Harmonic Highlights

  • Features a chromatic line cliché on the VI chord (Abmaj7 to Abaug), utilizing internal voice leading to create movement over static root harmonies.
  • Employs a VI7 secondary dominant (F7) to prepare a ii-V-I turnaround (Bbm7–Eb7–Ab6) in the submediant key area.
  • The progression exploits the relationship between the C minor tonic and Ab major, alternating between minor-key gravity and major-key swing sophistication.

Improvisation Focus C Minor Blues Scale (incorporating the major 6th for Ab major sections).

Difficulty Rating 3 (Intermediate): Requires navigating chromatic alterations within line clichés and managing the transition between the C minor tonic and the Ab major tonality.
