I see nothing disproved. The coupled motion thing seems to be an issue of semantics as well as the para inharmonicity. I also disagree with the statement that tuning devices have shortcomings, They are just measuring devices and if there is a sound there, it measures it. How the data is interpreted and used by the operator is where the shortcomings are. You know, a man can be a 5 time divorcee loser or a man who is not afraid to make a commitment. Depends on how you word it. </div> <div>   </div> <div> Keith Roberts   </div> <div> On 6/10/07, Remoody <<a href="mailto:remoody@midstatesd.net">remoody@midstatesd.net</a>> wrote: <div> Was posted........

"Para inharmonicity" is a myth to explain (or excuse) the short commings of tuning machines.  Inharmonicity seems to be a valid scientific phenonenom but still eludes consistant measurement. --Richard Moody   </div> </div>   </div> </body> </html>
