Editing Semitone (section)

===Other equal temperaments===

[[19 equal temperament|19-tone equal temperament]] distinguishes between the chromatic and diatonic semitones; in this tuning, the chromatic semitone is one step of the scale ({{Audio|1 step in 19-et on C.mid|play 63.2 cents}}), and the diatonic semitone is two ({{Audio|2 steps in 19-et on C.mid|play 126.3 cents}}). [[31 equal temperament|31-tone equal temperament]] also distinguishes between these two intervals, which become 2 and 3 steps of the scale, respectively. [[53 equal temperament|53-ET]] has an even closer match to the two semitones with 3 and 5 steps of its scale while [[72 equal temperament|72-ET]] uses 4 ({{Audio|4 steps in 72-et on C.mid|play 66.7 cents}}) and 7 ({{Audio|7 steps in 72-et on C.mid|play 116.7 cents}}) steps of its scale.

In general, because the smaller semitone can be viewed as the difference between a minor third and a major third, and the larger as the difference between a major third and a perfect fourth, tuning systems that closely match those just intervals (6/5, 5/4, and 4/3) will also distinguish between the two types of semitones and closely match their just intervals (25/24 and 16/15).
