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. Tempering out this comma makes 11/8 a double-diminished fifth (C-Gbb) and 11/9 an augmented second (C-D#), which allows for the access of undecimal intervals in the brighter modes of the Pythagorean chromatic scale but not the diatonic scale.
