Harmonic Highlights

  • Extended Dominant Tension: The A section sustains a C7b9 (V7) for twelve measures, creating a prolonged Phrygian Dominant soundscape before finally resolving to the tonic Fm.
  • Sequential Dominant Motion: The bridge transitions into a rapid cycle-of-fifths progression (F7–Bb7–Eb7–Ab7), shifting from the modal character of the A section to functional, swing-oriented harmony.
  • Modal Contrast: The harmonic structure juxtaposes the dark, “exotic” Phrygian dominant mode of the A section with the bright, major-flavored dominant cycles of the bridge.

Improvisation Focus The C Phrygian Dominant scale (the 5th mode of F Harmonic Minor).

Difficulty Rating 3/5; while the A section is harmonically static, the performer must maintain melodic interest over twelve bars of a single chord before navigating the bridge’s rapid key shifts.
