Poetry=making words fun to say?

In "Jerusalem" (http://www.youtube.com/watch?v=D0pBXHugmLM), Dan Bern ends almost every line by strongly emphasizing one of the final syllables: 

...I said "Oh yes VERy much

But I think my TIMing's wrong"
They said "Time is RELative
Or did you misread EINstein"

I said "Do you really MEAN it?"

They said "What do you think we CAME here for?

For our goddamn HEALTH or something?"

Do these particular syllables--VER, TIM, REL, EIN, MEAN, CAME, HEALTH--have any special significance? Not really. That's just where Dan Bern decided to lay emphasis in order to create a catchy, captivating rhythm or beat. What's interesting, then--and in this case what's funny--is seeing how certain words change or seem different when they're placed in this kind of rhythm or meter. Or put it this way: "MEAN," "CAME," "HEALTH" are kind of boring words, not all that fun to say. But when Dan Bern says them in this song, they're a lot of fun to say or hear: there's something satisfying about putting this hard edge on such simple, everyday words: What do you think we CAME here for? For our goddamn HEALTH or something? The "C" in that "came" is sharp as a knife. This is what poetry does: it makes words interesting and fun to say/hear. "Natives of poverty, children of malheur, / The gaiety of language is our seigneur," says Wallace Stevens. So if "An Old Man's Winter's Night" is full of sadness and despair ("malheur"), it's also "fun" to read because it's full of "the gaiety of language."

As you re-read Frost for Thursday, try to catch some of the fun in his special way of saying things. "The Cow in Apple Time" is about a cow who jumps the pasture fence and nibbles at all the apples scattered on the surrounding fields. Why write/read a poem about something so unimportant and mundane? Maybe just to have the chance to speak/hear such choppy, ominously rhyming statements as these: 

She leaves them bitten when she has to fly.

She bellows on a knoll against the sky.

Her udder shrivels and the milk goes dry.

I don't know about you, but sometimes I get sick of reading newspapers and blogs and advertisements: sick of reading things that someone wrote for a purpose, to try to get me to do or buy or think or know something. Sometimes we want to read words that just ARE, that exist just for the hell of it.
