Matt Haimovitz is 42 and a renowned cellist (大提琴手) in the world. He rushed into the classical music scene at the age of 12 after Itzhak Perlman, the famed violinist, heard him play.

But nothing in his family history explains where Haimovitz got his extraordinary talent. And that’s typical, Ellen Winner, a professor says.

“People are fascinated by these children because they don’t understand where their talent came from. You will see parents who say, ‘I wasn’t like this, and my husband wasn’t like this.’ It seems to sometimes just come out of the blue,” Winner says.

It’s not clear whether a prodigy’s (天才)brain is any different from the brains of other children, in part because there have been no study comparing the brains of prodigies to those of average people.

“But I believe that anything that shows up so early, without training, has got to be either a genetic or some other biological basis,” Winner says. “If a child suddenly at the age of 3 goes to the piano and picks out a tune and does it beautifully, that has to be because that child has a different brain.”

Children who are extremely gifted tend to be socially different, too, Winner says. “They feel like they can’t find other kids like themselves, so they feel strange, maybe even like a freak, and feel like they don’t have anybody to connect with. On the other hand, they also long to connect with other kids, and they can’t find other kids like themselves.”

As Haimovitz got older, he became frustrated. He wanted to play other kinds of music but felt constricted by the image and the expectations of the boy prodigy who played classical music and filled concert halls.

“When you start that early, you suddenly start to grow up in public, and I wanted to experiment,” Haimovitz says.

So he took his cello into punk rock clubs and coffee houses. He played Bach, Haydn and Hendrix. “My teacher was Leonard Rose, and we never played any 20th-century music. He didn’t like it. But once I was exposed to James Marshall “Jimi” Hendrix, Miles Dewey Davis El and others, I couldn’t really turn back. I wanted to know more,” he says.
