Harmonic Highlights
- Frequent ii-V-I progressions to G major (bIIImaj7) firmly establish it as a prominent secondary tonal center.
- Explicit use of parallel major harmony with Emaj7 and ii-V sequences (C#m7-F#m7-B7b9) targeting E major, creating a rich major/minor modal ambiguity.
- Chromatic alterations like F7 (tritone substitution for B7) and D7#5 introduce color and heightened tension.
Improvisation Focus Navigating the intricate major/minor mode mixture, specifically the shifts between E minor, G major, and parallel E major.
Difficulty Rating 5 (Advanced) due to sophisticated modal mixture, frequent secondary dominants, and parallel major/minor shifts requiring agile harmonic interpretation.
