<DIV><FONT face=Arial size=2>Hello,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'm a professional pianist and I own a =
Bechstein
grand piano model B (203 cm) dating 1988 (one of the last with ivory =
keys). I
have a question about proper bedding procedure for this =
piano.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The main concern is about bedding it =
with keys and
action installed or without them using the paper method under the
bolts.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>In the first case should I tighten =
the cheeks
screws? And in what order should I regulate the bolts?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Should the keyframe of this piano be =
considered
rigid or flexible?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The 2 procedures give very different =
results,
expecially in the middle registers. What bothers me a lot is checking =
key height
after bedding. It should be 63 mm (that's what Bechstein told me), and =
this is
correct on the left and right side, but if I do the bedding with action =
and keys
installed I obtain a much lower key height in correspondance of the 3 =
middle
bolts. Could the keyframe have bended in the balance rail over time (in =
case it
is a rigid kind)?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Is a bedding procedure based =
exclusively on "sound
quality" be imagined?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I notice a lack of power/precision with =
the
(lighter) bedding done with action and keys installed. Also playing =
gives a
feeling of keys sticking to fingers.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>How does a correct key =
height influence sound
quality and pianist feeling?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I would greatly appreciate any help =
coming from
those with experience on Bechstein grands.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thank you very much,</FONT></DIV>
