Fretly is a browser-based tool for seeing the guitar fretboard — scales, chords, modes, and fingerings — and turning what you see into printable diagrams and shareable suites.
Here's a scale on the neck, right inside this page:
The core pages
- Scales — any scale in any key, in CAGED, 2NPS, 3NPS and more.
- Chords — voicings (triads to 7ths), drop sets, and arpeggios.
- Suites — save diagrams together and share them with students.
- Tools — a metronome and a chromatic tuner.
