The F# blues scale is the six notes F#, A, B, C, C# and E. 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#, A, B, C, C# and E sits under it without clashing. On the guitar this is not one shape but overlapping positions: the lowest F# sits at fret 2 on the low E string. 6 of the 80 song sheets charted here are in A.

Start here: one F# blues position

Every note of the scale inside frets 2 to 6 sits in the box highlighted on the full neck above. The diagram below is that box on its own, numbered in the order to play it. Learn this one box first; the rest of the neck is the same shape repeated.

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 (C). 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

  1. Frets 2 to 6, slowly. The position above, up and back, naming every note out loud. Naming is what turns a shape into a scale.
  2. Then find the next F#: B string, fret 7. Build the same shape from there and play root to root at 60 BPM, one note per beat.
  3. Then stop counting. Pick a song in A from the list below and improvise on these notes for two minutes. That is what the scale is for.

F# blues scale: common questions

What notes are in the F# blues scale?
The F# blues scale is F#, A, B, C, C# and E. Counting from the root F#, the degrees are 1, ♭3, 4, ♭5, 5, ♭7.
What is the formula for the F# blues scale?
The step pattern is m3-W-H-H-m3-W. Read left to right from F#: minor 3rd (3 frets), then whole step (2 frets), then half step (1 fret), then half step (1 fret), then minor 3rd (3 frets), then whole step (2 frets). Apply the same pattern from any other note and you get that note's blues scale.
What chords work with the F# blues scale?
Any chord built only from these notes: F#, A, B, C, C# and E. The chords that fit are A, Am, F#m and Asus2, and A is the one this site's library uses most, 120 times. Every note of the scale is a safe landing note over any of them.
How is the F# blues scale related to the F# pentatonic scales?
The F# blues scale is the F# minor pentatonic with the flat 5th (C) added. The pentatonics work the other way: F# major pentatonic takes B and E# out of F# major, leaving five notes that are hard to play wrong.
What is the easiest fingering for the F# blues scale?
The position above starts on the low E string at fret 2 and stays inside frets 2 to 6: F# at fret 2 on the low E, then A at fret 5 on the low E, then B at fret 2 on the A, then C at fret 3 on the A, then C# at fret 4 on the A, then E at fret 2 on the D. Everything else on the neck is the same notes repeated in other positions.
How do I practise the F# blues scale?
Play the position in frets 2 to 6 up and back, naming every note out loud. When the shape is automatic, build the same shape from the next F# up the neck, at fret 7 on the B string, and only then add a metronome at 60 BPM.
