Harmonic Highlights

  • Secondary ii-V (Gm7-C7) targeting IV (F6) creates a brief tonicization that expands the C major landscape.
  • Modal interchange via the minor subdominant (Fm6) provides a smooth chromatic transition into the standard iii-VI-ii-V turnaround.
  • The bridge utilizes a sudden shift to Abmaj7 (bVI), demanding a quick adjustment to a distant tonal center before returning to the home key.
  • Consistent use of secondary dominants (A7, C7) requires precise voice leading of the 3rd and 7th to navigate the shifting tonalities effectively.

Improvisation Focus Chord-tone targeting with a focus on highlighting the “blue” flat-sixth interval over the Fm6 and the chromatic alterations of the secondary dominants.

Difficulty Rating 2/5 โ€” The progression follows logical functional paths and standard jazz tropes, making it highly accessible for intermediate players.
