Negri
Negri is a temperament generated by a generator of approximately 125.7549 cents, which can be identified with a tempered 16/15, such that:
- Two of them make a tempered 7/6~8/7~15/13
- Three of them make a tempered 5/4
- Four of them make a tempered 4/3.
It is most naturally viewed as a 2.3.5.7.13 subgroup temperament (tempering out 49/48, 65/64 and 225/224).
It is an important temperament which is most notable for being in 19-EDO, where it is generated by the "diatonic half step" of 2\19, but can also be found (albeit not very accurately) in 9-EDO and 10-EDO.
It forms 9-note MOS's at 1L8s, with the mode ssssLssss being particularly useful as it has 4:5:6's on the 1/1 and 3/2, as well as 10-note MOS's at 9L1s, which is also useful in that it makes 4:5:6 and 10:12:15 share the same "shape" of generic intervals in the scale (as do many decatonic scales.
The 7-limit extensions can also be viewed as joining with the Marvel temperament family; the tuning information below is also located there.
