Michael,

I would sure like to see your future book that tells us how to correctly arch and thickness a violin. That would be a great leap forward for all of us.

thought it over.

And?

I'm just curious.
I've read your posts for many years, John. And I often wonder if you're trying to get violins to fit a particular scheme that you've already accepted as ...

"If that's where you want to be making, where the money is, and that is indeed where the money is, tuning--forcing a violin to vibrate only in certain ways--is one of the various things that ...

I hope all the content is not permanently lost. That would be too bad.

I emailed Jeffrey Holmes. If I hear from him, I will post here.

John,

I am not ready to worry about the Harris formula. I am still trying to either support, or debunk, your formula. I expect to be getting 20 important data points in the next couple of weeks. Th ...

William,
