  • The opening sequence employs altered dominants (E7alt, A7alt, F#7alt) preceding non-diatonic major chords, creating a series of ambiguous chromatic shifts rather than clear V-I resolutions.
  • Frequent use of altered dominant chords (e.g., B7alt, Eb7alt, Ab7alt) provides rich harmonic tension, often resolving deceptively or to distant major keys.
  • Rapid modal shifts are evident, particularly the B7#11 (V of E minor) leading to Bmaj7 (V of E major), indicating an excursion into the parallel major, reinforced by Emaj7 and subsequent Ab7alt.

Improvisation Focus: Altered Scale.

Difficulty Rating: 5 (Advanced) due to its rapid, complex harmonic rhythm and extensive use of non-functional altered dominants and distant modulations.
