Harmonic Highlights:

  • Frequent Imaj7 - I7 - IVmaj7 progression, where I7 (Eb7) functions as a secondary dominant (V7/IV) leading to Abmaj7.
  • Prominent use of bVII7 (Db7) as a backdoor dominant, smoothly resolving to the tonic Ebmaj7.
  • Classic iii-VI-ii-V (Gm7-C7-Fm7-Bb7) turnaround reinforcing functional harmony in Eb major.

Improvisation Focus: Precise application of chord-scale theory to non-diatonic dominant chords.

Difficulty Rating: 3 (Intermediate). It introduces common jazz dominant extensions beyond simple diatonic harmony, requiring specific scale choices.
