<DIV><FONT face=Arial size=2>How DOES one go about teaching how to =
establish
proper key height in an upright? I've heard discussions about =
parameters
as determined by case parts, balance pin height, and so on, that =
doesn't
really home in on the optimum key height.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Recently I came to a fairly new =
delivery where
the customer complained that she couldn't get sufficient =
repetition. Two
other technicians before me had tinkered with the action enough to get =
sufficient aftertouch, but the piano played with all of the grace of a =
heavy
truck. Both technicians had confessed to the customer that they =
were not
pianists, and had done as much as they could according to the =
manufacturer
specs.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Now I'm hardly a pianist myself, but =
my first
sense was that the keys were sitting too low. OK, raised the =
key-height,
and regulated the action accordingly, including adjusting the key =
depth.
Got a nice aftertouch equation and turned the customer loose on =
playing
it. She reported that the action now flies.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>What have I done? Both =
technicians and the
dealer all want to know. I told them what I could, but realized =
that I
had no real way of explaining how to determine what the optimum key =
height
should be for any particular upright piano. The =
original key height
was well within the parameters mentioned above when I first came to =
the piano,
but I knew it could be greatly improved ......</FONT></DIV>
