- Juxtaposition of the minor tonic (Bbm) with the later appearance of a Bb major quality (Bb6).
- Prominent use of the bVI7 chord (Gb7) functioning as a pre-dominant leading to the tonic.
- Sophisticated chromatic progression via Dm7 - Dbø7 - Eb, demonstrating complex voice leading.
- The Ebm/F (V7sus4b9) chord provides a distinctive minor-infused dominant resolution back to Bbm.
