The fretboard diagram that isn't stuck in one key

Static charts show you A minor pentatonic. GuitarBlots shows you yours — any key, any position, any time.

Without an account

No sign-up, no email. Open it and play.

Any scale or chord, in any key

Twelve keys. Major, natural minor, major and minor pentatonic, blues, Dorian and Mixolydian. Major and minor triads, dominant 7, major 7 and minor 7.

A minor pentatonic, box 1, with note names on each blot

One box, or the whole neck

See a single CAGED box while you learn its shape, combine several to join them up, or take the whole neck at once.

Note names or intervals

Read the shape as letters while you are finding it, then switch to intervals when you want to know why it works.

The same box labelled with intervals instead of note names

Chord tones

See the notes of a chord across the neck, so you can find them inside the scale you are playing.

With an account

Accounts are invite-only while GuitarBlots is in alpha.

Your work is still there when you come back

Save a diagram with a name that will mean something later, reopen it, change it, and save it again without collecting near-identical copies. New accounts start with six worked examples rather than an empty list.

Roots

Everything but the root notes dims, so the shape stops being a pattern and starts having a home.

The same box with only the root notes highlighted

The blue note

Add the flat fifth to the minor pentatonic without switching scale, and see exactly where it sits.

Guide tones, triads, double stops, slide shapes

The notes that carry a chord change, triads on any three adjacent strings, playable double stops, and the shapes you slide into.

The B.B. box

The small shape at the top of the neck that a great deal of blues lead playing comes out of.

The B.B. King box on the top three strings

Every diagram here was drawn by GuitarBlots itself, by the same code that draws them in the app.
