Harmonic Highlights:

  • Extensive use of the ii-V-I chain (Am7-D7-Gm7-C7) in cyclic motion, creating extended dominant harmony.
  • Chromatic passing motion with the B07 chord, injecting tension before returning to F major.
  • The characteristic bII7 (Db7) tritone substitution for the G7/C7 dominant function, providing a strong Monk-esque resolution to F6.
  • Interplay of diatonic harmony with blues-inflected dominant chords (Bb7).

Improvisation Focus: Navigating altered dominant scales and arpeggios, especially over the D7, G7, and Db7 chords.

Difficulty Rating: 4 (Advanced Intermediate). The frequent chromaticism and tritone substitution require a sophisticated harmonic understanding and nimble melodic execution.
