- The prominent
Eb/Db(functioning as Ab7b9) resolving toCm7creates a bVII7 to vi progression, characteristic of Bebop reharmonization. - The
Cm7toB7toBb7sequence features a descending chromatic dominant movement, withB7acting as a temporary dominant or tritone substitute. - The shift from
EbtoEb7thenAb7introduces a brief tonicization of the IV chord (Ab), common in blues-influenced jazz harmony.
