Guitar Scale Finder

Find any guitar scale. Search, tap the notes you know, or play a song, and see every scale that fits. All 1,870 guitar scales in your pocket.

MAGIC LISTEN
Play a song from a speaker, or a riff on your guitar. Magic Listen hears the notes, works out the key and shows you the scales that fit, so you know what to play.

FILTER BY THE NOTES YOU KNOW
Know a few notes but not the scale? Tap them in and the list narrows to the scales that contain every one. Pick a root and a scale type to narrow it further.

HEAR EVERY SCALE, ONE NOTE AT A TIME
Tap play next to any scale and hear it on a clean electric guitar. Tap any note or chord to hear it on its own.

VISUALISE ON THE FRETBOARD
The whole neck, open strings to the 24th fret, in note names or degrees (1, b3, 5...). Turn your iPhone sideways for a full-screen neck.

GUITAR CHORDS THAT FIT YOUR SCALE
Every scale shows the chords built from it, with Roman numerals and every position to play them. On the full-screen neck, pick chords to light up their notes and grey out the rest.

1,870 SCALES
Major, minor and the pentatonics. The modes. Harmonic and melodic minor, blues, bebop, Hirajoshi, Hungarian minor and more, in every key. Bookmark the ones you come back to.

Built by guitarists, for guitarists. We have over 20 years experience playing guitar, and we're dedicated to taking care of the theory so you can concentrate on rocking out.
