Harmonic Highlights

  • Employs an expanded 16-bar blues structure rather than the traditional 12-bar format, lengthening the tonic and turnaround sections.
  • The $F7^{#9}$ tonic utilizes the “split third” (G#/Ab) to create a gritty, gospel-funk tension between major and minor tonalities.
  • Features a distinctive V-IV (C9 to Bb9) oscillating cadence that repeats three times, providing a rhythmic, call-and-response harmonic foundation.
  • Incorporates $Ab^{13}$ as a bIII dominant substitution, serving as a chromatic neighbor chord to lead back to the tonic.

Improvisation Focus F Minor Pentatonic / F Blues Scale.

Difficulty Rating 2/5: The repetitive 16-bar form and consistent dominant harmony allow beginners to solo effectively using a single blues scale.
