Harmonic Highlights:
- The B7sus-B7 movement between C6 chords serves as a non-functional chromatic passing dominant, adding tension and subtle re-coloring to the tonic.
- Frequent use of modal interchange, notably the Dm7 to Fm6 progression, creates a melancholic, minor plagal cadence characteristic of Jobim.
- Altered dominant chords like A7b13 and G7#5 provide rich harmonic color and anticipation, leading to both standard ii-V-I patterns and deceptive V-IV resolutions.
Improvisation Focus: Navigating altered dominant scales and modal mixture against an underlying C major tonality.
Difficulty Rating: 4 (Advanced Intermediate) – Requires proficiency in applying various altered scales and understanding non-diatonic harmonic functions within a bossa nova rhythmic framework.
