One of the worst problems poets, especially ones just starting to find their pace have, is the problem of rhythm.  All of the great poems in the world have at least some semi-balance of rhythm within their work.  The easiest way to both get rhythm and to kill a good poem is by rhyming the lines.  It can be the death of a poem, removing words that hold a deep meaning to replace them with useless sounds and letters signifying nothing deeper then what a two year old can read in it.  If it works for you then great but I don’t recommend even trying to rhyme your poem unless it starts out that way naturally.  The second way I will show you is far less used and is even less recognized by the beginning poet.  The power of cacophony and euphony are overwhelming inside a poem.  For those of you who don’t know what these are and are probably thinking I made these words up, cacophony is a sound device that is used to create a harsh environment around your poem.  It involves the use of harsh letters found reoccurring within a poem or stanza.  Letters like r, k, and t as well as sounds ch, a hard c sound.  The use of cacophony emboldens the harsher side as well as makes a depressing poem much more effective.  Also when sounds such as these tend to occur it creates a form to the poem and the way the audience would read it.  Euphony is the use of softer sounds in the same manner as cacophony.  It creates a much more soft peaceful effect to the poem and it accents and mood with wisdom and grace.  It will often slow down the pitch of a poem quite well.  The third and final tactic that poets should use to edit their poems is stanza spacing.  Find an individual rhythm for each stanza instead of trying to do the whole poem in one base form.  This is much easier to do then setting up euphony or cacophony and is as effective as rhyming your poem without killing too much of the word structure.  I hope that this guide will help you understand how to edit your poems, please send in any constructive criticism or any other things that should be added to the guide, Thanks and good luck!
