Harmonic Highlights

  • Employs a chromatic passing diminished chord (Abยฐ7) to bridge the tonic F major to the ii-V progression (Gm7-C7).
  • Features a sophisticated descending dominant sequence (F7โ€“Eb7โ€“D7) that creates a bluesy, linear transition toward the supertonic.
  • Utilizes back-to-back ii-V cells (Bbm7โ€“Eb7 to Am7โ€“D7), effectively incorporating the subdominant minor (iv) and secondary dominants to add harmonic depth.

Improvisation Focus Targeting chord tones (specifically 3rds and 7ths) to navigate the rapid succession of secondary dominants and ii-V turnarounds.

Difficulty Rating 3/5: While the F major tonal center is clear, the frequent use of secondary dominants and minor-iv substitutions requires an intermediate understanding of functional harmony and voice leading.
