These types of comma names are derived from [[sagittal notation]]. Many ~~of these~~ were named using the spreadsheet

These types of comma names are derived from [[sagittal notation]].

These sagittal names can occasionally get mixed up with the closing-error type of name described earlier. For example "5-comma" is actually a sagittal name, even though it looks like the same type of thing as "31-comma" which is a closing-error type name. These clashes are unfortunate, but not fatal, as a look at the comma's page should reveal which system makes the most sense for interpreting its name.

Many comma pages with sagittal names were named using the spreadsheet

[[File:CommaNamer.xls]], which was made in 2004.

Rounded to 1 decimal place, this was how the spreadsheet named interval size ranges:

* Less than 1.8 cents = schismina or atom

* 1.8 to 4.5 = schisma (''or skisma, skhisma'')

* 4.5 to 11.7 = kleisma (''or semicomma'')

* 11.7 to 35.2 = comma (''or dischisma, diaskhisma, chroma'')

* 35.2 to 45.1 = minor-diesis (''or small-diesis, 1/5-tone, chroma'')

* 45.1 to 56.8 = diesis (''or medium-diesis, 1/4-tone, chroma, enharmonic-diesis, enharmonic'')

* 56.8 to 68.6 = major-diesis (''or large-diesis, 1/3-tone'')

* 68.6 to 78.5 = chromatic-semitone (''or small-semitone'')

* 78.5 to 102.0 = limma (''or medium-semitone'')

* 102.0 to 111.9 = diatonic-semitone (''or large-semitone'')

* 111.9 to 115.5 = apotome

* 115.5 to 118.2 = schisma-plus-apotome

* 118.2 to 125.4 = kleisma-plus-apotome

* 125.4 to 148.9 = comma-plus-apotome

* 148.9 to 158.8 = minor-diesis-plus-apotome (''or neutral second'')

* 158.8 to 170.5 = diesis-plus-apotome

* 170.5 to 182.3 = major-diesis-plus-apotome

* 182.3 to 192.2 = chromatic-semitone-plus-apotome

* 192.2 to 215.6 = limma-plus-apotome

* 215.6 to 225.6 = diatonic-semitone-plus-apotome

* 225.6 to 229.2 = double-apotome

* Over 229.2 = outside the scope of this system

In this context, the term "chroma" implied an absolute 5-exponent of 1 within this system. (But in wider xenharmonic usage, [[chroma]] is pretty vaguely defined and that does not necessarily apply).

The spreadsheet advised not to use the "plus-apotome" names unless the interval is being considered first and foremost as a comma and not a scale degree.
