User:VectorGraphics/Singularity
Singularity is the regular temperament that tempers out 1/0, the singularitone, setting its value equal to 1, the unison. While this at first appears to do nothing to conventional JI, this changes when you realize that because 1/0 contains all possible factors in its numerator (because it can be written as 2/0 or 3/0 or 5/0 or 7/0 etc), that that implies that every single interval, in all limits, is tempered out.
This means that singularity is the most inaccurate possible temperament. It is even less accurate than 0edo, which could hypothetically represent the notes at 0 and 1/0 as distinct notes from 1/1 in a mathematical context.
