Harmonic Highlights

  • Frequent use of upper-structure slash chords (D/C, G/F) creates sophisticated Lydian and Mixolydian textures, shifting the tonal center away from simple diatonicism.
  • Secondary dominant sequences (A7 to Dmaj7) facilitate brief, elegant modulations to the dominant key area.
  • Modal interchange via the Fm6/C provides a poignant minor-plagal (iv-I) resolution, a staple of Brazilian harmonic language.
  • Dominant 7sus chords (G7sus, A7sus) are used to delay resolution, establishing a suspended, “floating” feel typical of Dori Caymmi’s writing.

Improvisation Focus Chord-scale mapping focusing on Lydian and Mixolydian modes to navigate non-diatonic slash chords.

Difficulty Rating 3/5. The piece requires precise navigation of rapid tonal shifts and slash chords while maintaining the relaxed, lyrical phrasing essential to bossa nova.
