What is the scansion of "Poetry" by Marianne Moore?

Scansion is the application of notation to poetry to show its metrical or rhythmic qualities. There are many formulas and methods for showing scansion. The most common notation uses / to mark stressed syllables and x to mark un-stressed syllables. (Because this poem is in free verse, I will not be marking feet, as they do not occur within free-verse poetry.)

/ / x / x x x / x x x / x
I, too, dislike it: there are things that are important

x / x x / x
beyond all this fiddle.

/ x x x / x x x / x x / x x
Reading it, however, with a perfect contempt for it,

x x / x x x x /
one discovers that there is in

x / x x x / x x / x x
it after all, a place for the genuine.

/ x x / /
Hands that can grasp, eyes

x x / x / x x /
that can dilate, hair that can rise

x x / / / x x / x /
if it must, these things are important not

x / x
because a

/ / x x / x / x x x / x / x
high sounding interpretation can be put upon them

x x / x x
but because they are

/ x / x x / / x / x / x x
useful; when they become so derivative as to

x / / x / x x x x
become unintelligible, the

/ x / x / x / x x x x
same thing may be said for all of us—that we

/ x x / x
do not admire what

x / x / x x x /
we cannot understand. The bat,

/ x x / x / x x / x
holding on upside down or in quest of

/ x x
something to

/ / x x / x x / / / x x /
eat, elephants pushing, a wild horse taking a roll,

x / x / / x
a tireless wolf under

x / x x / x x / x / x x / / x
a tree, the immovable critic twinkling his skin like a

/ x / x / x /
horse that feels a flea, the base-

x / x / x / x / x x /
ball fan, the statistician—case after case

x x / x /
could be cited did

/ / x / x x / x
one wish it; nor is it valid

x x / x x x / / x / x x
to discriminate against “business documents

x
and

/ x / x x / x x x x / x
school-books”; all these phenomena are important.

x / / x x / x
One must make a distinction

x / x x / / x / x x x /
however: when dragged into prominence by half

/ x
poets,

x x / x x / x x
the result is not poetry,

/ / x / x x x / x x x
nor till the autocrats among us can be

/ x x x x
“literalists of

x x / x x x x /
the imagination”—above

/ x x x / x / x x x x x /
insolence and triviality and can present

x x / x x / x x x / x x / /
for inspection, imaginary gardens with real toads

x x x x /
in them, shall we have

x / x / x x x x / x / /
it. In the meantime, if you demand on one hand,

x x / x x / x / x
in defiance of their opinion—

x / x / x x x / x x x
the raw material of poetry in

/ x / x x
all its rawness, and

/ x x / x / x /
that which is on the other hand,

/ x x / / x / x x x x / x x
genuine, then you are interested in poetry.
