Harmonic Highlights:
- Standard ii-V-I progressions (Fm7-Bb7-Ebmaj7) establish and reinforce the Eb major tonic.
- Chromatic dominant approaches, such as D7-Db7 leading to G7, create sophisticated tension.
- Extended dominant cycles (G7-C7b9#11-F7-Bb7) drive the progression through a series of temporary V-I movements.
- A clear modulation to the IV major (Abmaj7) is introduced via a classic ii-V-I progression (Bbm7-Eb7).
Improvisation Focus: Mixolydian and Altered scales are paramount for navigating the numerous dominant seventh chords and their chromatic alterations.
Difficulty Rating: 4 (Advanced Intermediate). The rapid chord changes, extended dominant cycles, and frequent altered dominant chords demand significant harmonic awareness and agility.
