Harmonic Highlights

  • Chromatic passing motion via the #io7 (G#dim7) provides a smooth bridge between the Imaj7 (Gmaj7) and the iim7 (Am7).
  • Utilization of the IVmaj7 to ivm7 (Cmaj7 to Cm7) transition incorporates modal interchange, introducing the emotive b6 (Eb) from the parallel minor.
  • The use of a II7 (A7) secondary dominant functions as a “V of V,” heightening the tension before the final ii-V-I resolution.

Improvisation Focus Voice leading through the IV-iv-I progression, specifically highlighting the movement from E to Eb to D.

Difficulty Rating 2/5 โ€” The progression relies on standard diatonic functions and common jazz cliches, making it highly accessible for those familiar with basic functional harmony.
