- Frequent modulations to the relative major (Eb) are common, often via ii-V-I progressions (Fm7-Bb7-Ebmaj7).
- The harmony employs secondary dominants and chromatic bass lines (G7/D, C7/E) to create tension and forward motion.
- A prominent tritone substitution (A7#11) creates a distinctive Lydian Dominant sound before resolving to Ab6.
- A concise backdoor ii-V-I progression (Bbm7-Eb7-Ab7) briefly modulates to the bVI major.
Improvisation Focus: C Harmonic Minor scale.
Difficulty Rating: 4 (Advanced Intermediate). The blend of chromaticism, secondary dominants, and modulations requires solid harmonic awareness and adaptability.
