Harmonic Highlights

  • The repetitive oscillation between Fmaj7 and Ebmaj7 (Imaj7–bVIImaj7) utilizes modal interchange, specifically borrowing from the F Mixolydian mode.
  • The transition from Bbmaj7 to Bbm6 establishes a classic IV–iv–I progression, utilizing the minor subdominant for chromatic voice leading (D to Db to C).
  • Use of a secondary dominant (G7 as V/V) creates a strong functional pull toward the ii–V–I turnaround (Gm7–C7–Fmaj7) that anchors the F major tonality.

Improvisation Focus Modal Interchange: Shifting between F Ionian and F Mixolydian to address the bVII (Ebmaj7) color.

Difficulty Rating 2: The harmonic rhythm is predictable and the tempo is typically slow, though the non-diatonic bVIImaj7 requires fundamental knowledge of modal shifts.
