EDOs with a fifth flatter than the 12edo fifth, such as [[19edo]] and [[31edo]], map the pythagorean comma negatively, and thus have a positive diminished second (also known as a diesis). The majority of these EDOs support [[meantone]], which equates the pythagorean major third [[81/64]] to the 5-limit major third [[5/4]]. | EDOs with a fifth flatter than the 12edo fifth, such as [[19edo]] and [[31edo]], map the pythagorean comma negatively, and thus have a positive diminished second (also known as a diesis).
