Harmonic Highlights:
- Prominent use of ii-V progressions targeting both the relative major (F) and the subdominant (Gm).
- Features a clear modulation to the dominant major (Amaj7) via a minor ii-V-I (Bm7b5-E7b9), a characteristic minor key turnaround.
- Employs altered dominant chords (D7#9, D7b9, E7b9) to enhance tension and drive towards resolutions.
Improvisation Focus: Chord tone improvisation emphasizing accurate scale choices (Dorian, Mixolydian, Altered) for ii-V progressions and temporary modulations.
Difficulty Rating: 4 (Advanced-Intermediate) - It demands solid navigation of frequent ii-V progressions, altered dominant voicings, and key center shifts.
