- Employs standard I-iii-vi-ii-V cycles in Bb Major, creating a stable, diatonic foundation typical of the era.
- Features a minor ii-V (Am7b5 to D7b9) to resolve into the relative minor (Gm7), introducing functional chromaticism.
- Uses a Dm7b5 to G7 sequence to tonicize the ii chord (Cm7), utilizing modal interchange to add harmonic weight.
- Includes chromatic movement via Db7 between Dm7 and Cm7, functioning as a tritone substitute for G7 to smooth the transition to the supertonic.
