Harmonic Highlights

  • Standard 12-bar blues in F utilizing a ii-V (Cm7-F7) in bar 4 to tonicize the IV chord (Bb7).
  • Integration of a #iv diminished chord (B°7) in bar 6, functioning as a chromatic passing tone between the IV and the tonic.
  • Utilization of a iii-VI-ii-V turnaround (Am7-D7-Gm7-C7) in the final four bars, replacing the traditional V-IV blues ending with cycle-of-fourths functional harmony.

Improvisation Focus F Blues scale combined with Mixolydian guide-tone targeting to emphasize the shifting dominant 7th qualities.

Difficulty Rating 2/5: It is a foundational jazz blues that demands mastery of standard ii-V-I patterns and swing phrasing at varying tempos.
