Harmonic Highlights:
- Features fluid modulations, often via ii-V-I progressions, establishing temporary tonalities in keys such as Eb major, F minor, G major, and Gb major.
- Includes a striking modulation to G major (Am7b5 D7b9 Gmaj7), the major dominant, providing a distinct bright contrast to the minor tonic.
- Employs both standard minor iiø-V7b9 progressions (e.g., Gm7b5 C7b9) and a prominent chromatic ii-V-I sequence (Abm7 Db7 Gbmaj7).
- Alternates between various dominant qualities, including V7b9 and Bb7alt, adding color and tension.
Improvisation Focus: Targeting chord tones and extensions while navigating rapidly shifting key centers with precise scale choices.
Difficulty Rating: 5 (Advanced) due to the frequent, sometimes remote, modulations and complex chord alterations demanding precise harmonic recall and execution.
