You already know scales.
Fretwalk shows you which ones fit the song in front of you.
Mark your song's chords on a fretboard — no chord names to type, no audio to upload. Fretwalk works out each section's key, checks your progression against a library of 48 scales and modes, and hands you a printable PDF of every one that genuinely fits, with full-neck diagrams for each.
How it works
Mark your chords
Tap the shapes you actually play onto a fretboard grid, section by section — verse, chorus, bridge, whatever you call them. Capo supported.
Fretwalk does the theory
Each section's key center is worked out from real functional harmony, and every scale in the library is tested against the notes your chords actually sound.

A clean, printable PDF: every valid scale per section, three fretboard diagrams each covering the whole neck, ready for the music stand.
Why a flat list, not a "best" scale
Most of us hoard scales — we keep learning new ones without ever knowing which apply to the song we're actually working on. Fretwalk answers that exact moment of "I know scales… now what?"
Every scale in your Fretwalk is a valid path through the song. None of them is the answer. Move between them freely, follow your ear, and let the song tell you which one it wants next.
That's why the output is a flat, unranked list. Pentatonics sit beside bebop scales and altered modes as equals — because over your chords, they are. The theory is rigorous; the choice stays yours.
The fine print, kept short
