Harmonic Highlights:
- The repeated Em7b5 - A7b13 progression establishes a strong iiø7-V7b13 resolution to D minor, indicating a significant temporary tonicization a whole step below the E minor key.
- Cmaj7 functions as a bVImaj7 in E minor, providing a distinct modal interchange color and setting up chromatic interest.
- B7b9 clearly defines the V7b9 of E minor, yet its resolution is immediately followed by a new ii-V sequence, creating continuous harmonic drive.
Improvisation Focus: Navigating altered dominant scales and their resolutions, particularly over B7b9 and A7b13.
Difficulty Rating: 4 (Advanced). The frequent shifts between E minor and D minor tonicizations, coupled with complex altered dominant functions, requires sophisticated harmonic understanding.
