Harmonic Highlights:
- Prominent use of chromatic passing diminished chords (C#07 to Dm7, Eb07 to Em7) creating smooth voice leading and tension.
- Extensive application of secondary dominants and dominant cycles (A7-D7-G7) driving the progression with strong V-I motion.
- Incorporation of the bVII7#11 chord (Bb7#11) introduces Lydian dominant sound, often functioning as a tritone substitution or modal interchange.
- Features a sophisticated turnaround involving a ii-iii-IV7-bVII7#11 progression, expanding beyond simple diatonic harmony.
Improvisation Focus: Mixolydian scale and its alterations (Lydian Dominant, Altered Scale) are essential for navigating the dominant-heavy and chromatically rich harmony.
Difficulty Rating: 4 (Advanced Intermediate) The frequent modulations, extended dominant chains, and chromatic passing chords demand a solid grasp of jazz harmony and agility.
