Harmonic Highlights
- Establishes D minor via prominent, repeated iiø-V7 (Em7b5-A7b9) resolution.
- Showcases a distinct modulation sequence from Bb major (Cm7-F7-Bbmaj7) to F major (Gm7-C7-Fmaj7).
- Employs sequential minor ii-V progressions (e.g., Bm7b5-E7b9), creating temporary tonicizations.
- A chromatic dominant (Eb7) functions as a pivot, smoothly guiding the progression towards a new key area.
Improvisation Focus Navigating ii-V-I progressions across rapidly shifting key centers.
Difficulty Rating 4 (Advanced). The frequent modulations and sequential dominant cycles demand adept harmonic navigation and quick scale/arpeggio application.
