A blues scale notes and intervals

A 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.

A blues scale positions on guitar — all 5

A blues is played in five box shapes that tile the neck between frets 0 and 13. Each box shares frets with the next, so you change shape without stopping. Position 4 sits lowest.

Chords to play A blues over

A 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 A minor and over the dominant seventh chords of a blues in A. 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 A blues scale

  1. Start with position 4 at frets 0–4, slowly, until every note lands on the click. The loop keeps the shape and the tempo for you.
  2. 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.
  3. See every A blues note across the whole neck on the Fretboard, and find each box again an octave up.
