These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Der Rosenkavalier
Freud Was Right: It's been widely remarked that the instrumental prelude seems to feature a deliberately awkward climactic moment, when the orchestra (particularly the brass section) reaches the top of a crescendo too far ahead of the rhythm. The subtext becomes more obvious when the curtain goes up and the first scene features Octavian and the Marschallin in bed.
