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 (
B07enharmonically 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.
