Harmonic Highlights:

  • Frequent application of a V/V-V progression (G7-C7) within F minor, adding chromatic tension.
  • Extensive use of the ii-V-I progression to the iv chord (Cm7-F7-Bbm7), creating a temporary Bbm key center.
  • Strategic deployment of a leading-tone diminished chord (B07 enharmonically Abdim7) resolving to the iv chord (Bbm7).
  • Smooth transitions between F minor and its relative major, Ab, facilitated by the Bbm7-Eb7 (ii-V of Ab) progression.

Improvisation Focus: F Harmonic Minor scale.

Difficulty Rating: 4 (Upper Intermediate). The consistent use of secondary dominants and temporary modulations demands sophisticated harmonic understanding.
