Harmonic Highlights

  • Frequent modal interchange, notably incorporating chords from the parallel E minor (Em7, Am7, Dm7) within an E major context.
  • Striking chromaticism, exemplified by the G0 chord, implying diminished structures or outside movement.
  • Abrupt, distant modulations are introduced via remote ii-V sequences like Fm7-Bb7, challenging key center stability.
  • The E7b9 acts as V7 of Am, leading to a modal minor (iv minor) within the broader E major context.

Improvisation Focus Modal Superimposition.

Difficulty Rating 5 (Advanced). The rapid shifts between diatonic, modal interchange, and distant chromatic harmonies demand a high level of harmonic sophistication.
