Linebreaks in Poetry

Sometimes in poetry, poets decide to use Free Verse which uses no rhyme scheme or strict metrical pattern. In my opinion, this helps the reader use more focus towards the words of the poem rather than the pattern scheme. I have noticed in many poems I have read that have a certain metrical pattern, I tend to pay more attention to the word pattern than I do to the meaning of the words.
In William Williams, "A Sort of a Song" he uses linebreaks throughout his poem and does not use a rhyme scheme for any part of the poem. I was able to understand the poem better and focus on the idea Williams was trying to convey since there was not a rhyme scheme involved. For instance in our discussion questions the quote, "No ideas but in things" was in between the two words "Compose" and "Invent" as if to tell the reader to invent their own ideas and thoughts. He placed the quote strategically between these two words in order to express the meaning of what the quote is meant to convey. Had he placed the quote within a line of the poem which rhymed with other lines, I think it would not have been as effective. When Williams wrote,
Let the snake wait under
the weed
and the writing
be of words, slow and quick, sharp
to strike, quiet to wait,
sleepless.
he allowed the reader to create an image of the snake awaiting under the weed as well as the image of a writer writing words to a poem quickly sharply and quietly. The break in the lines and words of the poem allow the reader to use their imagination and create the scene. Williams uses imagery in his line breaks and is able to persuade the reader to use his or her own thoughts to create the remainder of what is to be told.
Using line breaks allows the reader to focus on the meaning of the words and the use of language in poetry. A reptitive rhyme scheme only causes the reader to "read" over the words however they tend not to "understand" the words. I think Williams did an excellent job of using images and Free Verse to convey his thoughts in a poem.
