Tips for Learning the F Blues Scale on Guitar
It is F minor pentatonic plus one note
Take F minor pentatonic (F Ab Bb C Eb) and slip a B between the 4th (Bb) and 5th (C). That single ♭5 — the "blue note" — is the only difference from the pentatonic box.
The blue note is a passing tone
The B♮ sounds tense on its own — use it to pass through, bending or sliding from Bb up to C, rather than landing on it. In motion it gives the scale its vocal cry.
The first box at fret 1
Anchor position 1 at fret 1 with the root F on the low E string — the same shape as F minor pentatonic, with the B one fret below the C on each string. It is a comfortable low-neck box.
A soulful, dramatic key
F minor is one of the most emotional minor keys, and the F blues scale carries that weight. It sits over F minor, F7, and twelve-bar blues in F.
Target F, Ab, and C
Those three notes spell an F minor chord and make phrases sound resolved. Bb, B, and Eb are colour tones — the B blue note is the spiciest, best saved for tension.
About the F Blues Scale
The F blues scale is six notes — F, Ab, Bb, B, C, Eb — the F minor pentatonic scale with one extra note, the ♭5 (B), added between the 4th and 5th. That added tone is the famous "blue note": it creates the tense, vocal, crying sound that defines blues and rock lead guitar. On the fretboard the F blues scale sits in the same five box positions as F minor pentatonic — the first box anchored at fret 1 — with the blue note one fret below the 5th on each string. It works over F minor, F7, and twelve-bar blues progressions in F.

F Blues — note by note
Every blues scale uses the same six-note formula — scale degrees 1, ♭3, 4, ♭5, 5, and ♭7. It is the minor pentatonic with the ♭5 "blue note" added between the 4th and 5th, the chromatic passing tone that gives the blues scale its signature tension and vocal cry.
