A newly added question had the tag "temperament" added in connection with violoncello and upon finding an impressive amount of text in the tag description, I conclude that it claims to cover concert-pitch issues ("frequency to tone assignments").
I would have expected, that "temperament" is only applicable to instruments to be subjected to different temperaments (as mean-tone, Werckmeister etc.), so continous-pitch instruments as cello would not qualify...
This viewpoint is somewhat supported by English Wikipedia:
Temperament, in music, the accommodation or adjustment of the imperfect sounds by transferring a part of their defects to the more perfect ones, in order to remedy, in some degree, the false intervals of those instruments, the sounds of which are fixed; as the organ, harpsichord, piano-forte, etc.
Is this agreed or was a concert-pitch tag already discussed?
