Sound and defining tones
Ab minor blues adds the flat fifth to minor pentatonic: b3 (Cb), b5 (Ebb), and b7 (Gb). The flat fifth is usually treated as a blue-note tension that moves into the fourth, fifth, or another chord tone.

- Play Ab Minor Blues from one Ab root to the next in at least two fretboard positions, saying each note name and scale degree aloud.
- Practice moving through b3 (Cb), b5 (Ebb), and b7 (Gb) chromatically, then vary which note receives the accent or bend.
- Play one chorus of a blues in Ab using only minor pentatonic, then repeat it while adding the flat fifth only as a passing or approach tone.
