Harmonic Highlights
- Prominent bVIImaj7-i minor resolution (
Ebmaj7toFm7) sets an early Dorian/natural minor color. - Frequent use of viiø7/i (
Eø7toFm7) strongly reinforces the F minor tonic. - Successive dominant 7th chords (
Bb7,Eb7) create clear V7-I movement to bVII (Ebmaj7) and bIII (Abmaj7), adding harmonic interest through temporary tonicization.
Improvisation Focus F Dorian scale.
Difficulty Rating 4 (Advanced). The progression requires navigating frequent chord changes, secondary dominants, and temporary modulations within a minor key framework.
