Harmonic Highlights
- Utilizes a modified 12-bar blues structure in Ab, characterized by dominant 7th chords that establish a blues-gospel tonality.
- Features a distinctive chromatic “side-slip” in measure 9, using a D7 (bV7) as a tritone-related approach chord leading directly to the Db7 (IV7).
- Replaces the traditional ii-V turnaround with a repetitive IV-I (Db7 to Ab7) plagal movement, reinforcing a static but groovy harmonic foundation.
Improvisation Focus Ab Blues scale integrated with Ab Mixolydian for idiomatic blues phrasing.
Difficulty Rating 2/5; the 12-bar form is highly accessible, though the chromatic D7 in the turnaround requires precise harmonic targeting.
