Harmonic Highlights:
- Establishes C major through frequent ii-V-I progressions (Dm7-G7-Cmaj7).
- Features a clear tonicization of the relative minor with Bm7b5-E7b9-Am7.
- Introduces a striking Eb7#11 chord, functioning as a tritone substitute for A7 (V7/Dm) or bII7, providing significant chromatic tension.
- Employs secondary dominants like D7 (V/V) to add harmonic color and lead to G7.
Improvisation Focus: Navigating targeted altered dominant scales (e.g., Altered, Lydian Dominant) over chords like E7b9 and Eb7#11.
Difficulty Rating: 4 (Advanced Intermediate). The frequent harmonic shifts, combined with the prominent and demanding chromaticism of the Eb7#11, require precise melodic and harmonic understanding.
