The 22edo fifth, measuring approximately 709.1 cents, is wider than the 702-cent [[3-limit]] fifth, thus making 22edo a "super-pythagorean" system. As with any superpyth, a chain of fifths produces relatively wide major thirds and narrow minor thirds. In the case of 22edo, the thirds are stretched out to the [[7-limit]] ; the [[subminor third]] comes close to [[7_6|7/6]] and the [[supermajor third]] to [[9_7|9/7]]. Thus, the resulting diatonic scale, which no longer approximates 5-limit thirds, sounds oddly consonant. The ratio of major 2nd to minor 2nd in this diatonic scale is stretched out to 4:1, with the M2 falling between 9/8 and [[8_7|8/7]], and the m2 falling close to a quarter-tone. | The 22edo fifth, measuring approximately 709.1 cents, is wider than the 702-cent [[3-limit]] fifth, thus making 22edo a "super-pythagorean" system.

How to Notate 22edo in Sagittal | |||
When 22edo is treated as a (super)pythagorean system, the naturals F C G D A E B represent a chain of 13\22 fifths; consequently, the whole tone comes out to four degrees and the apotome (pythagorean sharp/flat) comes out to three degrees. Three pairs of sagittal symbols, dividing that apotome into three parts, are all that is necessary: | |||
