The C# blues scale is the six notes C#, E, F#, G, G# and B. Read as scale degrees from C#, 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 C#, E, F#, G, G# and B sits under it without clashing. On the guitar this is not one shape but overlapping positions: the lowest C# sits at fret 2 on the B string. 5 of the 104 song sheets charted here are in E.

Start here: one C# blues position

The notes inside frets 2 to 6 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.

Numbers 1 to 6 are the playing order, one note at a time. Letters are the other C# blues notes in this position; orange letters are roots.

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 C# minor pentatonic scale with one note added, the flat 5th (G). Slide into it or bend through it, but do not sit on it: the pull back to G# is the whole sound.

Chords that fit the C# 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 C# 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 C#: low E string, fret 9. 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.
  3. Then stop counting. Pick a song in E from the list below and improvise on these notes for two minutes. That is what the scale is for.

C# blues scale: common questions

What notes are in the C# blues scale?
The C# blues scale is C#, E, F#, G, G# and B. Counting from the root C#, the degrees are 1, ♭3, 4, ♭5, 5, ♭7.
What is the formula for the C# blues scale?
The step pattern is m3-W-H-H-m3-W. Read left to right from C#: 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 C# blues scale?
The chords built only from C#, E, F#, G, G# and B are Em, E, Eadd9 and C#m; Em appears 155 times in the library. Shared scale notes can still create tension over a chord, so use its chord tones for stable phrase endings.
How is the C# blues scale related to the C# pentatonic scales?
The C# blues scale is the C# minor pentatonic with the flat 5th (G) added. The pentatonics work the other way: C# major pentatonic takes F# and B# out of C# major, leaving five notes that are hard to play wrong.
What is the easiest fingering for the C# blues scale?
The position above starts on the A string at fret 4 and stays inside frets 2 to 6: C# at fret 4 on the A, then E at fret 2 on the D, then F# at fret 4 on the D, then G at fret 5 on the D, then G# at fret 6 on the D, then B at fret 4 on the G. Everything else on the neck is the same notes repeated in other positions.
How do I practise the C# blues scale?
Play frets 2 to 6 up and back, naming each note. Then locate C# at fret 9 on the low E string. Use the neck diagram to learn that position, rather than copying the same grip across strings. Practise at 60 BPM.
