I memorize by using mnemonics, that is by using the first letters of each word to form a new word as a formula or words that rhyme which can be easily recognized or remembered.
Example in Music:
Key of E = every
Key of G = good
Key Of B = boy
Key of D = does
Key of F = fine
Key of A = always
Or Roy G. Biv for the colors of the rainbow or spectrum.
Or Pvt. Tim Hall = Essential amino acids (Phenylanine, Valine, Threonine, Tryptophan, Isolucine, Histidine, Arginine, Leucine, Lysine.
