Original Wikitext content:
In [[17-limit]] [[Just Intonation]], 17/12 is the "second septendecimal tritone," measuring very nearly 603¢. Its inversion is the "first septendecimal tritone," [[24_17|24/17]], and the interval that separates them is the small [[comma]] [[299_298|299/298]], about 6¢. This difference is usually negligible, and tempering out this comma allows the 600¢ half-octave to function as both septendecimal tritones. Thus, every even-numbered [[EDO]] system contains a close approximation to these intervals. 17/12 is the [[mediant]] between the two septimal tritones [[7_5|7/5]] and [[10_7|10/7]]. See: [[Gallery of Just Intervals]]
