Harmonic Highlights:
- Frequent exploitation of the Lydian mode, evidenced by
maj7#11chords (e.g., Abmaj7#11, Gbmaj7#11) as tonicizations or color chords. - Rapid, non-diatonic modulations via chromatic mediant relationships (e.g., Abmaj7 to Gbmaj7) and sequential ii-V-I progressions that obscure the key center.
- Sophisticated use of tritone substitutions and chromatic dominant 7th movements (e.g., Db7-G7, Gb7-F7) to create tension and unexpected voice leading.
- Ambiguous resolutions and reharmonizations that challenge traditional functional harmony, keeping the listener guessing about the true key.
Improvisation Focus: Melodic Minor scale and its modes (especially Lydian Dominant and Altered Scale).
Difficulty Rating: 5 (Advanced). The harmonic density, rapid modulations, and extensive use of non-diatonic voicings demand a sophisticated understanding of jazz harmony.
