- Frequent and rapid modulations through distinct keys such as Eb major, B major, and A major, challenging the soloist to adapt quickly.
- Extensive use of II-V-I sequences (e.g., Fm7 Bb7 Ebmaj7, C#m7 F#7 Bmaj7, Bm7 E7 Amaj7) driving the harmonic rhythm and key changes.
- Chromatic dominant 7ths, such as Ab7 leading to Bb6, add tension and unexpected resolutions, suggesting tritone substitutions or non-functional dominants.
- While in G minor, the progression frequently establishes strong temporary major key centers, diverging significantly from the initial tonic for extended periods.
Improvisation Focus: Chord-scale theory application to navigate rapid modulations.
Difficulty Rating: 5 (Advanced) The constant, rapid key changes and extensive use of II-V-I progressions demand highly developed harmonic awareness and technical proficiency.
