Mnemonic Devices

From Xenharmonic Wiki
Jump to: navigation, search

A mnemonic device is a technique a person can use to help them improve their ability to remember something. (Think of "PEMDAS" for remembering the standard order of operations in arithmetic.) In xenharmonics, the creation and collection of mnemonic devices may prove useful in aiding or even bypassing tuning computations.

Nonoctave interval poem-setting

A fun and kooky way to convert a string of numbers into a songlet.

  1. Identify an interval of interest. Convert it to cents, to the thousandths place. 3/2 = log(3/2)/log(2)*1200 ≈ 701.955¢
  2. Write a poem wherein each digit will correspond to a word with that number of letters. For zero, find a 10-letter word. 11-, 12-, etc. letter words are also permissible. Raisins, applejacks, 'n' Béarnaise sauce: crunk!
  3. Set that poem to music using only the interval of interest. Left as an exercise to the reader.

A set of nonoctave interval mnemonics were created for 17edo and included in the fledgling edition of The Sagittal Songbook. Take a look, try 'em out! File:Jarband's nude rainbow.pdf

53EDO: Try it!

Let's try making nonoctave intervals for 53edo! I've listed the cents values for the degrees of 53edo below. When the inspiration strikes, pen a one-line poem and list it here. (It's okay to have competing poems for the same interval value.) Then, set it to music, or get someone else to. (But before you do that, double-check that the digits and letter counts match!)
