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 called '''negra''', and it is realized consistently in [[19edo]] and [[29edo]]. Other tunings which may be usable as a negri or negra temperament include [[9edo]], [[10edo]], [[28edo]], [[47edo]], and [[48edo]], all of which are consistent through (at least) 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]].

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. | ||
Another useful mode of | 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 | 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 | 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 | 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]]. | ||
