Harmonic Highlights:
- Features a tritone substitution (Db7) for G7 (V/ii), creating a bII7-ii movement (Db7-Cm7) that resolves deceptively.
- Employs a colorful minor plagal sound with Ebm7 resolving to Bbmaj7 (bIVm7-I), derived from the parallel minor.
- Contains a clear secondary ii-V-i progression in G minor (Am7b5-D7b9-Gm7), temporarily modulating to the relative minor.
Improvisation Focus: Focus on altered scales and arpeggios over the numerous dominant 7th chords (e.g., Altered, Lydian Dominant).
Difficulty Rating: 4 (Advanced) The frequent use of altered dominants, tritone substitutions, and a minor plagal cadence demands a sophisticated harmonic understanding.
