Harmonic Highlights:

  • The progression opens with a Cm6, immediately followed by Gm7-C7-Fmaj7, creating an initial modal ambiguity and a swift tonicization of F major, departing from the F minor key center.
  • Features a sequence of descending ii-V-I progressions that rapidly shift through major keys (Fmaj7, Ebmaj7, Dbmaj7), producing a “sheets of sound” effect through chromatic major key movement.
  • The Dm7b5-G7b9 functions as a crucial ii-V leading to C minor, the dominant of the F minor tonic, effectively setting up a return to the implied home key.

Improvisation Focus: Targeting chord tones and accurately outlining the rapid, shifting ii-V-I progressions.

Difficulty Rating: 4 (Advanced) - The quick, sometimes distant key changes and implied modulations require sophisticated harmonic awareness and fluid execution.
