Harmonic Highlights

  • The progression features a prominent IV-iv-I resolution (Bbmaj7 - Bbm7 - Fmaj7), utilizing the minor subdominant to create classic chromatic voice-leading.
  • Secondary dominants act as structural pivots, specifically F7 (V7/IV) and A7 (V7/vi), driving the harmony toward the subdominant and relative minor respectively.
  • The sequence employs a vi-II7-V7-I turnaround (Dm7 - G7 - C7 - Fmaj7), a staple of swing-era functional harmony that reinforces the F major key center.

Improvisation Focus Guide tone targeting, specifically emphasizing the movement from the natural 6th (D) to the flat 6th (Db) to highlight the Bbm7 shift.

Difficulty Rating 2 (Beginner): The piece maintains a clear F major tonal center with standard functional changes and a predictable harmonic rhythm.
