Harmonic Highlights:

  • Features a prominent “backdoor dominant” progression (Abmaj7 - Db7 - Eb6), utilizing the IV - bVII7 - I movement in Eb major.
  • Includes extended dominant functions, such as Gm7 - C7 - F7 (iii - V/ii - V/V) leading into ii-V-I cycles.
  • Frequent use of diatonic ii-V-I progressions (Fm7 - Bb7 - Eb) establishes a clear, yet dynamic, harmonic foundation.
  • The Db7 (bVII7) chord introduces a distinct bluesy flavor within the otherwise diatonic Eb major context.

Improvisation Focus: Eb Major scale, emphasizing blues language over the bVII7 chord.

Difficulty Rating: 3 (Intermediate). Requires navigating diatonic harmony with a specific focus on the characteristic backdoor dominant progression.
