Guitar scale
F blues scale
The F blues scale is the minor pentatonic plus the blue note (♭5), one extra semitone carrying all the tension and release of the blues. Best for blues, rock and country lead lines.

The F blues scale is the six notes F, Ab, Bb, Cb, C and Eb. Read as scale degrees from F, that is 1, ♭3, 4, ♭5, 5, ♭7. Every note is a fixed distance from the one before it: m3-W-H-H-m3-W, where W is a whole step (2 frets) and H is a half step (1 fret), and m3 is three frets. That pattern is the whole scale. Move it so the root lands on a different note and you are playing that key's blues scale. Having only six notes, it fits a narrow set of chords: any triad built entirely from F, Ab, Bb, Cb, C and Eb sits under it without clashing. On the guitar this is not one shape but overlapping positions: the lowest F sits at fret 1 on the low E string. 5 of the 104 song sheets charted here are in Ab.
Start here: one F blues position
The notes inside frets 1 to 5 sit in the highlighted box above. The diagram below isolates that position and numbers the run to play. Learn this box first; other positions contain the same scale notes with different fingerings.
Play the box in this order
F 1 → Ab ♭3 → Bb 4 → Cb ♭5 → C 5 → Eb ♭7
Plays exactly the run numbered above, one note at a time.

W whole step (2 frets), H half step (1 fret), m3 minor 3rd (3 frets). The same pattern from any other root gives that key's blues scale.
This scale is the F minor pentatonic scale with one note added, the flat 5th (Cb). Slide into it or bend through it, but do not sit on it: the pull back to C is the whole sound.
Chords that fit the F blues scale
A chord fits this scale when all of its notes are already in the scale, which is a test you can run yourself rather than a style guide. Ordered by real use in the library.
How to practise the F blues scale
- Frets 1 to 5, slowly. The position above, up and back, naming every note out loud. Naming is what turns a shape into a scale.
- Then find the next F: B string, fret 6. Use the full neck diagram to find the scale notes around that root. Play root to root at 60 BPM, one note per beat; fingerings change when you move to a different string set.
- Then stop counting. Pick a song in Ab from the list below and improvise on these notes for two minutes. That is what the scale is for.
