Violins? Okay, here's some of my story:

For a while, wanting to learn well the math for theoretical physics, I was a math grad student at Indiana University. They put me in courses beneath me and courses irrelevant to the math I wanted. For "beneath", they put me in a course in point-set topology. Maybe okay: First lecture I learned that the text was Kelley, General Topology. Heck, as an undergraduate I'd already gotten a copy and a reading course, read the thing, and gave lectures once a week to a prof. One week I explained a chapter and the next week worked exercises from that chapter. Another course was abstract algebra from Herstein's book. Gads: Group, rings, fields, vector spaces, and I'd had that as a ugrad. I asked the prof if he was going to cover group representations, and he said that was "deep". I told him it was also my ugrad honors paper. Really bad was early in a course in real analysis where the prof wanted to see me after class about my work on his first test. He treated me with contempt. The test had been on set theory, and I'd used lower case omega for the first uncountable ordinal, believed that the notation was standard (had had a summer NSF course in axiomatic set theory), was in a hurry and didn't explain the notation. So I explained. Then the prof caught on: My work was correct and, indeed, one step shorter than his solution. I asked what he wanted to see me about, and he said "nothing". Gads. I didn't want to see him again. They said Galois theory to me one too many times. So, I kept doing my teaching, mostly calculus. Gads, that was first year college calculus, and I'd never taken it but taught it to myself and started on sophomore calculus.

Then I started studying Fleming, Functions of Several Variables with the exterior algebra at the back, etc.

I liked music a LOT, still do, but didn't know much, but Indiana University had a terrific music school, and my dorm was next door. In the dorm was a violin student of Josef Gingold and a protege of Issac Stern with a letter of recommendation from from Zeno Francescatti.

Once, for fun, in a practice room, with a pianist and me listening, he sight read the Vieuxtemps Fifth violin concerto.

One afternoon in the dorm, he put his old Italian violin under my left chin and gave me a first lesson. Magic! So, I signed up for a first course, one on one, in violin! The teacher was another violin student: Poor guy, had to start out by showing me how to hold the violin, and after the semester he was soloist for the Brahms concerto in Toronto! He was good!

Eventually I made some progress: Problems: Started too late, too little talent and practice! But, violin is doable and about the most fun can have standing up -- get a voice to permit screaming out to the heavens about the passion of the human spirit!

On violins, one difference is how easy it is for the violinist to get the sound they want. That's a biggie. A listener may never know about any of that, but there's little doubt for the violinist!

Years later that violin student was a well known professional violinist. I called him for a recommendation of a violin shop for routine maintenance on my violin, and he gave me David Segal Violins in NYC who had made his then favorite violin. IIRC he said he liked the Segal violin better than any of the old Italian instruments.

So, maybe, one way and another, there are people now who know how to make some of the best violins ever.

Generally I long since gave up on taking seriously anything in the NYT. But, gee, maybe for anything they publish, someone likes it!

My favorite piece of music is the Bach Chaconne for unaccompanied violin. I made some progress with it. To me the best part is the end of the central D major section; it has a violin scream out passion beyond belief. The piece deserves more than a solo violin and has been arranged for solo piano by Busoni and also for full orchestra. A piano performance I like is

When my startup is farther along, maybe I'll get some maintenance on my violin and get through the rest of the Chaconne. Just need a lot of practice!
