Harmonic Highlights

  • Repetitive i – iiø7 – V7 progressions establish a grounded F minor foundation before shifting toward the subdominant.
  • Utilization of F7 as a secondary dominant (V/iv) to transition into a ii-V-I-IV sequence in the relative major, Ab.
  • The structure follows a 16-bar minor blues-adjacent form, utilizing a Dbmaj7 (IV in Ab) as a pivot to return to the Gm7b5 (iiø7) turnaround.

Improvisation Focus F Minor Blues scale and F Aeolian, emphasizing the E natural leading tone to resolve the C7 (V7) dominant tension.

Difficulty Rating 2/5 – The predictable harmonic rhythm and reliance on standard minor ii-V-I vocabulary make it highly accessible for intermediate players.
