Harmonic Highlights:
- Prominent use of altered dominant chords (C7b13, C7b5#9) consistently resolving to the F minor tonic.
- Features a secondary dominant (Bb7) and a ii-V progression (Bbm7-Eb7) temporarily hinting at the relative major (Ab).
- The bVI7 chord (Db7) functions as a chromatic dominant preceding the V7, adding a distinct modern harmonic color.
- The occasional Fm/maj7 chord provides a rich melodic minor sound for the tonic.
Improvisation Focus: F melodic minor scale and its modes (especially altered scale for V7 chords).
Difficulty Rating: 4 (Advanced Intermediate). The frequent use of altered dominants and non-diatonic progressions requires a strong grasp of modern harmonic concepts.
