Yes, here I is.

I'm too lazy to do the math, but 1/16 inch in four feet might be a radius of
what?  a couple of hundred feet?

Now, having an arc? (part of circle) in a keybed will give more SOUND?  I
sure wouldn't have thought so.  Maybe we don't need crown in the soundboard
after all, just put lots of crown in the key bed.  If Steinway does it, it
can't be all bad, now, can it?
