Harmonic Highlights:
- Features extended dominant 7th chord cycles, notably a descending sequence like Eb7-Ab7-Db7-Gb7, expanding beyond typical blues harmony.
- Employs frequent tritone substitutions and chromatic dominant approaches (e.g., Db7, Gb7, B7, A7) to create tension and chromatic movement.
- Includes a iiø7-V7 progression (Cm7b5-F7) that resolves to the V7 chord (Bb7) of the primary key, intensifying the dominant’s role.
Improvisation Focus: Navigating dominant 7th chord tones and their various alterations.
Difficulty Rating: 4 (Advanced Intermediate) - The extensive use of chromatic dominants, tritone substitutions, and extended cycles requires a sophisticated understanding of harmonic function and scale applications.
