[[Negri]] temperament has various extensions to the [[11-limit]].
[[Negri]] temperament has various competing [[extension]]s to the [[11-limit]]. This is evidenced by the fact that its [[support]]ing equal temperaments, [[10edo|10]] and [[19edo|19]], do less well in the 11-limit. The extensions are:
* '''Undecimal negri''' (10 & 19) – tempering out 45/44, 49/48, and 56/55
* '''Negril''' (10e & 19) – tempering out 49/48, 100/99, 225/224
* '''Negric''' (10e & 19e) – tempering out 33/32, 49/48, 77/75
* '''Negroni''' (10 & 19e) – tempering out 49/48, 55/54, 225/224
 
Another possible path which relates a sense of compromise is to temper out [[121/120]], leading to [[wilsec]]. This has the effect of slicing the generator in two, and is supported by [[20edo|20]], [[29edo|29]], and [[38edo|38df]].
