Of course, if you raise the tension of a particular = note by increasing the wire size you will get a net gain of inharmonicity, but = this is due to the greater stiffness of the thicker wire, not the = greater tension. > > ----- Original Message ----- = > From: "ryan sowers" <pianorye@yahoo.com> > To: = "Pianotech" <pianotech@ptg.org> > Sent: Thursday, August 05, 2004 = 4:30 PM > Subject: Re: Rescaling questions > > > = > Inharmonicity goes down with increased tension, > all > = > other things being equal. > > > > --- Joe Garrett <joegarrett@earthlink.net> wrote: > > > Squuuuuuzzzzzz me!!!!!
