In [[17-limit]] [[just intonation]], '''30/17''' is the '''diatismic minor seventh''', measuring about 983.3{{cent}}. It falls short of the [[16/9|Pythagorean minor seventh (16/9)]] by a [[136/135|diatisma (136/135)]], hence the name. It is the [[mediant]] of [[7/4]] and [[23/13]]. Its inversion is [[17/15]], the "septendecimal whole tone"; both of these intervals are well approximated in [[22edo]] (18\22, 4\22).
