Ramsey=20 To: pianotech@ptg.org=20 Sent: May 18, 2001 7:23 PM Subject: Scaling problem I've noticed something on some newer pianos lately, and decided to = ask the opinion of the sages on the list. 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. 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. 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.=20 Got any good advise? I'm all ears. =20 Or is it just poor design? -------------------------------------------------------------------------= ----- Yes.
