I've always thought that the more widely a belief is held the more apt = is to be false. Could that be true of crowned boards? If reverse crown = sounds good, would you design and build me a reverse crowned board that = I could put in my style 2 S&S grand? I'm only partly kidding. Purposely putting in a reverse crowned board = is another one of the weird things I might try. Regards Carl Meyer Assoc.

It is one of those things that is just too intentional and = symmetrical to simply be a collapsed board. I have yet to run across one = that didn't sound more musical than most pianos ever dreamed of being. = Julius Bauer, Becker Bros. ,Steck and others I can't recall the names of = right now. The boards were also not split up from the tension instead of = compression as one might think.

The more interesting thing was = that the board was a reverse crowned board with a positive set = downbearing. I mean bearing set pressing in the usual direction.

I keep = finding all kinds of sound board conditions and configurations which = aren't supposed to work that do and others that should that don't!=20 I have to figure that the weight of the Big Brass agraffes also = contributed to the impedance properties of the board probably a sustain = enhancing dynamic.
