It is the difference between [[69/68]] and [[70/69]]. By tempering it out is defined the &#039;&#039;&#039;demiquartervice temperament&#039;&#039;&#039;, which enables the [[demiquartervice chords]].<br /> <br /> == Etymology ==<br /> The words &#039;&#039;demiquartervice&#039;&#039; and &#039;&#039;demiquartervicema&#039;&#039; were introduced by [[User:Xenllium|Xenllium]] in 2023. Both were so named for the following reason – rational intervals [[69/68]] and [[70/69]] are mapped to 1/48 of an octave (25¢, demi-quartertone, halfway between both ratios) in some EDOs of the 48&#039;&#039;n&#039;&#039;-edo family (such as [[48edo]] and [[240edo]]).<br /> <br /> == See also ==<br /> * [[Unnoticeable comma]]<br /> * [[List of superparticular intervals]]<br /> <br /> [[Category:Demiquartervice]]<br /> [[Category:Commas named for their regular temperament properties]]</div>
