> A WT or meantone can fit a broad-ranged description. > It can have any number of "errors" in it and still function and be a WT or MT. > It's only "equal" if it is. ------------- Meaning no disrespect, then it's only Werckmeister III if it is. I think there's a "modulation" in the logic here. Pretend for a moment that we have decided that the ideal temperament crucial to a particular musical program or piece is the Valotti/Young. If an ET with a couple of half-cent errors is still a temperament, but no longer functions as ET; then, is a Valotti/Young with a couple of half-cent errors still a temperament but no longer recognizable as Valotti-Young? When does the concept of Just Noticeable Difference [I like it -- is that yours, Ed Foote?] come into play for a SPECIFIC well-temperament? If we are going to complain about inaccuracies in one temperament, don't we have to hold all temperaments to the same standard? If a Valotti/Young is not perfectly accurate but can still function satisfactorily, so can an ET with the same level of error, I think. Bob Davis
