Harmonic Highlights
- Frequent use of chromatic passing half-diminished chords (e.g., Eø7, F#ø7) to create sophisticated voice leading and tension.
- Prominent descending chromatic dominant cycle (D7, Db7, C7, F7, Bb7) builds anticipation and facilitates modulatory exploration.
- Incorporation of non-diatonic minor chords and related alterations (Am7b5, Abm6, G7b13) adds rich harmonic color and complexity.
Improvisation Focus Mastery of altered dominant scales and chromatic voice leading over non-diatonic chords.
Difficulty Rating 4 (Advanced). The extensive chromaticism, non-diatonic chords, and complex dominant cycles require a strong grasp of advanced harmonic concepts.
