Harmonic Highlights

  • Employs a recurring i - V6/5 progression (Am6 to E7b9/G#) to establish a dark bossa nova atmosphere through smooth chromatic voice leading.
  • Utilizes a brief tonicization of the IV chord (F6) via a ii-V sequence (Gm7 - C7), introducing a momentary shift to the subdominant area.
  • Features sequential minor ii-V progressions (F#m7b5 - B7b9 and Em7b5 - A7b9) that facilitate rapid movement through related minor keys.
  • The use of Am6 as the tonic chord emphasizes a Melodic Minor tonality, avoiding the instability of a minor seventh.

Improvisation Focus The A Melodic Minor scale and the application of Locrian #2 and Altered scales over minor ii-V-I sequences.

Difficulty Rating 3/5: Navigating the frequent minor ii-V modulations and specific bossa nova extensions requires intermediate harmonic fluency beyond basic minor scales.
