Harmonic Highlights:
- Prominent use of the bVII7 chord (Db7) which resolves chromatically rather than in a direct “backdoor” fashion.
- Intricate dominant sequence (C9-Gb9) functioning as a double leading-tone approach to the F9 (II chord).
- Frequent deployment of rich dominant 9th and 13th extensions (C9, Gb9, F9, Bb13) throughout the progression.
- Seamless integration of standard diatonic turnarounds (III-VI-II-V) with complex chromatic dominant substitutions.
Improvisation Focus: Navigating chromatic dominant alterations and tritone substitutions.
Difficulty Rating: 4 (Intermediate-Advanced). The intricate chromatic dominant movements and substitutions require a solid grasp of advanced harmonic concepts.
