write down the first letters of each words on a piece of paper, or your hand even! then, say the poem, looking at what you wrote down. after that, try it wothout looking at the poem as much, then look at it less and less until youre saying the entire poem only looking at the first letters. try and remember what letter or word starts each verse(or paragraph)and itll help. thats hohw i memorize something..hope it helps!!
