I had a teacher once who called his students “idiots” when they screwed up. He was our orchestra conductor, a fierce Ukrainian immigrant named Jerry Kupchynsky, and when someone played out of tune, he would stop the entire group to yell, “Who eez deaf in first violins!?” He made us rehearse until our fingers almost bled. He corrected our wayward hands and arms by poking at us with a pencil.
Today, he’d be fired. But when he died a few years ago, he was celebrated: Forty years’ worth of former students and colleagues flew back to my New Jersey hometown from every corner of the country, old instruments in tow, to play a concert in his memory. I was among them, toting my long-neglected viola. When the curtain rose on our concert that day, we had formed a symphony orchestra the size of the New York Philharmonic.
I was stunned by the outpouring for the gruff old teacher we knew as Mr. K. But I was equally struck by the success of his former students. Some were musicians, but most had distinguished themselves in other fields, like law, academia and medicine.
