| Violin prodigies, I learned, have come
in distinct waves from distinct regions. Most of the great performers in the
late 19th and early 20th centuries were born and brought up in Russia and
Eastern Europe, I asked Isaac Stern, one of the world’s greatest violinists the
reason for this phenomenon. "It is very clear," he told me, "They were all Jews
(犹太人) and Jews at the time were severely oppressed and ill-treated in that part
of the world. They were not allowed into the professional fields, but they were
allowed to achieve excellence on a concert stage." As a result, every Jewish
parent’s dream was to have a child in the music school because it was a passport
to the West. Another element in the emergence of prodigies, I found, is a society that values excellence in a certain field to nurture (培育) talent.
