Types of Mnemonic Devices

There are at least nine different kinds of mnemonic devices. These are some of the most popular and useful:

  • Musical mnemonics. The alphabet song is an example of this kind of mnemonic device that makes it easy to memorize all the letters in order.
  • Name mnemonics. To use this approach, you create a name made up of the first letters of the sequence you want to memorize. For example, if you can remember the name Pvt. Tim Hall, you have a handy tool for remembering the essential amino acids (Phenylalanine, Valine, Threonine, Tryptophan, Isoleucine, Histidine, Arginine, Leucine, Lysine).
  • Phrase mnemonics. If you can remember the expression "Kings Play Cards On Fairly Good Soft Velvet," you can recall the order of the categories in the classification of life: Kingdom, Phylum, Class, Order, Family, Genus, Species, Variety.
  • Rhyme mnemonics. In what year did Columbus sail from Spain to America? "In fourteen hundred and ninety-two Columbus sailed the ocean blue."
