Harmonic Highlights

  • This 12-bar blues utilizes an Am7 - D7 (iii-VI7) progression in bar 8 to create a secondary dominant bridge to the subdominant Gm7.
  • The harmonic rhythm increases in the final four bars with a classic I-VI-ii-V turnaround (F7-D7-Gm7-C7), providing a strong cadential pull for repetitions.
  • The structure adheres to a standard F7 tonic and Bb7 subdominant framework, maintaining a traditional blues tonality throughout the head.

Improvisation Focus The F Minor Blues Scale (F, Ab, Bb, B, C, Eb) used to create rhythmic, riff-based motifs.

Difficulty Rating 1/5: Its slow tempo and predictable 12-bar structure make it the quintessential introductory piece for learning jazz blues vocabulary.
