Just so you don't think I'm crazy with regards to Juliet's speech we've been discussing, here's part of the text, followed by how it's discussed in The Actor and the Text:
Gallop apace, you firety-footed steeds,
towards Phoebus' lodging! Such a waggoner as Phaeton would whip you to the West
And bring in cloudy night immediately.
Spread thy close curtain, love-performing night,
That runaway's eyes may wink, and Romeo
Leap to these arms untalked of and unseen.
Lovers can see to do their amorous rights
By their own beauties; or, if love be blind,
It best agrees with night. Come, civil night,
Thou sober-suited matron, all in black,
And learn me how to win a losing match,
Played for a pair of stainless maidenhoods.
Hood my unmanned blood, bating in my cheeks,
With thy black mantle till strange love grow bold,
think true love acted simple modestly.
Come, night. Come, Romeo. come, thou day in night;
For thou wilt lie upon the wings of night
Whiter than new snow upon a raven's back.
"The first word breaks the rhythm immediately: the first syllable of 'Gallop' has to be stressed.
This then sets up a kind of gallop in the rhythm of the whole, which is related to the racing of her blood, and the whole speech alternates between being quite violent and calm.
In quite a few other lines the first stress is inverted, thus making the first word remarkable.
This happens notably on 'Hood my unmanned blood' where the stress of the whole line is inverted until the last beat, so that the rhythm is underpinning her sexual arousal, and 'unmanned' becomes very specific (Berry 60-61).
Whether you understand the metrical and linguistic changes in the text to show Juliet's sexuality or simply her anxiety and impatience, the language itself says a lot about her character in that moment-that she wants it to be nighttime sooner, that she's appealing to the night itself to take over the day rather than talking herself into having more patience, etc.
Now consider that Richard Kislan, in his book The Musical, suggests that one should analyze the lyrical content of songs for their poetic value (meter, image, etc.) to understand how musicals are put together, and that this along with the musical qualities of songs reveals important information about character, situation and event. Here's the ensemble version of "Tonight" that happens just before the rumble. Like the opening scene, this is a "musical scene" that gives a lot of information about what's going on between the characters and what is about to happen. It reveals conflict and builds tension. But note Maria's part very closely:
So: what can you tell about Juliet from Shakespeare's text, and what can you tell about Maria from the lyrics and music she performs? Also think about Alberto Sandoval Sanchez's analysis of the character of Maria in terms of stereotypical ideas about Puerto Rican women. Does the music reinforce the conception of her as sweet and virginal as opposed to Anita's fiery Latina? And how does this compare to Shakespeare's illustration of Juliet's character? Are there ways to undermine the stereotypes that emerge in West Side Story in a contemporary interpretation of that musical for the stage? Just a few things to think about ...
