Harmonic Highlights:
- Frequent tonicizations to Bb major (Cm7-F7-Bbmaj7#11) emphasize a Lydian sound with the #11.
- Altered dominant chords (D7b9, G7b9, C7#9) provide consistent harmonic tension and color.
- Secondary dominant progressions, such as D7b9 leading to Gm7 (V/ii), drive harmonic motion.
Improvisation Focus: Navigating Altered and Lydian scales to precisely voice the harmony’s specific tension and color.
Difficulty Rating: 4 (Advanced) because the frequent altered dominants and Lydian #11 chords demand sophisticated scale application beyond diatonic improvisation.
