Harmonic Highlights

  • The progression centers on standard I-VI-ii-V turnarounds (Fmaj7-D7b13-Gm7-C7), where the VI chord functions as a secondary dominant to drive the motion toward the ii chord.
  • A brief modulation to the mediant (iii) is achieved through a minor ii-V (Bm7b5-E7b9 to Am7), introducing a temporary shift in tonal gravity.
  • The structure utilizes back-cycling dominants (D7 to G7 to C7) following the circle of fifths to create a strong, functional resolution back to the F major tonic.

Improvisation Focus The most important concept is navigating secondary dominants by targeting altered extensions (b9, b13) to highlight the shifting harmonic colors.

Difficulty Rating 2/5. The harmonic rhythm is predictable and the modulations are standard jazz vocabulary, making it an ideal entry point for intermediate study of the Great American Songbook.
