- The IVmaj7 to iv6 (Ebmaj7-Ebm6) transition utilizes modal interchange, providing a classic subdominant minor resolution to the tonic.
- A VI7-II7-V7 (G7-C7-F7) cycle of dominants drives the harmonic motion, typical of early “hot jazz” and ragtime-influenced structures.
- Stepwise diatonic movement over a tonic pedal (Bb - Cm/Bb - Dm/Bb) creates linear interest while maintaining a strong tonal anchor.
- The bVI (Gb) chord introduces a sudden chromatic shift, serving as a dramatic harmonic pivot back to the tonic Bb major.
