In scale theory, the '''diatonic semitone''', the '''minor second''' or the '''limma''' is the small step of the [[diatonic]] scale. | In scale theory, the '''diatonic semitone''', the '''minor second''' or the '''limma''' is the small step of the [[diatonic]] scale. | ||
In [[just intonation]], an interval may be classified as a diatonic semitone if it is reasonably mapped to [[7edo|1\7]] and [[ | In [[just intonation]], an interval may be classified as a diatonic semitone if it is reasonably mapped to [[7edo|1\7]] and [[24edo|2\24]] (precisely one step of the diatonic scale and one step of the chromatic scale). Do note that 24edo's 2\24 is used as the mapping criteria here rather than [[12edo]]'s 1\12 since 12edo tempers out certain intervals that otherwise qualify as diatonic semitones. | ||
