F7b9 -> Bbm7Resolution (Minor)2

Harmonic Highlights:

  • The primary tonic is Fm6, not Fmaj7, consistently establishing a minor modal interchange within the stated F major key center.
  • Dominant use of iiø-V7 progressions (Gm7b5-C7b9 and Cm7b5-F7b9) drives forward motion towards minor resolutions.
  • Features a temporary tonicization of Bbm7 through a Cm7b5-F7b9 (iiø-V7-i in Bb minor), creating a transient shift to the iv minor.

Improvisation Focus: F Dorian scale.

Difficulty Rating: 3 (Intermediate) - The consistent minor tonality and recurrent iiø-V7 movements necessitate proficiency in minor key harmony and common jazz cadences.
