Harmonic Highlights:
- Prominent use of
Abm6(bVImin6) resolving toEbmaj7(I), establishing a distinctive minor plagal sound in the tonic key. - A descending chromatic dominant chain (
D7, Db7, C7) leading to theiichord (Fm7), introducing significant tension and reharmonization. - Application of
Gb07(bIII diminished) as a passing chord, generating chromatic voice leading into theiichord (Fm7).
Improvisation Focus: Navigating chromaticism and altered dominant scales over complex chord progressions.
Difficulty Rating: 4 (Intermediate-Advanced) – Requires understanding and applying altered dominant and minor plagal sonorities beyond simple diatonic improvisation.
