A good example of the use of music mnemonics is:

A. singing the ABC song to learn the alphabet.

B. using the phrase "Please Excuse My Dear Aunt Sally"
(parentheses, exponents, multiply, divide, add, subtract) to
remember the order of math operations.

C. using the word HOMES (Huron, Ontario, Michigan, Erie, Superior)
to remember the Great Lakes.

D. remembering that a school principal is your pal.
