When visiting the Petrof Piano Factory last year at the EuroTech  
conference, new grands had ebony caps in the high treble on their pianos as  well.

To what effect? I have a whole pile  of ebony veneers left over from  
other projects and have often  wondered how they would work as a bridge  
cap. Or maybe even making a  laminated hard maple cap with an ebony  
lamination as a topper. I  guess I've thought that hard, harder and  
even harder is good for a  bridge cap, but is there some point where  
the cap can get too  hard?
