Like the diatonic semitone, this can benefit from using 2\24 |

A '''chromatic semitone''' or '''augmented unison''' is the [[chroma]] of a [[diatonic]] scale. It is also the large step of a [[p-chromatic]] scale or the small step of an [[m-chromatic]] scale. | |||
[[Category: | In [[just intonation]], an interval may be classified as a chromatic semitone if it is reasonably mapped to [[7edo|0\7]] and [[24edo|2\24]] (precisely zero steps of the diatonic scale and one step of the chromatic scale). The use of 24edo's 2\24 as the mapping criteria here rather than [[12edo]]'s 1\12 better captures the characteristics of many intervals in the [[11-limit|11-]] and [[13-limit]]. | ||
== Examples == | |||
* [[2187/2048]], the Pythagorean chromatic semitone (3-limit) | |||
* [[25/24]], the classic chromatic semitone (5-limit) | |||
* [[1089/1024]], the Alpharabian chromatic semitone (11-limit, specifically 2.3.11 subgroup) | |||
