he actually thinks about it: in shapes. Questions or suggestions? Visit the Contact page.
