<html> <head> </head> <body> <DIV>IMHO Meantone means 1/4 comma. This is the one that gives pure 3rds.  There are other "meantones" such as 1/6 but the one in general use historically was 1/4th comma.   Since they can all be tuned by machine you might want to check with someone to see what was actually being used.  But Groves is the authority* and the article Temperament is where all the info is. There is a whole section on Meantone.  Comma is explained there and I believe there is a seperate article on comma as well.       R Moody </DIV> <BLOCKQUOTE style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px">> >   > > A harpsichord here at BYU is supposed to be kept in meantone, but I'm > not sure which one.
