The G blues scale — G Bb C Db D F — with its intervals, the chords it makes and every position on the guitar neck.

G blues is G minor pentatonic with the b5 added — Db.
G blues scale notes and intervals
G blues has 6 notes. Each is named by its distance from the root, which is the same in every key — learn the numbers once and every blues scale reads the same.
Step pattern from the root: W+H – W – H – H – W+H – W (W is a whole step, two frets; H is a half step, one fret; W+H is three frets).
Scales it shares notes with:
- G minor pentatonic — minor pentatonic — the blues scale without the b5

G blues is played in five box shapes that tile the neck between frets 0 and 14. Each box shares frets with the next, so you change shape without stopping. Position 5 sits lowest.

Chords to play G blues over
G blues is the minor scale with the 2 and the b6 left out and a b5 added — the notes most likely to clash — so it works across the chords of G minor and over the dominant seventh chords of a blues in G. It is not an equally good fit on every one of them: over each chord, aim for that chord’s own notes and let the rest pass.
How to practice the G blues scale
- Start with position 5 at frets 0–4, slowly, until every note lands on the click. The loop keeps the shape and the tempo for you.
- Add five beats a minute each time it feels easy. When straight runs get dull, play the same position in thirds — the pattern that turns a scale into lines.
- See every G blues note across the whole neck on the Fretboard, and find each box again an octave up.
