  • Frequent deployment of fully diminished chords as leading-tone or passing functions (e.g., G#07 to Am7, Bb07 preceding Bm7b5).
  • Utilizes the characteristic minor key tonic progression Am - Am/maj7 - Am7, showcasing the descending A melodic minor.
  • Features a clear ii-V-I modulation to the dominant major (Emaj7) via C#m7b5 - F#m7 - B9, immediately transitioning to its minor counterpart (Em).
  • Incorporates advanced substitutions, such as F13 (tritone sub for B7) resolving to the dominant minor (Em6).

Improvisation Focus: Navigating sophisticated modulations and applying appropriate melodic minor and altered dominant scales.

Difficulty Rating: 5 (Advanced) - The rapid and complex chord changes, frequent modulations, and use of advanced harmonic devices demand a high level of harmonic understanding and technical proficiency.
