Since inharmonicity (to my understanding) is the inability of the rigid string to bend at EXACT fractions, it stands to reason that the only true harmonic could be produced by a string of zero width, because there will ALWAYS be some degree of inflexibility in any string of any dimension. <div>On Sun, 04 Feb 2007 08:49:13, Don <<a href="mailto:pianotuna@accesscomm.ca">pianotuna@accesscomm.ca</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hi Robert, Correct about organs and inharmonicity--incorrect about violins. I was very curious a few years ago and took some careful measurements on my fiddle while I was playing. No matter how gently I bowed there was some inharmonicity.
