Interesting! I used to have a Baldwin Acrosonic, a spinett with a painfully bright tone. I placed a 4-inch- thick piece of foam rubber between the back of the piano and the wall. When I played a 1930 Baldwin Grand in a nursing home, which sat on a hardwood floor in a room with acoustically hard walls, I placed a few blankets on the floor below the piano, and even placed a comforter inside the lid, making sure that it didn't touch the strings. Now I have a new Steinway B in my house (so I'm in piano heaven), and the room is only 22 by 11 feet, so the piano really is much too big for the room. I'll certainly try that styrofoam insert that you demonstrated.

Thank for the tips.
