Small comma

A small comma is a comma whose size is approximately between 3.5 and 30 cents. These intervals are in the range from just noticeable up to usable as melodic steps. The actual perception of course varies. In Sagittal notation, intervals in the smaller part of this category are kleismas, and intervals in the larger part of this category are commas.

For commas over 100 cents in size, see Large comma; for commas in between 30 and 100 cents in size, see Medium comma; and for commas under 3.5 cents in size, see Unnoticeable comma.

Due to the wide range of sizes, cents values here and on the other commas pages are listed to 5 significant digits, instead of to a fixed number of decimal places as is the convention elsewhere on the wiki.

The commas might be numerous, but there is no need to memorise all the names. For pretty much all use cases, it is perfectly acceptable to just refer to a comma by the monzo or ratio, whichever is simpler.
