Delta centauri
| Delta Centauri |
Delta Centauri is the non-octave temperament of the 3.5.11 subgroup that tempers out the 4-cent comma, 1953125/1948617. This temperament is generated by an almost-just 5/3 and stacking it ninefold reaches the representation of 11/9. Basically it is a slightly-tempered 3.5 subgroup. The best tuning is to flatten 5/3 by a fraction of a cent, though just 5/3 or slightly-sharp 5/3 will work too. It is an efficient microtemperament with sub-cent error on the 5th and 11th harmonics in optimal tunings.
