Harmonic Highlights

  • Uses a subdominant minor exchange (Fmaj7 to Fm7) providing a smooth chromatic descent to the mediant Em7.
  • Integrates an Ab7#11 as a tritone substitute for the II7, creating a sophisticated backdoor approach to the G7sus dominant.
  • Transitions into an extended E minor vamp (Em7/B to B7#9), establishing a temporary tonal center on the III chord.
  • Employs suspended dominants (C7sus, G7sus) to soften resolutions, maintaining the open, “folk-like” transparency characteristic of the composition.

Improvisation Focus

The C Major scale remains the primary foundation, transitioning to E Harmonic Minor to navigate the B7#9 vamps.

Difficulty Rating

3/5: The piece requires navigating standard diatonic changes alongside sudden modal shifts and non-functional dominant substitutions.
