Temperament naming: Difference between revisions

Confusingly, in [[Jean-Philippe Rameau]]'s [[Treatise on Harmony]] from 1722, he called [[2048/2025]] the "diminished comma", and so in a way "diminished temperament" should already have been considered taken; the modern name for 2048/2025, the diaschisma, which gives its name to the diaschismic temperament, comes from [[Hermann von Helmholtz]] much later, in 1875.<ref>[https://yahootuninggroupsultimatebackup.github.io/tuning/topicId_62661#62683 Yahoo! Tuning Groups | ''Diaschisma article'']</ref> The interval [[648/625]], the modern "diminished comma" by virtue of it being the one diminished temperament makes vanish, has been called the "major diesis" or "greater diesis",<ref>[[Wikipedia: Diesis]]</ref> and so "major diesic" was also proposed as a name for this temperament.<ref>[https://yahootuninggroupsultimatebackup.github.io/tuning-math/topicId_2064#2067 Yahoo! Tuning Groups | ''Kleismic & co'']</ref> This would have gone along with [[128/125]] being the "(minor/lesser) diesis" and thus "minor diesic" temperament. Despite this not working out this way (due in part to too many things being named using "diesis"), in the end "diminished" and "augmented" still came out as an opposing pair.   

Meaning: It's meantone which calls the dominant seventh chord a 4:5:6:7. It is one of the least complex 7-limit extensions of meantone.
