Harmonic Highlights

  • Tonic minor line cliché (Gm7-Gm6-Gmb6) employs chromatic internal voice-leading (F-E-Eb-D) over a static G root.
  • G7 (V7/IV) functions as a secondary dominant, smoothly transitioning the G minor tonality toward the Ebmaj7 chorus.
  • A subdominant minor shift (Ebm6) provides a “iv-I” cadence returning to the relative major center of Bb.
  • Frequent use of D7sus to D7b9 (V7sus-V7alt) creates the signature tension-release tension characteristic of bossa-inflected jazz.

Improvisation Focus

G Melodic Minor to navigate the shifting 6th and 7th degrees within the tonic minor cliché.

Difficulty Rating

3/5. While the tempo is usually moderate, the shifting modal centers and chromatic inner voices require sophisticated guide-tone navigation.
