<DIV><FONT face=Arial size=2> Here's my =
speil: I explain
to the customer that beyond certain limits, the strings need to be =
brought
up to the proper tune in stages, rather than all at once. The =
reason
is that the strings have not seen this much tension in a long time =
and
bringing them up to the correct pitch too far all at once will =
result in
the strings stretching (a normal reaction) and the tune going flat
immediately. For that reason the first tuning (pitch raise) =
involves
tuning each string slightly higher than the final result to take =
advantage of
this drop in tone. This is called overpull. By the =
time the
second pass is made to fine tune the piano, the strings will have =
settled
and fallen back close to where they should be for the final =
tuning.
</FONT></DIV>
<DIV><FONT face=Arial size=2> With this in mind, =
if we tune
only up to the proper pitch once and not beyond, the strings will =
stretch and
the piano will be flat when finished. I explain that I =
wouldn't get
out of their driveway before sour notes would be heard. =
</FONT></DIV>
<DIV><FONT face=Arial size=2> I find it helpful to =
show the
customer on my Korg tuner I use for pitch raising, the needle and =
scale
and the relationship of all these elements. =
Drawing a
picture may be helpful also. </FONT></DIV>
