Why it sounds like that
A♭ blues minor adds the ♭5 (E♭♭) to A♭ minor pentatonic, creating the six-note blues scale. The ♭5 sits between the 4 (D♭) and 5 (E♭) as a passing tone. This scale is a minor pentatonic with one chromatic addition, not a mode of the major scale.
When to use it
A♭ blues minor fits A♭ minor and A♭ 5th chords in blues, rock, and funk. Use it over A♭ minor progressions when the ♭5 adds tension. The scale also works over B major for a bluesy colour.
Which position to practise
Practise Box 1 first. The root sits on string 4, fret 4, and the range covers frets 4–7 for easy access to the ♭5.
