How might the audience react in Act 2, Scene 6 of "Romeo and Juliet"?
Well, I think they'd be happy for the couple. It's a short, but beautifully-written scene, and all three of the characters in it express themselves beautifully.
Ah, Juliet, if the measure of thy joy
Be heap'd like mine, and that thy skill be more
To blazon it, then sweeten with thy breath
This neighbour air, and let rich music's tongue
Unfold the imagin'd happiness that both
Receive in either by this dear encounter.
It's a very beautiful, lightly-textured scene: the images are of "gossamer", the wind, the air, music, sweetness, and joy as something which can be heaped up on scales. I'd expect an audience to delight in the beauty of the language - and in the beauty of the moment: Romeo and Juliet are about to be married.
Yet there is one caveat. Act 2 is very early in the play for a marraige - they usually happen at the very end of the play. So perhaps the fact that this marriage happens so early in the play - despite the fact that it is supposed to heal the feud between the Capulets and Montagues - might suggest that something ominous is to come.
