Harmonic Highlights:

  • Utilizes a ii-V-i progression in the relative minor (F#m7-B7b13-Em7) for a sophisticated dominant approach to the iii chord.
  • Features a significant modulation to bVI major (Abmaj7) and its related ii-V (Bbm7-Eb7), introducing distant harmonic color.
  • Employs extended cycle-of-fifths progressions like Em7-A7-Dm7-G7-Cmaj7, demonstrating intricate functional harmony.
  • Incorporates a diminished chord (E07) resolving to the minor iv (Fm7), adding chromaticism and temporary minor key flavor.

Improvisation Focus: Application of chord-scale theory to navigate complex ii-V-I progressions, altered dominants, and temporary modulations.

Difficulty Rating: 4 (Advanced Intermediate). The frequent use of non-diatonic chords, altered dominants, and a full modulation to bVI major demands a deep harmonic understanding.
