<DIV><FONT face=Arial size=2>One of the problems I have been trying to solve is
how to improve my unisons so that they stay in tune longer and don't go out
shortly after I have tuned the piano. I apply firm test blows to equalize the
tension along the string, but find that the some of the unisons
in the treble still go out of tune within a few days or weeks afterwards. I
think the problem is due to not setting the pin properly. The question I have
is, during unison tuning, and when you are tuning each outer string to the
center string, do you turn the tuning lever to raise the pitch to the high
side of the center string, to the point that you hear a "tinny sound" when the
two frequencies are different, and then turn the tuning lever to bring the pitch
back down so that it sounds pure? I read somewhere that the amount the
strings should be raised before bringing it down is to the point that you can
hear a beat of a few Hz, but raising the pitch to the point where you hear
a tinny sound is more than a few Hz. Thank you for your advice. </FONT></DIV>
