Dew comma
| Interval information |
The comma 180224/177147 is an unnoticeable 11-limit comma that is the difference between 33/32 and the Pythagorean comma. This comma is tempered out in EDOs with gentle fifths like 17edo, 29edo and 46edo, making 11/8 a double-diminished fifth (C-Gbb) 11/9 an augmented second (C-D#), and 27/22 a diminished fourth (C-Fb). This allows for the access of undecimal intervals in the Pythagorean chromatic scale but not the diatonic scale.
