Thank you Jason, this is just what I needed to know.The link to the web-site was helpfull too,but a little confusing.The piano we will be using is one that is moved to 442 sometimes so it is used to being stretched out and back,so I think I will keep the original offsets.(that way I don't have to do any math) Robin Olson -------------- Original message ---------------------- From: "Jason Kanter" <jkanter at rollingball.com> > What you want is the Romieu 1/7 comma meantone.
