Harmonic Highlights:
- Features a prominent descending diatonic bass line (Ab - Gb - F - Eb) over the tonic chord, creating a ’line cliché’ effect.
- Employs clear functional ii-V-I progressions (Bbm7-Eb7-Ab) reinforcing the Ab major key center.
- Incorporates an extended dominant chain (C7 - F7 - Bb7) that creates strong harmonic tension and propulsion through a series of secondary dominants.
Improvisation Focus: Navigating Mixolydian scales over the dominant 7th chords.
Difficulty Rating: 3 (Intermediate) - The blend of diatonic and extended dominant harmony requires both scalar fluidity and an understanding of chord-scale relationships beyond simple major/minor.
