- Utilizes a 24-bar “Jazz Waltz” structure in 3/4, expanding and sophisticatedly re-harmonizing the standard 12-bar blues form.
- The bVII7 (Ab7) functions as a modal interchange chord, creating a “backdoor” flavor that softens the tonic Bb7.
- Incorporates a chromatic ii-V (Bm7-E7) to approach the IV chord (Eb7), functioning as a tritone-related side-step.
- Employs a IV7 to ivm7 (Eb7 to Ebm7) movement, introducing minor subdominant tension typical of gospel-influenced blues.
Improvisation Focus Bb Blues scale integrated with “side-slipping” melodic cells to navigate the non-diatonic ii-V cycles.
Difficulty Rating 3 (Intermediate). The 3/4 meter and rapid chromatic ii-V shifts require more advanced harmonic navigation and rhythmic pocket than a standard 4/4 blues.
