'''Negri''' is a [[regular temperament]] generated by a [[generator]] of approximately 126 [[cent]]s, which can be identified with a tempered [[16/15]], such that:

* Two of them make a tempered [[7/6]]~[[8/7]]~[[15/13]]

It is most naturally viewed as a 2.3.5.7.13 [[subgroup]] temperament, [[tempering out]] [[49/48]], [[65/64]] and [[91/90]]. This is sometimes called '''negra''', and it is realized consistently in [[19edo]] and [[29edo]]. Other [[edo]]s which may be usable as a negri or negra tuning include [[9edo]], [[10edo]], [[28edo]], [[47edo]], and [[48edo]], all of which are [[consistent]] through (at least) the [[5-odd-limit]], since in the broadest sense, negri is defined as tempering out the [[negri comma]] in the [[5-limit]].

It is most naturally viewed as a 2.3.5.7.13-[[subgroup]] temperament, [[tempering out]] [[49/48]], [[65/64]] and [[91/90]]. This is sometimes called '''negra''', and it is realized consistently in [[19edo]] and [[29edo]]. Other [[edo]]s which may be usable as a negri or negra tuning include [[9edo]], [[10edo]], [[28edo]], [[47edo]], and [[48edo]], all of which are [[consistent]] through (at least) the [[5-odd-limit]], since in the broadest sense, negri is defined as tempering out the [[negri comma]] in the [[5-limit]].

Negri ~~is generated by a large "semitone" of around 125 cents and~~ forms 9-note and 10-note [[mos]]ses, ~~negri~~[9] and ~~negri~~[10], at [[1L 8s]] and [[9L 1s]] respectively. In [[19edo]], the negri generator is the "diatonic half step" of 2\19, which allows these mosses to be written fairly simply in conventional notation. For example, the ssssLssss mode of 19edo could be written as E F Gb G# A B C Db D# E. This mode is particularly useful as it has identical ssss pentachords (analogous to the [[tetrachord]]s of classical Greek music theory) on the 1/1 and 3/2. It is also notable in that a subset of these notes form the E Double Harmonic Major scale, E F G# A B C D# E, which features in a wide variety of world musical traditions. In fact, all modes of ~~negri~~[9] and ~~negri~~[10] contain at least one mode of the double harmonic scale as a subset.

Negri forms 9-note and 10-note [[mos]]ses, Negri[9] and Negri[10], at [[1L 8s]] and [[9L 1s]] respectively.

In fact, all modes of Negri[9] and Negri[10] contain at least one mode of the double harmonic scale as a subset.

Another useful mode of ~~negri~~[9] is Lssssssss, which in 19edo would be A B C Db D# E F Gb G# A. This has a minor triad (~~A-C-E~~) for a tonic chord, which can be extended to a 7-limit utonal tetrad (~~A-C-E-D~~#), as well as 7-limit otonal tetrads on E and F that can function as, respectively, a dominant seventh chord and a German ~~Augmented Sixth~~ chord. This scale also contains the popular Hungarian ~~Minor~~ mode of the ~~Double Harmonic~~ scale, A B C D# E F G# A.

Another useful mode of Negri[9] is Lssssssss, which in 19edo would be A B C Db D# E F Gb G# A. This has a minor triad (A–C–E) for a tonic chord, which can be extended to a 7-limit utonal tetrad (A–C–E–D#), as well as 7-limit otonal tetrads on E and F that can function as, respectively, a dominant seventh chord and a German augmented sixth chord. This scale also contains the popular Hungarian minor mode of the double harmonic scale, A B C D# E F G# A.

4 of the 9 modes of ~~negri~~[9] are like the Locrian mode of the diatonic major scale in that they do not have a note a perfect 5th above the tonic. These are more difficult to apply conventional music theory to. However even in these modes there are a number of chords built on the tonic that can provide a measure of consonance and stability, such as 13:16:20:24 and 6:7:8.

Negri[10] also has a number of useful features. One of these features is the fact that it makes 4:5:6 and 10:12:15 share the same "shape" of generic intervals in the scale (as in other rank-2 decatonic scales such as [[pajara]] and [[blackwood]] scales; this is because 5/4 and 6/5 get tempered to the same thing in [[10edo]]).

The 7-limit version can also be viewed as joining with the [[marvel]] temperament family. See [[~~Slendro~~ clan #Negri]] for more technical data. For the various 11-limit extensions, see [[negri extensions]].
