At present the Vienna Symphony uses A444. When this piano was built pitchs around A453 were floating around.

What kind of complications are you refering too ? I think the idea behind that is that starting at one end and going to the other increases the tension from left to right (or right to left) which is supposed to be more predictable then starting in the middle, going up, and then going down... or around and around as it were. I also think there some room for discussion about the validity of the idea, and eventually just what is stretching what and how :)... usually is with these things. > (I read this in the TuneLab documentation). > Wouldn't you want to make the biggest tension adjustments first, and the > least last? > > --Cy Shuster-- > Rochester, MN > > Cheers RicB
