Harmonic Highlights

  • The composition utilizes a binary structure, shifting from D minor in the A section to D major in the B section.
  • The sequence Gm9 - C7 - Fmaj9 - Bbmaj7 functions as a ii - V - I - IV progression in the relative major (F major).
  • A descending chromatic bass line (Dm7/C - E7b9/B - Em7b5/Bb - A7b9) creates smooth voice leading and tension toward the dominant.
  • Frequent use of secondary dominants and ii - V turnarounds creates a dense, rapidly shifting harmonic rhythm characteristic of Bossa Nova.

Improvisation Focus Navigating parallel major/minor modal interchange and the shift from D Aeolian to D Ionian.

Difficulty Rating 4/5: The complex harmonic rhythm and the requirement to master both major and minor ii - V - I vocabularies within one tune make this an advanced standard.
