Harmonic Highlights

  • Transitions from a melancholic B minor foundation into a brighter parallel B major section, creating a distinct emotional shift typical of bossa nova.
  • Features a sophisticated chromatic modulation to Eb minor via a ii-V (Fm7b5 - Bb7b9), pulling the listener into a distant harmonic landscape.
  • Employs a ii-V-I sequence in the relative major (Em7 - A7 - Dmaj7) to provide temporary tonal stability before returning to the tonic minor.
  • Utilizes dominant 7th chords with altered extensions (F#7b9, Bb7b9) to intensify the resolution within the minor-key turnarounds.

Improvisation Focus Mastering modal interchange between B Aeolian and B Ionian while navigating the altered dominant tones of the V7b9 chords.

Difficulty Rating 4: The rapid modulations to distant keys like Eb minor and the constant shifting between parallel major/minor require advanced harmonic awareness and fluid scale substitutions.
