Harmonic Highlights:
- Extensive use of the bIII major (Dbmaj7) and ii-V-I progressions to it (Ebm7-Ab7-Dbmaj7), creating constant interplay between Bb minor and its relative major.
- Striking chromatic dominant movements, such as A7 resolving to Dbmaj7, introduce unexpected tension and release, moving beyond diatonic functions.
- The anchor iiø7-V7-i (Cm7b5-F7b9-Bbm) strongly grounds the progression in Bb minor, providing a clear tonic resolution amidst modulations.
Improvisation Focus: Bb Harmonic Minor scale and its related modes.
Difficulty Rating: 5 (Advanced). Requires navigating complex chromaticism, rapid modulations between relative major/minor, and sophisticated dominant alterations beyond typical diatonic functions.
