Harmonic Highlights

  • Features a recurring ii-V-I sequence in F Major (Gm7–C7#5–Fmaj7), functioning as a temporary tonicization of the bVII degree within the G minor context.
  • Utilizes chromatic passing diminished chords (F#°7 and G#°7) to create fluid stepwise voice leading between the diatonic minor chords.
  • Employs a subdominant minor cadence (Fm7–Bb7#5–Ebmaj7) in the bridge, effectively transitioning to the flat VI major key area.
  • Relies on altered dominant tensions (A7b9, C7#5) to provide the sophisticated, melancholic harmonic color essential to the Bossa Nova idiom.

Improvisation Focus Navigating the Altered scale and guide-tone connections to highlight the shifting extensions over the ii-V-I progressions.

Difficulty Rating 3/5: The moderate tempo allows for melodic exploration, but the performer must accurately track frequent modulations and chromatic passing harmonies.
