Ravel: IV. The Conversation of Beauty and the Beast

"When I think of your good heart, you do not seem so ugly." "Oh, I should say so! I have a good heart, but I am a monster." "There are many men who are more monstrous than you." "If I were witty I would pay you a great compliment to thank you, but I am only a beast."

"Beauty, would you like to be my wife?" "No, Beast!"

"I die happy because I have the pleasure of seeing you once again." "No, my dear Beast, you shall  not die. You shall live to become my husband." ... The Beast had disappeared, and she beheld at her feet a prince more handsom than Amor, who was thanking her for having lifted his spell.

this is the movement that taps into a story we all know. from ravel's description we can easily match up which parts of this conversation map to his quotes and characters. the lovely introductory melody represents the belle, and at 1:16 the low chromatic melody represents the beast (this is a contrabassoon in the orchestral version). clearly the first climax right after this around 2:00 is meant to be the first rejection.
i think in the original fairy tale the beast begins to die here of heartbreak (not like in disney with the angry mob and battering ram). i'm not sure i agree with the cartoon's interpretation, given the content association of the first climax (which is more or less the same, but less intense). i think that perhaps the second climax at 2:50 is meant to be when beauty realizes the beast is dying - and then realizes her affection for him.

the transformative moment after that is given to a violin solo with these really difficult harmonics, in the orchestral version. a cello enters afterwards with a much higher version of the beast theme - perhaps meant to be the beast after his transformation.
