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.
