<DIV><SPAN class=078335403-14012008><FONT face=Arial color=#0000ff size=2>BUT...
As I understand it, one of the important reasons for the X and Y axis to
terminate at exactly the same point, (at the bridge), is that if one axis
is different than the other then the string is essentially a different length in
one axis than the other. This increases inharmonicity and causes
conflicting partials in the two axis. This is a similar reason as to why
the windings on bass strings must be the same length and end at the same
distance from BOTH termination points. I understand that, among other
things, equal termination at the bridge equates to maximum transfer of
energy to the soundboard, but doesn't unequal termination at the agraffe or capo
bar cause distortion in the string waveform that not only increases
inharmonicity and unwanted conflicting partials but also a loss in overall
energy?</FONT></SPAN></DIV>

don't mean to start an argument. I'm really just interested in the mechanical
logic of this centuries old manufacturing practice. For all I know the
contribution of any errors at the agraffe or capo bar may be so insignificant as
to be unworthy of consideration. I'm just curious. </FONT></SPAN></DIV>

<DIV>As Annie indicated, the string needs to go over the bridge for the
vibrations to transfer from the string to the soundboard. The string needs to
be seated at both sides of the bridge, so that the vibration is
transferred without interference. If the string is not seated, then there
will not be a solid transfer of the vibrating string. <BR><BR>See what
happens when you start thinking. <IMG height=19 alt=:

<DIV><FONT face=Arial size=2><SPAN class=343043301-14012008>I made the mistake
of thinking the other day, and I started wondering why piano strings are
terminated at the bridge on both the X and Y axis but at the capo bar, or
agraffe, on only the X, (or perhaps that's Y depending on how you are
looking at it), axis. We go to lengths to make sure the strings are seated
properly at the bridge so that there is a definite and precise termination in
both planes at the bridge and bridge pin. Why then is the lack of
termination in both planes not a problem at the agraffe and capo bar end?
