- The progression utilizes a “blue” iiø7–V7 (Cm7b5–F7) borrowed from the parallel minor to resolve into the Bb major tonic, creating immediate modal tension.
- The bridge shifts to the dominant key (F major), employing sequential ii–V–I progressions (Gm7–C7–Fmaj7).
- Functional use of the #i°7 (F#°7) serves as a passing chord to the ii (Gm7), facilitating smooth chromatic voice leading during the modulation.
Improvisation Focus
- C Locrian #2 scale over the Cm7b5 to navigate the non-diatonic b5 while maintaining tonal clarity.
Difficulty Rating
3/5: The integration of minor ii–V progressions within a major key and the rapid modulations in the bridge require precise harmonic navigation beyond basic diatonic patterns.
