Harmonic Highlights

  • The progression utilizes chromatic mediant relationships (Gmaj7 to Ebmaj7), creating the expansive, ethereal harmonic landscape characteristic of Shorter’s “post-bop” vocabulary.
  • The Bb7/F to Ebmaj7 movement provides a smooth descending bass line (G-F-Eb), effectively bridging the G major tonic with the G minor modal palette via its bVI chord.
  • Parallelism in the bridge (E13sus to F13sus) employs non-functional constant structures, shifting the tonal center by a semitone to build tension without a traditional V-I resolution.

Improvisation Focus Modal Interchange (navigating the fluid transitions between G Major and G Minor tonalities).

Difficulty Rating 4/5: The juxtaposition of 3/4 time with non-diatonic root movements and ambiguous “major versus minor” centers requires advanced melodic sensitivity and harmonic control.
