Blues Scale Ear Training
The blues scale adds one magic ingredient to the minor pentatonic — the "blue note." This single chromatic passing tone transforms the scale from clean minor pentatonic into the gritty, soulful sound of the blues.
What is the blues scale?
The blues scale is the minor pentatonic plus a flatted 5th (the "blue note"). In A: A-C-D-D♯-E-G.
That D♯ (or E♭) between D and E creates a chromatic passing tone that gives the blues its characteristic "bending" quality — even when played on a keyboard where you can't physically bend strings.
How to recognize the blues scale
- It sounds like a minor pentatonic but with an extra "crunchy" note in the middle.
- If you hear a scale that sounds minor and has a moment of chromatic tension that immediately resolves, it's likely the blues scale.
- The blues scale has 6 notes vs 5 in the minor pentatonic — listen for that extra step.
The blue note is usually played quickly as a passing tone, not dwelt upon. It creates flavor, not dissonance.
The blues scale in music
The blues scale is foundational to American music:
- Blues: B.B. King, Muddy Waters, Stevie Ray Vaughan.
- Rock: Led Zeppelin, The Rolling Stones, Jimi Hendrix.
- Jazz: Charlie Parker, Miles Davis used blues scales over chord changes.
- Pop/R&B: Ariana Grande, The Weeknd use blues inflections in vocal runs.
