- The Bb°7 acts as a bIII°7 chromatic passing chord, providing a smooth transitional link between the Vmaj7 (Dmaj7) and the iim7 (Am7).
- Jobim employs modal mixture with the Gm6 chord, momentarily shifting the G major tonality into a G tonic minor (Aeolian) coloration.
- The bridge utilizes descending ii-V progressions to modulate through C major and F major, using slash chords like Gm7/Bb to create a stepwise, melodic bass line.
Improvisation Focus Voice Leading: Target the chromatic alterations (specifically the Eb/Bb in Bb°7 and Bb/Eb in Gm6) to bridge the gaps between diatonic centers.
Difficulty Rating 3/5: While the tempo is typically accessible, the non-functional chromaticism and frequent modulations in the bridge require an intermediate understanding of modal interchange.
