The name '''triatonic''' was coined by [[User:CompactStar|CompactStar]], | The name '''triatonic''' was coined by [[User:CompactStar|CompactStar]], as a back-formation from "diatonic" with di- being interpreted as 2 (the [[2/1|octave]]) and tri- being interpreted as 3 (the [[3/1|tritave]]), though it is not an official name in [[TAMNAMS]]. | ||

{{MOS scalesig|5L 2s <3/1>}} is a [[macrodiatonic and microdiatonic scales|macrodiatonic scale]] with the period of a [[3/1|tritave]]. This means it is a [[5L 2s|diatonic scale]], but its intervals are all stretched to the point of being unrecognizable—the diatonic fifth is now the size of a major seventh, and octaves are stretched out to tritaves. Interestingly, [[19edt]], an approximation of [[12edo]], has a tuning of this scale, meaning it contains both a diatonic scale (which approximates 12edo's diatonic scale) and a triatonic scale. | |||
