Answer:
If you're trying to memorize something, I'd suggest you'd look over the piece multiple times, and if that doesn't help maybe turn it into a little song that you can remember.
Explanation:
Personally I find making a little song easier to remember, and if that doesn't help, just make sure you keep trying, and maybe even do a little bit of digging on Google to find more things such as songs that have already been made to memorize the piece.
