G blues scale

The G blues scale has 6 notes: G – B♭ – C – D♭ – D – F. It sounds like a minor pentatonic with the “blue note” that gives it its gritty color. It adds the diminished fifth to the minor pentatonic; it's used for blues, rock, jazz and funk solos.

From one note to the next, the scale moves like this: T½ – T – S – S – T½ – T (T = whole step, S = half step, T½ = step and a half). That pattern is the same in every key: once you learn it, you can build the blues scale from any note.

How to practice this scale

  • Play it slowly with a metronome, one note per beat, and only speed up once it sounds even.
  • Sing the note names while you play it: that way you train your ear and your memory at the same time.
  • On guitar, learn it in “boxes”: five positions that repeat along the neck. Start with the one that has the tonic on the 6th string.
  • Improvise over a backing track or a single chord: with these notes almost nothing sounds “wrong”, so it's ideal for losing your fear.
