What is the use of rhyming words in a poem?

Sometimes i like poetry that rhymes..and sometimes not- I think it just depends on the type of writing the poetry is, the kind of 'feel' that the one who wrote it is trying to get across along with the words' meaning themselves.. To certain poems, it gives a feeling of 'flow'...and can be pretty profound when you consider the added burden of trying to get across a meaning, a feeling, using words that rhyme on top of the rest~ But the best poems i have ever read, there was little or no rhyme, for it was not ever 'needed'~

There are many diffrent types of poem. there are those who follow the classic rule with rhyming and all that but there are those who follow modern trend which does not have any trend. The use of rhyming is harder to be made and more beutiful and more like romantic and elegant if its done. But the modern writing can be looked as creative and not outdated and can be related to nowadays condition of the world. Both of them are good types of poem. The significance is that the poem lover will notice the rhyming and know how difficult it is to make the rhyming. It doesnt take just anyone to be able to make such a poem. I will give you an example of poem that follow modern trend Here it is: Our World We have no reason to harbor any mistrust against our world, for it is not against us. If it has terrors, they are our terrors. If it has abysses, these abysses belong to us. If there are dangers, we must try to love them, and only if we could arrange our lives in accordance with the principle that tells us that we must always trust in the difficult, then what now appears to us to be alien will become our most intimate and trusted experience. How could we forget those ancient myths that stand at the beginning of all races--the myths about dragons that at the last moment are transformed into princesses. Perhaps all the dragons in our lives are only princesses waiting for us to act, just once, with beauty and courage. Perhaps everything that frightens us is, in its deepest essence, something helpless that wants our love. So you must not be frightened if a sadness rises before you larger than any youve ever seen, if an anxiety like light and cloud shadows moves over your hands and everything that you do. You must realize that something has happened to you. Life has not forgotten you, that it holds you in its hands and will not let you fall. Why do you want to shut out of your life any uneasiness, any miseries, or any depressions? For after all, you do not know what work these conditions are doing inside you. Hope this helps. I think you know already what rhyming poems looked like

Different forms of poetry have different rules: some forms call for rhyming couplets (the last word of each line rhyming with each other), some call for alternate last words to rhyme, and some don't need any of the words to rhyme. Because poetry is a more musical (the sounds of the words, and the way they flow or don't flow, are very important) and emotive way to use language, there are rules to follow according to the type of poem, as a framework within which to be expressive. If you're writing a poem, and udr two words which rhyme or sound similar, this will create a "consonance", which has two effects within the poem - they sound harmonised, and those words stand out and become more significant within the poem. In poetry, every word has to have a reason for being used, and a reason for being where it is, in relation to the other words. Hope that helps! Also, if you choose to break the rules of the form of poetry you're using, you can, but you must have a valid reason to do so within the context of the poem.
