Harmonic Highlights:
- Striking chromatic dominant descent: E7 (V7/vi) -> Eb7 (Tritone sub for A7) -> D7 (V7/V) provides tension and movement.
- Frequent tonicization of the subdominant (F major) via clear ii-V-I progressions (Gm7-C7-F6).
- Presence of a bluesy I7 chord (C7) within the C major framework, often functioning as V7/IV or a turnaround.
- Clear tonicization of the relative minor (Am) with a ii-V-i progression (Bm7b5-E7-Am).
Improvisation Focus: Mixolydian scales over the numerous dominant 7th chords.
Difficulty Rating: 4 (Intermediate-Advanced). The rapid secondary dominants, tritone substitutions, and temporary modulations demand a sophisticated understanding of harmony.
