Template:EDO intro

1337edo is consistent to the 13-odd-limit, although the errors of harmonics 5, 7, and 13 are quite large. The equal temperament tempers out 2401/2400 (breedsma), 65625/65536 (horwell comma) and 703125/702464 (meter) in the 7-limit, so that it supports tertiaseptal. In the 11-limit it tempers out 3025/3024 and 41503/41472, so that it supports hemitert.
