Hack #5. Use the Major System

The Major System is the most commonly used set of mnemonics. This custom Major System will help you memorize lists of up to 100 items, as well as credit card PINs, phone numbers, and the other numeric trivia of daily life.

The Major System was introduced in the 17th century by Stanislaus Mink von Wennsshein and was improved in the 18th century by Dr. Richard Grey.1 While the Major System is probably the most established mnemonic schema, I prefer the Dominic System [Hack #6], invented by Dominic O'Brien in the 20th century. Nevertheless, you might find that the Major System works well for you, and knowing something about it will contribute to your understanding of advanced mnemonic techniques.

In Action

The Major System uses peg words just like the number-rhyme system [Hack #1] and number-shape system [Hack #2]. Instead of associating numbers with peg words based on rhymes or shapes, however, it assigns each digit a basic consonantal sound and builds up peg words from combinations of those consonants. For example, the digit 3 is linked to the consonant M, and the digit 2 is linked to the consonant N, so our Major System list suggests moon for 32.

The consonant assignments are fairly arbitrary—Lewis Carroll came up with an alternate set [Hack #9] that's probably just as good—but Table 1-2 shows a standard set of mnemonics you can use for these associations until they become second nature.

Table 1-2. Number/letter associations

NumberLetterAssociation
0S, Z, soft CZ is the first letter of zero.
1D, T, THThe letters d and t have only one downward stroke.
2NThe letter N has two downward strokes; it also looks like the numeral 2 rotated 90 degrees.
3MThe letter M has three downstrokes; it also looks like the numeral 3 rotated 90 degrees.
4RThe letter R is the last letter in four.
5LL is the Roman numeral for 50; also, a human hand with its thumb stuck out looks like an L.
6J, SH, DG, soft G, CH as in cheeseJ looks like 6 backward.
7K, hard C, hard G, QU, CH as in lochYou can draw a K with two 7 characters.
8F, VA cursive, lowercase f looks like an 8.
9B, PA b looks like a 9 rotated 180 degrees; a P looks like a backward 9.

Table 1-3 shows the Major System peg word list for the numbers 1 to 100. If you don't like the words I use, you can use your own. Since your list will use your own mental connections, it might be even more effective for you. Just be consistent, so you don't have to grope to remember the peg word for a particular number.

When you're converting numbers to peg words and back, there are some simple rules to follow:

  • Ignore vowels.

  • Ignore the second consonant in double-consonant sounds. For example, mummy is 33, not 333, because the mm is counted as a single m.

  • Ignore silent consonants. For example, neck is 27, not 277, because the C does not contribute to the K sound.

Tip

To make these rules more obvious, Table 1-3 capitalizes only the consonants being used to form the peg word. For example, the peg word for 32 is listed as MooN.

Since there are only a limited number of possible words in English for each number, the mnemonic lists for the Major System in most memory books tend to be similar. I consulted three of the books in my collection2,3,4 to compile this list, taking the best from each and adding my own words (such as 42 = RaDio and 81 = VaT) when it seemed useful. I followed several guidelines, which might interest you if you want to customize it:

  • I preferred nouns to verbs and adjectives, because they are more easily visualized.

  • I preferred concrete objects to abstract objects for the same reason.

  • I preferred more active, versatile objects (49 = RoPe, not RuBy), ditto.

  • I tried not to interfere with other memory systems in this book (for example, deleting 99 = PiPe because it might interfere with 6 = pipe in the number shape system) or other Major System items (for example, 95 = BeLl interfered with 63 = ChiMe).

In Real Life

If you have a credit card with the number 4880 6630 6767 7584 (these digits were generated at random with the dice-rolling application on my PDA), you might remember them with the words shown in Table 1-4.

Table 1-4. Associations for a credit card number

NumberWord
48Roof
80Vase
66Choo-choo
30Moose
67Chalk
67Chalk
75Coal
84Fur

But now you have a new problem: how are you going to remember this arbitrary list of words, especially the two sequential instances of chalk?

You can use the following little story—a kind of memory journey [Hack #3]—to string them together:

A shingle falls off your roof and breaks a vase. A choo-choo of the sort in a kiddie amusement park chugs up and the conductor gets out. He's a moose! He scolds you and tries to write you up with a piece of chalk, but his slate is also made of chalk. (How weird.) He bellows in frustration and begins shoveling coal to leave, but he gets sooty, and abashedly asks you to brush out his fur.

With just a few mental rehearsals of this story (or the equivalent for your own card), you just might never forget your credit card number again. If you actually recall the number a few times in the bustle of real life, you'll begin to remember the number directly and let the story fade naturally.
