I know that is the generally regarded as reason for the crown in the 
keyboard. But if that were the case, all keyboards that were not crowned 
would be sagging. And I just don't see that in enough pianos to believe the 
story.  Furthermore, I see a crown in 50 - 75 year old Steinways. When is it 
supposed to flatten out?

There's got to be another reason. Anyone?
