Harmonic Highlights:

  • Shifting ii-V progressions that target multiple tonal centers, moving rapidly between C Major, D Minor, and the tonic F Major.
  • Chromatic side-slipping via the Ebm7-Ab7 to Dm7-G7 sequence, creating temporary tension before resolving back to the home key.
  • Heavy use of dominant 7th chords with altered extensions (b9) to facilitate smooth chromatic voice leading during turnarounds.

Improvisation Focus: Navigating rapid ii-V-I sequences using guide-tone lines and the F Major bebop scale.

Difficulty Rating: 3/5 The frequent modulations and rapid harmonic rhythm require a solid grasp of functional harmony and quick mental transposition.
