'''361/360''', the '''go comma''' or '''dudon comma''', also described as the ''undevicesimal semitones comma'', is a [[19-limit]] (also 2.3.5.19 [[subgroup]]) [[superparticular]] [[comma]] of about 4.8 [[cent]]s. It is the difference between [[19/18]] and [[20/19]], the two undevicesimal semitones, as well as between [[19/15]] and [[24/19]], the two undevicesimal major thirds. It is also the difference between two stacked [[19/18]] and [[10/9]]. By tempering it out is defined the '''dudon temperament''', which enables the [[dudon chords]].
