Harmonic Highlights:
- The prominent ii-V-i progression
Em7b5, A7b9, Dm7establishes a strong tonicization of the subdominant minor (Dm). - Strategic use of
Bb7as a tritone substitution for A minor’s dominant (E7), providing a sophisticated approach to the tonicAm7. - Frequent, rapid modulations are evident through multiple ii-V progressions, such as
F#m7, B7(to E) andF#m7, B7, Gmaj7(to G). - Chromaticism and reharmonization are introduced by the unusual
Emaj7and various diminished chords likeF07andG07.
Improvisation Focus: Navigating precise arpeggios and chord-scales that align with each rapidly changing harmonic center.
Difficulty Rating: 4 (Advanced). The frequent, non-diatonic modulations and sophisticated reharmonizations demand precise chord-scale application and advanced harmonic understanding.
