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.

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. Jim Ellis
