"which may point to the curvature of the bearing points as a partial (no pun intended) cause of inharmonicity changes.? Ken, Almost. Termination will effect tone and duration but inh. very little. Curvature AT the termination is the causative effect of inh. Nodal points do not cause inh. since they are essentially points without dimension. The real culprit is the stiffness of the wire. Thicker wire and/or higher tension will increase inh. Wire is not hinged at the terminal points, hence the wire begins to flex at some point away from the terminal point, thereby shortening the effective length of the string. Partials have progressively less energy to flex the wire so the end points are further from the terminations. Higher partials have higher inh. Relatively simple concepts but it sure took a long time to understand. Newton
