Hi Stéphane Why yes, of course we want to look at the overall amount of inharmonicity in re-scaling. My point was that once you settle on a standard to use for calculating... then that becomes your <<reference>>. Any reference (within reason of course) can be used to evaluate both note to note inharmonicities and overall levels yes ? Now of course if you run into a formula for Inharmonicity that doesnt even come close to representing real levels then you have a problem ... :) But anything reasonably close to real inharmonicity levels should serve the purpose well... as long as you remain consistant in your usage of it. I'm not sure about a link between inharmonicity and projection... tho I havent really thought about it that way. Usually I associate projection with loudness/power which is more a function of tension I think.... I'm relatively new at all this so I am sure others will pipe in with needed corrections. Yes ?? Cheers RicB 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). Regards Stéphane Collin
