  • Ascending sequence of major chords (G, A, Bmaj7, Cmaj7#11) creates an evolving modal landscape, often featuring Lydian extensions.
  • The Bb13b9 serves as a potent altered dominant, introducing significant chromatic tension and potential for unexpected voice leading.
  • A brief, standard Fm7b9-Bb7 ii-V progression tonicizes Eb major, providing a contrasting tonal area.
  • The piece culminates on a prolonged Emaj9#11 chord, establishing a bright E Lydian sonority which subtly reinterprets the stated E minor key center.

Improvisation Focus: Lydian Mode.

Difficulty Rating: 4 (Advanced). The frequent modal shifts, prominent altered dominants, and the nuanced Lydian resolution demand sophisticated harmonic understanding and scale application.
