- The progression frequently cycles around the bVI chord (Ab), employing Abmaj7, Ab7, Ab6, and a distinctive Abaug chord to create prolonged harmonic interest.
- The repeated Abaug (Ab-C-E) introduces a prominent chromatic tension and color, functioning as an altered bVI harmony or a passing dominant quality.
- A clear ii-V-I progression (Bbm7-Eb7-Ab6) strongly tonicizes the Ab major sound, establishing it as a significant temporary key area within the C minor context.
Improvisation Focus: Navigating the Ab major sonority and its specific chromatic extensions, especially over the Abaug chord.
Difficulty Rating: 3 (Intermediate). While featuring common ii-V-I progressions, the prominent and repeated use of the Abaug chord introduces chromatic complexity.
