Harmonic Highlights:
- Frequent ii-V-I progressions to G minor (Am7b5-D7b13-Gm7) emphasize the relative minor, featuring a b13 extension on the dominant.
- Tonicization of the subdominant Ebmaj7 via a ii-V (Fm7-Bb7) temporarily expands the harmonic landscape beyond the tonic.
- A chromatic dominant (A7#9) leading into a bVII7 (Ab7) creates an unexpected harmonic color and brief departure from diatonicism.
Improvisation Focus: Applying altered dominant scales and arpeggios over V7 chords while accurately tracking temporary tonicizations.
Difficulty Rating: 4 (Advanced Intermediate) The frequent modulations, chromatic dominants, and altered chord extensions demand a strong command of harmonic analysis and corresponding scale choices.
