- Employs a 12-bar blues framework in Bb with a “backdoor” ii-V (Ebm7–Ab7) substitution, providing a chromatic path back to the tonic.
- Features rapid ii-V-I turnarounds and cyclic vi-ii movement (Gm7–Cm7), creating the harmonic density characteristic of high-speed bebop “blowing vehicles.”
- Utilizes the minor subdominant (Ebm7) to introduce modal interchange, momentarily shifting the harmonic color from bright major to parallel minor.
Improvisation Focus Arpeggio-based voice leading with chromatic enclosures.
Difficulty Rating 3/5: While the 12-bar blues structure is fundamental, the typical “tenor battle” tempo requires exceptional technical facility and rhythmic clarity over fast-moving changes.
