Harmonic Highlights:
- The opening C6 (V6) to F7 (I7) establishes a characteristic dominant-seventh tonic, common in bossa nova.
- Frequent secondary dominant usage, exemplified by D7 (V/Gm) often preceding the Dm7-G7 (ii-V of C) progression.
- Clear ii-V-I resolutions (Gm7-C7-Fmaj7) provide anchor points amidst more chromatic movement.
- Temporary tonicizations, such as Am7-D7-G7 leading towards C major (V of F), subtly expand the harmonic landscape.
Improvisation Focus: Mixolydian scales over dominant 7th chords.
Difficulty Rating: 3 (Intermediate). The abundance of secondary dominants and non-diatonic resolutions requires attentive chord-scale application and voice-leading.
