I spent a decade studying sound and working in pro audio, and have a high-level physicist for a son that I discuss sound-related subjects with frequently.
What you claim is nothing more than the violin version of ghosts and haunted houses. Absolute and utter horseshit in real world physical terms, and nothing but auditory placebo effect in psychological terms. When True Believers want a certain sensory input bad enough, their brains will manufacture it.
I'm so awed by that I can hardly respond. But I'll try anyway.
I've played those instruments. And worked on them. I'm as familiar with them as you are with pipes. And at a high enough level of accomplishment that a place you've probably heard of gave me a free ride for a MFA to have me playing there for two years. After I tired of the symphony jobs.
What you're saying is that if you can't measure something with your little gadgets, it doesn't
and cannot exist. And for proof you point to the instruments themselves. Circular reasoning much ?
200 years of collective experience at the highest levels of accomplishment in complete agreement are as nothing to someone who imagines that he can reduce everything to abstractions and then manipulate them to paint the picture he likes. That's the Enlightenment syndrome. It's faith in empiricism. 100%. And it doesn't pan out.
In the mean time, in an age when people desperately need great instruments, the almost unheard-of top price for the finest new one runs around $150K (with a heavy famous guy association. Otherwise, about $60K).
While a fine Strad or Guarneri regularly tops 10 Million.
Because the most accomplished violinists alive -- collectively -- are all idiots who have no idea what they're doing.
