26th-octave temperaments: Difference between revisions

correct the "26-comma is not tempered out" - it is by definition also a 26th-octave tempereament, even if a bad one, and document with corresponding style while acknowledging how innacurate it is

+26/7 comma, or fynn if following naming logic, + style

26edo is very accurate for 7th harmonic, the [[26-7-comma]] ({{monzo| 73 0 0 -26 }}, the amount by which 26 septimal whole tones ([[8/7]]) exceed 5 octaves) is tempered out by 26-fold multiple edos up to 1456 (such as [[26edo|26-]], [[130edo|130-]], [[286edo|286-]] or [[546edo|546edo]]).

The 26-commatic temperament tempers out the [[26-comma]], {{monzo|-41 26}}. 26edo is notable for having a flattone fifth, and due to large error, 26edo and its double, [[52edo]], are the only temperaments tempering out this comma. Hence it primarily serves as an object of mathematical interest.
The ''26-commatic'' temperament tempers out the [[26-comma]], {{monzo|-41 26}}. 26edo is notable for having a flattone, even if innacurate, fifth, which has seen some attention in music theory. Due to large error, 26edo and its double, [[52edo]], are the only temperaments tempering out this comma. Hence it primarily serves as an object of mathematical interest.
