Harmonic Highlights:

  • Prominent use of the bVI7 (Db7) functioning as a non-functional dominant resolving to i minor (Fm7) or preceding IVmaj7 (Bbmaj7), characteristic of minor blues or modal interchange.
  • The iiø-V7-i progression (Gm7b5 - C7#9 - Fm7) firmly establishes F minor, with the C7#9 providing an altered dominant sound.
  • The progression Db7 to Bbmaj7 creates a distinctive, non-diatonic harmonic shift from the bVI7 to the IVmaj7 in F minor.

Improvisation Focus: Integrating F minor tonalities (Dorian, Harmonic Minor) with altered scales over V7 and bVI7 chords.

Difficulty Rating: 4 (Advanced Intermediate). The combination of non-functional bVI7 and altered V7 requires adept harmonic navigation and scale selection.
