Some explanation: Here I have tried to create a logical, internally consistent way to refer to the various intervals of the microtonal division of the octave into 31 steps (as opposed to the more common 12 steps), 31-tone equal temperament, or 31tET.

Each interval "shortname" I've devised has exactly two simple syllables of two letters to facilitate its easy & speedy utterance. I have taken a set of common names for the intervals already in existence & used them as a jumping-off point. You'll notice I've done away with the words subminor, supermajor, diminished, & augmented in favor of the more consistent lesser & greater. In a system with more notes, those types of distinctions could prove important, but I believe it gets in the way here, so I've simplified.

Below I have listed the two-letter particle words. In each case, at least one prominent letter (often two) of the original word you will find in its particle. You'll notice that I've changed some vowels from the original words. I did this to ensure that the particles sound distinct from one another. I have made sure that all five vowels appear in the suffixes & prefixes. You'll also notice that I've reversed the order of letters from some of the original words. I did this to put each particle in consonant-vowel form, to allow it to function cooperatively with the other particles to aid pronunciation.


le- :: lesser.

mi- :: minor.

nu- :: neutral.

ja- :: major. Note letter reversal. You could pronounce it jah or jay, although I prefer the former.

go- :: greater. I changed the vowel for variety.

pr- :: perfect. Pronounce it like per.


-su :: unison. Note letter reversal.

-to :: tone, as in second.

-di :: third. Note letter reversal.

-fo :: fourth.

-tr :: tritone. Altho it's three letters, tri also works very well, & may sound better to you.

-fi :: fifth. Pronounce like fee.

-xa :: sixth. I changed the vowel for variety.

-vu :: seventh. I changed the vowel for variety.

-co :: octave. Note letter reversal.
