repetition.repetition.repetition. i am visual...so when i would memorize my lines for plays (yes, lots of Shakespeare here)..i would write all my cues and lines out word by word on paper. then i would do every third word. then every fourth etc, until i needed only one or two words per huge section. then by the time i was done doing that, i had it all memorized... i did this same thing for spanish class and never really had to study. worked for me...if you are more auditory, i would suggest you try recording yourself saying each section of the script and playing it back on your iPod or in your car.
Its really hard to memorize a script,what you have to do is to understand the script and feel as if you are really the character.relax and be confident.it can make the lines more beautiful on the way you deliver it.have fun and just take is easy.
Don't just try and cram it all in your brain, force yourself to memorize it and then comprehend it. Comprehend it and then memorize, it'll be so much easier because you get a better picture of your character or whatever it is that your playing. And don't try and memorize it all like the night before the play if it's like a booklet! Do a little bit everyday and rehearse it at some point before you go to bed or something to make sure you got it. Also, wrote memorization helps a looooot. Writing your lines over and over again. It'll bore you and kind of annoy you, but it'll actually get stuck in your brain and you don't even have to think as much to regain it. (:
look at your lines , say them out loud how you would say it on stage. confidential , loud and proud as I was saying, after you read your lines without looking in the mirror, say it in the mirror and you will remember it. Because, your brain recognises it, from you saying it in the mirror. it makes you remember it like bingbangboom! I promise you, you will not be disappointed.
