Harmonic Highlights

  • The progression features an unconventional “delayed resolution,” beginning on the dominant (C6/C7) for several bars before finally landing on the tonic F major.
  • It utilizes a “Cycle of Fifths” movement (VI7–II7–V7–I), specifically using secondary dominants like D7 and G7 to drive harmonic momentum toward the cadence.
  • The structure relies on frequent ii–V cells (Gm7–C7) to reinforce the F major tonal center, typical of the Swing-era “Rhythm Changes” influence.

Improvisation Focus Navigating the VI–II–V–I cycle using smooth guide-tone connections between the 3rds and 7ths of each chord.

Difficulty Rating 2/5 — The harmony is strictly functional and diatonic, though the typically fast “Swing” tempo requires fluid command of standard ii-V-I patterns.
