  • Prominent use of the parallel minor tonic (Ebm7) following the home Ebmaj7, introducing a melancholic tension.
  • A clear ii-V-I progression in the dominant key (Cm7-F7-Bbmaj7) before Bb7 functions as V7 of Eb.
  • Striking chromatic modulation to B major (B-F#7), presenting a sophisticated reharmonization or chromatic mediant relationship, demanding agile navigation.
  • Eb7/G functions as V7/IV, briefly leading to Abmaj7 and demonstrating a common secondary dominant usage.

Improvisation Focus: Chord-scale mastery across abrupt key changes and sophisticated chromaticism.

Difficulty Rating: 5 (Advanced) due to the abrupt chromatic modulations, particularly the B major section, requiring highly flexible harmonic understanding.
