Harmonic Highlights:
- Features an immediate and striking chromatic shift from Cmaj7 to Dbmaj7, introducing non-diatonic color from the outset.
- Employs sequential ii-V-I progressions, establishing temporary key centers like Ab major (Bbm7-Eb7-Abmaj7) and F major (Gm7-C7-Fmaj7).
- Navigates through a sophisticated chain of dominant cycles, including a sudden transition from ii-V of G (Am7-D7) to ii-V of Db (Ebm7-Ab7) before resolving to the tonic.
Improvisation Focus: Mastery of outlining ii-V-I progressions across multiple transient key centers.
Difficulty Rating: 4 (Advanced). The rapid and non-diatonic modulations require quick harmonic recall and a high degree of melodic adaptability.
