Harmonic Highlights:
- Frequent use of secondary dominants (e.g., D7 leading to Gm7), establishing temporary tonicizations.
- Inclusion of chromatic diminished chords (e.g., Cm7 - C#07 - Dm7), creating tension and smooth voice leading.
- Sustained passages featuring altered dominants (Eb7b9) and tonic Lydian dominant chords (Bb7#11), pushing beyond diatonic harmony.
- Unexpected harmonic shifts, such as the backdoor minor ii-V (Ebm7 - Ab7) resolving to Dm7, adding modern complexity.
Improvisation Focus: Applying chord-scale theory with emphasis on altered dominants, Lydian dominant, and chromatic passing tones.
Difficulty Rating: 5 (Advanced) Rapid chord changes, sophisticated voicings, and numerous altered dominants require a high level of harmonic fluency and technical proficiency.
