Harmonic Highlights:
- The core F minor tonality is firmly established through classic iiø7-V7b9-i progressions, exemplified by Gm7b5-C7b9-Fm7.
- Frequent use of secondary dominants (e.g., F7 leading to Bb7) and chromatic diminished chords (E°7) introduce substantial tension and unexpected voice leading.
- A striking, abrupt modulation to E major occurs via a F#m7-B7-Emaj7 progression, providing a significant and unexpected tonal contrast before returning to the home key.
Improvisation Focus: Navigating temporary modulations and altered dominant chords (like C7b9) requires a strong command of F Harmonic Minor and its related V7 alterations.
Difficulty Rating: 5 (Advanced) – The frequent and abrupt modulations, coupled with extensive secondary dominant and chromatic chord usage, present significant harmonic challenges.
