<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>
