- Frequent use of diminished chords (B07, C#07) as chromatic passing harmonies, often leading to a tonic inversion (e.g., C#07 to Bb/D).
- Prominent altered dominant chords (Ab7#11, G7b13, Bb7#5#9, D7b9) providing rich harmonic tension and color.
- Strategic tritone substitution (Ab7#11 for D7) leading to a secondary dominant (G9), preparing a resolution to G minor.
- A clear ii-V-i progression (Am7b5-D7b9-Gm) establishes a temporary modulation to the relative minor key.
Improvisation Focus: Altered Scale application over dominant chords.
Difficulty Rating: 4 (Advanced-Intermediate). The extensive use of altered dominants and chromatic diminished chords demands a sophisticated harmonic understanding.
