'''14/13''', the '''2/3-tone''' or '''trienthird''' (one-third third), nicknamed the '''sinaic''' (after Ibn Sina who used it in one of his scales) | '''14/13''', the '''2/3-tone''' or '''trienthird''' (one-third third), nicknamed the '''sinaic''' by [[Zhea Erose]] (after Ibn Sina who used it in one of his scales), is a somewhat exotic 13-limit interval measuring about 128.3¢, which is almost exactly 1/3 of a [[5/4]] major third- a stack of three trienthirds falling short of a 5/4 major third by a [[10985/10976|cantonisma]]. | ||
The trienthird was a favorite interval of [[Wikipedia:Avicenna|Avicenna]] (Ibn Sina) for his scale constructions, and may be considered a smaller size of neutral second (a second between major and minor). Thus intervals close in size to it have been called ''sinaics''. | The trienthird was a favorite interval of [[Wikipedia:Avicenna|Avicenna]] (Ibn Sina) for his scale constructions, and may be considered a smaller size of neutral second (a second between major and minor).
