- The extended tonic dominant (Eb7 for eight bars) establishes a static, modal-blues harmonic landscape.
- The C7b9 chord (bVI7) introduces a sudden chromatic tension point, acting as a dominant leading to the V7.
- The specific turnaround from C7b9 to Bb7 (bVI7 to V7) provides a characteristic tension-release leading back to the tonic.
Improvisation Focus: Eb blues scale and Eb Mixolydian over the dominant 7th chords.
Difficulty Rating: 3 (Intermediate). The repetitive harmony is accessible, but navigating the C7b9 requires specific dominant 7th scale choices.
