<DIV> Joe stated that: > > Inharmonicity works in relation to tension. If the > > tension goes up, so does Inharmonicity I was simply stating that increasing tension on a wire actually lowers its inharmonicity. 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!!!!!
