Luna and hemithirds: Difference between revisions
m Lériendil moved page Hemithirds to Luna and hemithirds: Luna is the 2.3.5 restriction of hemithirds; people have referred to "luna" on various occasions while they were truly referring to hemithirds; the actual septimal extensions of luna are, while microtemps, inordinately complex compared to hemithirds; therefore I believe that for most practical purposes hemithirds can be considered "the" septimal extension of luna unless working in 441, 559, 1000edo, etc. |

The '''hemithirds''' temperament | The [[7-limit]] '''hemithirds''' temperament functions as a strong extension of [[didacus]], the 2.5.7 subgroup temperament, in the range between [[25edo]] and [[31edo]] tuning, defined by tempering out [[3136/3125]] such that two of its generators (hemithird, [[~]][[28/25]], around 193.2 [[cent]]s) reach ~[[5/4]], three reach ~[[7/5]], and therefore five reach ~[[7/4]]. Hemithirds extends didacus by tempering out [[1029/1024]], such that three intervals of ~[[8/7]] reach [[3/2]], therefore finding [[4/3]] after fifteen generators in total. | ||
See [[Hemimean clan #Hemithirds]] for more information. | '''Luna''' is a restriction of hemithirds to the [[5-limit]] that is a [[microtemperament]], supported by such high-precision tuning systems as [[118edo]] and [[441edo]]; another notable tuning of luna is [[1000edo]]. It can further be re-extended to the 7-limit in the form of [[lunatic]], but that extension is extremely complex (finding the 7th harmonic at 113 generators down). | ||
