Harmonic Highlights:
- Employs a V7/V - V7 progression (G7-C7) to lead to the tonic Fm, establishing a strong dominant preparation in the minor key.
- Features frequent iiø7-V7-i cycles (e.g., Cm7b5-F7b9-Bbm7), driving harmonic motion and creating tension-resolution points.
- Regularly tonicizes the relative major (Abmaj7) through ii-V progressions (Bbm7-Eb7), adding a contrasting brighter harmonic color.
- Utilizes altered dominant chords (F7b9, Eb7b9) to enhance chromaticism and resolve strongly.
Improvisation Focus: F Harmonic Minor scale.
Difficulty Rating: 3/5 – Navigating the blend of minor modes, relative major modulations, and frequent ii-V substitutions requires intermediate harmonic understanding.
