I've been encountering more and more pianos of late that seem = to have a real scaling problem in the low tenor section. Baldwin model 248 = comes to mind; ( the last note in the tenor is C# I believe), but where I = really see it is in the new Yamaha model GA1, and to a lesser extent in the = GH1. What is happening is that the designers of these pianos have put too many = notes in the tenor that belong in the bass. As you play chromatically down = the scale, these notes start sounding like "pong-pong-pong" and then you = hit the bass, and they sound normal again.</FONT></DIV> <DIV><FONT face=Arial size=2>    I know that this = is caused by continuing to drop the tension on the strings in order to get the = fundamental down to the required frequency, but you reach a certain = point, and you get a tone that seems hollow and is very difficult to fit in = with the rest of the tuning.</FONT></DIV> <DIV><FONT face=Arial size=2>    I've had some = partial success with carefully doping the hammers, and voicing the bass = down, plus leveling strings, straightening termination points etc., but not to = any totally satisfactory result. </FONT></DIV> <DIV><FONT face=Arial size=2>    Got any good = advise? I'm all ears.  </FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>    Or is it just = poor design?</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Kevin E.
