Harmonic Highlights

  • Sequential ii-V-I progressions facilitate smooth modulations between G major and C major, defining the primary harmonic structure.
  • The inclusion of C7#11 functions as a Lydian Dominant substitute, providing a sophisticated bridge between the G major and C major tonal centers.
  • Use of the F7 chord acts as a “backdoor” bVII7 dominant, offering a non-diatonic chromatic resolution back toward the tonic Gmaj7.
  • The Em7-A7-Am7-D7 chain utilizes secondary dominants (VI7 to ii) to create a circular turnaround that maintains forward rhythmic momentum.

Improvisation Focus Navigating modulating ii-V-I cells using major scale and Mixobop scales.

Difficulty Rating 2/5. The progression relies on standard jazz cadences and predictable modulations, making it an ideal study for foundational functional harmony.
