Now THAT'S an interesting premise. Has anyone out there compared the
theoretical inharmonicity curve from a scaling spreadsheet to the actual
inharmonicity measurements in the same piano? What DOES happen to the real
world curve at the tenor/treble break when going from the agraffe to the
front duplex termination? Does the inharmonicity drop at the start of the
duplex?
