Harmonic Highlights:
- Establishes Eb major with conventional ii-V-I progressions (Fm7b5-Bb7b9-Ebmaj7).
- Features a transient modulation to G minor (iii minor) via Am7b5-D7b9-Gm7.
- Contains a striking, direct modulation to Gb major (bII) through a ii-V-I progression (Abm7-Db7-Gbmaj7), a common Berlin harmonic characteristic.
Improvisation Focus: Navigating transient modulations and outlining shifting key centers.
Difficulty Rating: 5 (Advanced). The rapid and remote modulations, particularly to Gb major, require a deep understanding of harmonic function and sophisticated melodic navigation.
