~~'''[[EDT|Division of the third harmonic]] into 19 equal parts''' (19ED3) is related to [[12edo|12 EDO]], but with the 3/1 rather than the 2/1 being just.~~ It is also known as '''Stopper tuning'''~~. The octave is about 1.2347 cents stretched and the step size is about 100.1029 cents~~.

19edt is not a truly [[xenharmonic]] tuning; it is a slightly stretched version (with an octave of 1201.2 cents) of the normal [[12edo|12-tone scale]]. Although it is really just the normal 12edo framed in a pure-3 tuning, it can still be used as a temperament with no twos like other tritave-equivalent tunings, although limited in [[accuracy]], with [[5/3]] approximated as 9 steps and [[7/3]] approximated by 15 steps. It completely misses the next tritave-reduced prime harmonic, [[11/9]].

19 equal divisions of the tritave is not a "real" xenharmonic tuning; it is a slightly stretched version (with an octave of 1201.2 cents) of the normal [[12edo|12-tone scale]]. Although it is really just the normal 12edo tuning framed in a tritave equivalence, it can still be used as a temperament with no twos like other tritave tunings. This approach can create very non-standard chords and scales such as the approximation of the 5:7:9 chord as ~~0-600-1100~~ cents. These could be considered xenharmonic in a sense, since they have little connection to standard 12-tone practice in spite of using the 12-tone interval set. The "default" approach to it is as ~~the tritave twin of~~ godzilla temperament (with a generator of 400.4 cents and a 3:1 ratio ~~superdiatonic~~ scale, ~~weird~~ coincidence how ~~17EDT~~ and ~~19EDT~~ tonality have the same "default" scheme with two tones more or less). Beyond this, it is also the tritave twin of ~~sensi or~~ meantone temperament (with a generator of 700.7 or ~~1101~~.1 cents), producing a basic [[8L 3s (3/1~~-equivalent~~)|~~Obikhod~~]] ~~scale~~.

This approach can create very non-standard chords and scales such as the approximation of the 5:7:9 chord as 0–600–1000 cents. These could be considered xenharmonic in a sense, since they have little connection to standard 12-tone practice in spite of using the 12-tone interval set. The "default" approach to it is as a "macro-[[godzilla]]" temperament (with a generator of 400.4 cents and a 3:1 ratio {{mos scalesig|5L 4s<3/1>|link=1}} scale, and it is an interesting coincidence how [[17edt]] and 19edt tonality have the same "default" scheme with two tones more or less). Beyond this, it also contains the tritave twin of [[meantone]] temperament (with a generator of 700.7 or 1201.2 cents), producing a basic {{mos scalesig|8L 3s<3/1>|link=1}} scale.
