Hi Ric. While evenness of inharmonicity seems indeed obviously desirable, don't we want to be able to evaluate the overall inharmonicity of a piano ? I mean you can desing a scale that will be even in inharmonicity, but whose overall inharmonicity is so high that the piano sounds funny, same (but less probable) for a piano with too low inharmonicity. Isn't there a link between overall inharmonicity and "projection" (ability of the piano to fill a space with it's sound) ? There is certainly a link between overall inharmonicity and personnality (sorry for that vague and subjective word).
