26\37 = 843.2 cents
26\37 = 843.2 cents


This means 37 is quite accurate on the 2.5.7.11 subgroup, where it shares the same tuning as 111et. In fact, on the larger [[k*N subgroups|3*37 subgroup]] 2.27.5.7.11.51.57 subgroup not only shares the same tuning as 19-limit 111et, it tempers out the same commas.

"minor third" = 8\37 = 259.5 cents
"minor third" = 8\37 = 259.5 cents
"major third" = 14\37 = 454.1 cents
"major third" = 14\37 = 454.1 cents
If the minor third of 259.5 cents is mapped to 7/6, this superpythagorean scale can be thought of as a variety of [[The Biosphere|Biome]] temperament.


37edo has great potential as a xenharmonic system, which high-prime chords such as 8:10:11:13:14 with no perfect fifths available for common terrestrial progressions.
