The arrangement at the beginning of "Exclusively for Me" is fairly sparse (just a vocal, electric piano, and bass), and in a way, this small number of parts musically represents the exclusivity in the title phrase and the void of the "lonely, empty room."
In reviewing the lyrics, I also noticed that the contrast in the line "The winter's night gives way to a warm summer's day" is emphasized by the duality of opposite elements: winter to summer and night to day.
