Ole Bull, the Norwegian violinist from the last century, studied under good teachers but not excellent ones.
He was so gifted that when he was 25, he landed a European Tour. Arrived in Milan, a critic, after attending his concert wrote:
– It is a musician who lacks training. Sure he is a diamond, however, for now he does not measure up to it.
Reading this article, the blow struck home.
He got up, went to the newspaper headquarters and asked to speak to the journalist. He was a musicologist of 70 years – who knew what he was talking about –
Ole Bull listened in minute details everything that this man had to say about his technique, his mistakes and everything he could still improve.
The next day, he called off what was left of his Tour, went back home, changed teacher and worked on his technique for six months.
He then resumed his concerts and experienced an unprecedented success all his life.”
