- The #I° diminished chord (B°7) acts as a chromatic passing tone between the Bb6 tonic and the Cm7 supertonic, a hallmark of swing-era part-writing.
- A descending chromatic sequence (Bbmaj7/D – Db°7 – Cm7) utilizes a bIII°7 chord to bridge the inverted tonic to the ii chord.
- Frequent use of altered dominant tensions, specifically the F7#5, provides a more pungent resolution back to the Bb major tonic.
