Harmonic Highlights

  • Employs “constant structure” slash chords (E/F# to B69, G/A to Dmaj9) to pivot rapidly between distant tonal centers like B and D major.
  • Uses chromatic tritone substitutions, specifically Ab9#11 to Gmaj7, creating smooth, non-diatonic descending bass transitions.
  • Features dense ii-V-I sequences in temporary keys (Gb major, Eb minor), requiring high-speed harmonic navigation within a cyclical structure.
  • Utilizes dominant 9sus4 voicings (V/I) to establish a floating, modal atmosphere that delays traditional tonic resolution.

Improvisation Focus Navigating frequent modal interchange and shifting key centers via smooth voice leading over rapid ii-V cells.

Difficulty Rating 4 โ€” The fast Brazilian tempo and constant modulation between unrelated tonal centers require advanced harmonic visualization and rhythmic agility.
