Harmonic Highlights:
- The Bb7#11 chord introduces a Lydian Dominant sound, creating tension and functioning as a potential tritone substitution before a ii-V or tonicization.
- The progression frequently utilizes ii-V sequences, notably Am7-D7 (V/ii) leading into Gm7-C7 (ii-V of F).
- A significant modulation to Ab major is presented via the Bbm7-Eb7-Abmaj7 ii-V-I, temporarily shifting the tonal center.
- Secondary dominants, such as D7 (V/ii) and A7 (V/iii), are employed to tonicize intermediate chords and add harmonic momentum.
Improvisation Focus: Chord tone outlining and navigating multiple key centers.
Difficulty Rating: 4 (Advanced Intermediate). Requires fluent command of ii-V progressions, altered dominant sounds, and adept navigation through significant modulations to distant keys.
