Harmonic Highlights:

- Prominent ii-V-I progression (Ebm7-Ab7-Dbmaj7) resolves to the IV chord, adding harmonic color.
- Characteristic bVII7 dominant (Gb7) resolves to the tonic (Ab6), introducing a blues-infused backdoor sound.
- Extended sequences of secondary dominants (e.g., F7-Bb7-Eb7) create strong directional motion towards the tonic.
