~~~~The 41.059 cent interval of '''128/125''' is called the '''diesis''' or '''augmented ~~[[Comma|~~comma]]'''; it represents the gap between three [[~~5/4|~~5/4]] just major thirds and the [[~~Octave|~~octave]], or in other words 2/(5/4)^3. It is fairly accurately represented by a single step in [[28edo|28]], [[31edo|31]] or [[34edo~~|34~~]] ~~EDO~~, and by two steps of [[53edo|53]], [[59edo|59]] or [[65edo~~|65~~]]. In any tuning with just major, thirds, such as [[~~Quarter~~-~~comma_meantone|quarter~~ comma meantone]], it will be exact.

The 41.059-[[cent]] interval of '''128/125''' is called the '''diesis''' or '''augmented comma'''; it represents the gap between a stack of three [[5/4]] just major thirds and the [[octave]], or in other words 2/(5/4)3.

== Approximations ==

This interval is fairly accurately represented by a single step in [[28edo|28-]], [[31edo|31-]] or [[34edo]], and by two steps of [[53edo|53-]], [[59edo|59-]] or [[65edo]]. In any tuning with pure octaves and just major thirds, such as [[quarter-comma meantone]], it will be exact. Furthermore, in meantone it appears as the difference between sharps and flats, e.g. between D# and Eb. It is also called '''enharmonic diesis''' or '''enharmonic comma''' for this reason.

== Temperaments ==

=== As a comma ===

[[Tempering out]] this comma leads to [[augmented]] temperament. See [[augmented family]] for the family where it is tempered out.

=== As an interval ===

If the diesis is treated as a musical interval in its own right as opposed to tempering it out, it is approximately a quarter-tone and so can be used to introduce [[7-limit]] and [[11-limit]] harmony into 5-limit scales.

== Trivia ==

This interval represents the amount by which the binary definition of kilobyte, 1024 bytes, exceeds the nominal definition of "kilo" prefix, 1000.
