Rhymes can be useful in remembering concepts and ideas. You may remember these simple rhymes from your childhood, which were designed to teach as well as be fun!

Most little children learn the alphabet by singing the letters to the tune of ‘Twinkle Twinkle Little Star'

Another example which helps to work out the number of days in each month is:
"30 days hath September April, June, and November. All the rest have 31, save February - the shortest one. 28 is all it stores, till Leap Year gives it one day more".
You may have some key words to remember about a particular topic that you could put into a rhyme that you devise. You might even sing or rap it. If you do, you will be very likely to remember it.
