Harmonic Highlights

  • Utilizes a sophisticated minor blues framework, incorporating heavy altered dominant tensions like C7#9 and G7b9b13 to drive functional resolutions.
  • Features frequent ii-V-i progressions in F minor (Gm7b5 - C7 - Fm7) and secondary dominants (F7b9) targeting the subdominant (Bbm7).
  • Employs the II7 (G7) as a secondary dominant to the V chord (C7), heightening tension before the final resolution to the tonic.
  • Navigates a dense harmonic rhythm where altered extensions require precise voice leading between the iv and i chords.

Improvisation Focus The F Melodic Minor scale and the C Altered scale for navigating the dominant-to-tonic resolutions.

Difficulty Rating 3/5: While the 12-bar minor blues form is accessible, the rapid harmonic rhythm and specific altered dominant requirements demand intermediate-level melodic control.
