Harmonic Highlights:
- The strong F minor key center is established by frequent i-iv-V7b9-i progressions, notably using C7b9 (Phrygian dominant).
- Brief tonicization of the relative major (Ab6) occurs through a ii-V (Bbm-Eb7b9) preceded by a secondary dominant (F7b9 to Bbm).
- Sophisticated chromatic bass movement (G7b9/F, C7b13/E) provides smooth voice leading into the tonic dominant.
- Harmonic color is added by the bVI major (Dbmaj7) and a ii-V to the dominant (Gm7b5, G7b9).
Improvisation Focus: F Harmonic Minor scale.
Difficulty Rating: 4 (Intermediate-Advanced). It demands a solid grasp of minor key harmony, altered dominant scales, and navigating chromatic voice leading.
