"Kleisma" is a term with several related uses in music theory, to refer to small comma-sized intervals or intervals with a certain function in a scale.{{Wikipedia}}
|Name=Kleisma
The '''kleisma''' most commonly refers to:
|Cents lower=6
* The interval [[15625/15552]];
|Cents upper=9
* By extension, a melodic unit of about the size of 15625/15552 (≈ 8.1{{cent}}). See [[Kleisma (interval region)]];
|JI intervals=15625/15552, 225/224, 1029/1024, 16875/16807, 65536/65219
* In scale theory, the difference between a [[chroma]] and a [[Diesis (scale theory)|diesis]], more precisely a '''moskleisma''', as used in [[extended meantone notation]].

A '''kleisma''' is an interval of about 8.1 cents, roughly the size of the interval [[15625/15552]], which is called a kleisma in just intonation.\


As an interval region, the kleisma is significant as it is a limit of intonational fidelity when playing on some physical instruments. That is, on free-pitch instruments, there is a level of precision to which one can be expected to play a note or interval "correctly": that level of precision is the kleisma.
{{Disambiguation}}
 
Kleismas belong to the larger interval region of [[Comma (interval region)|commas]], which are part of the [[Comma and diesis|"comma and diesis"]] category.
 
== Other definitions ==
 
* In [[sagittal notation]], it is defined specifically as between half of the 200-comma ({{monzo| 317 -200 }}) and half of the [[Pythagorean comma]] ({{monzo| -19 12 }});
* In scale theory, the difference between a [[chroma]] and a [[Diesis (scale theory)|diesis]] is called a kleisma, or more precisely a '''moskleisma''', as used in [[extended meantone notation]].
