Harmonic Highlights:
- Extended vamping on bVII13sus (Bb13sus) and bVI13sus (Ab13sus) chords, creating a sustained modal, suspended dominant feel before the primary key resolution.
- The whole-step descent from Bb13sus to Ab13sus suggests a non-functional or side-slipping harmonic movement characteristic of modern jazz vamps.
- A clear functional minor iiø7-V7b9 sequence (Gm7b5-C7b9) strongly establishes and resolves to the F minor tonic.
- The piece demonstrates a dynamic contrast between prolonged static suspended dominant harmony and the tension-release of a traditional minor cadence.
Improvisation Focus: F Harmonic Minor for defining the tonic and the critical V7b9 resolution.
Difficulty Rating: 4 (Advanced Intermediate) Requires navigating extended modal vamps on suspended dominants transitioning into a clear minor ii-V-i cadence, demanding sophisticated harmonic and rhythmic understanding.
