(Finally something I can contribute to, on HN)

My father plays in a baroque orchestra (the Amsterdam Baroque Orchestra), and I know that when they play a repertory, e.g. Dieterich Buxtehude, the orchestra tunes to 465 meantone.

I suspect the temperament makes a dramatically larger difference than shifting every note sharper by a bit less than (95.7% on a log scale) a semitone compared to A440.
