'''Septimal Canright''' is a [[7-limit]] [[just intonation]] scale used by [[David Canright]] in his [https://archive.org/details/cd_fibbonacci-suite-for-retuned-piano-7-hands_david-canright piano canon for seven hands] and mentioned by him [https://sites.google.com/site/davidrcanright/music-articles/on-piano-retuning in a 1985 article] from the <i>Journal of the Just Intonation Network</i>. It was independently discovered by multiple people and has been known about since 1985 or earlier. It consists of three chains of four 3/2's, the second separated from the first by 5/4 and the third by 14/9, which means that 9 out of 12 notes have a perfect fifth above them and 8 have either a classical major third or a [[56/45|marvelous]] one.
