[CAUT] Duplex

So what you're saying is that a less sharp termination allows the string to
pivot and, in effect, influences the stiffness factor of the wire.  I would
think that as long as the situation was stable that the measureable
difference would be small, the audible difference probably insignificant.  A
more rounded or flatter and wider termination also has the potential of
creating an oscillating string length which might have a greater negative
impact, i.e. falseness.  It would be my guess that as long as the
termination was stable, that is not oscillating to the point of falsenss,
that any increase in inharmonicity due to the ability of the string to pivot
would be relatively insignificant, meaning even if you could measure it, in
practice you probably couldn't hear it.  For me, the importance of the shape
is to avoid falseness, leakage and produce long term stability.  These
issues I would rate as much more important than any inaudible differences in
inharmonicity.

David Love asked if I thought a sharp profile at the capo bar, combined
with the duplex, would increase the inharmonicity.  No, I would expect it
to decrease it.  In a later post, Rec Brekne described exactly what I was
talking about.  However, it's difficult to maintain a capo bar radius of
less than 0.5 mm if there is much pressure against it.
