Revision as of 13:51, 28 January 2022 by FloraC (talk | contribs) (+prime error table)

The 422 equal division of the octave divides the octave into 422 equal parts of 2.844 cents each.

422edo is a zeta peak edo, though not zeta integral nor zeta gap. It is distinctly consistent through the 27-odd-limit, with harmonics of 3 through 23 all tuned sharp. In the 5-limit it tempers out the vishnuzma, [23 6 -14; and in the 7-limit 4375/4374 and 589824/588245 so that it supports the gamera temperament, and provides its optimal patent val, and also supports the vishnu temperament. A basis for the 11-limit is 3025/3024, 4375/4374, 5632/5625 and 825000/823543.
