Thanks for the info. We have 2x10 16oc joists. I was figuring that we
would need a backer board. Of course, we don't want to have to do the
whole area with the backer board.

It would be a standard practice to do the whole area with backerboard, if
you don't do a wet bed.

And definitely use porcelain tiles, like the other comment suggests.


Would it be feasible to put the
backer board only in the general area where the piano would be? Using a
thinner underlayment so that the 'base' flooring would be the same
thickness?

As for acoustics, tile and other hard flooring just make the room more
acoustically 'live'. This can be countered with curtain and other wall
coverings.
