  • Frequent use of #I07 and #II07 as chromatic passing diminished chords, exemplified by C6 - C#07 - Dm6 and Dm6 - D#07 - Em7.
  • The progression employs a strong sequential chromatic movement through these diminished chords, adding harmonic color and momentum.
  • Presence of the iii-VI-V/V-V progression (Em7-A7-D7-G7) creating a robust dominant chain leading back to the tonic.
  • The Eb07 chord functions as a non-diatonic passing diminished, providing chromatic tension before the Dm7.
