- Harmonic Highlights:
- Prominent use of
iiø-V7-i progressions (Gm7b5-C7#9/b9-Fm7) firmly establish the F minor key center. - Frequent tonicization of
Abmaj7 (bIII), including a clear Bbm7-Eb7-Abmaj7 ii-V-I progression in Ab major. - A notable
Bbm7-Gb7 movement where Gb7 (bII7, tritone substitute for C7) resolves deceptively to Abmaj7, creating chromatic interest.
- Improvisation Focus: F Aeolian/Dorian scale with judicious use of altered dominant scales over C7 chords.
- Difficulty Rating: 3 (Intermediate) – While the core is minor ii-V-i, the modulations to bIII and chromatic dominant resolutions add complexity beyond beginner level.
