Harmonic Highlights:
- The piece opens with a strong tonicization of Eb major (bIII) through a clear Fm7-Bb7-Ebmaj7 ii-V-I progression.
- Features cascading ii-V progressions that target multiple temporary key centers, notably Am7-D7 leading to G minor and Gm7-C7 to F major.
- Utilizes a characteristic bebop descending chromatic bass line, exemplified by Cm7 - Cm7/Bb - Am7.
- The D7 chord resolving to Fm7 introduces an intriguing non-functional chromatic progression, adding distinct harmonic color.
Improvisation Focus: Application of altered scales over dominant chords.
Difficulty Rating: 5 (Advanced) Explanation: Navigating its rapid harmonic rhythm, frequent modulations, and complex ii-V progressions demands advanced improvisational skills.
