Harmonic Highlights

  • Rapid modal interchange between F Major and F Minor in the A sections, specifically the transition from Fmaj7 to Fm7.
  • Use of the subV7/V (Db7) to create chromatic tension before resolving to the ii-V (Gm7-C7) of the tonic.
  • A bridge that modulates to the key of Ab Major (the bIII relative to F) via a Bbm7-Eb7-Abmaj7 progression.

Improvisation Focus Navigating parallel major-to-minor shifts (F Ionian to F Dorian/Minor).

Difficulty Rating 3/5: Requires the ability to track tonal shifts between the tonic major and its parallel minor/relative major keys.
