Diane: Did you try to move the piano to another position to see if there was a change? Are there ceiling fans? If what you call "false beats" are actually "real beats", i.e. real frequency interference, then the issue resides somewhere in the mass/tension/length string systems of the piano itself. Did you settle the strings carefully on the bridges? Concrete floors are an unlikely "cause". I also doubt that the bricks are "absorbent", quite the reverse. As the mathematician Richard Feynman asked, "Does a brick have an inside?"

It sounds terribly reverberant.? ? ?I had to prep an Estonia 9' for a music teachers' recital last weekend.? Octaves 5 and 6 had fast, fluttering false beats, and little power.?The long side of the piano was along one of the brick walls.? Do you think the concrete floor could be causing the false beating, and the bricks absorbing some of the treble brilliance? ? The 6' Estonia about 20' away, approximately in the center of the room, sounded like the bigger, richer piano.?I didn't tune it, so don't know about false beats. ? ?
