     Let's say you took violin lessons all through elementary school, but you haven't got the instrument out

of its case for years. Were all those lessons a waste of your parents' money because you didn't become a

violinist?

     Even though it has been a long time since you played the violin, a new study shows that as little as one

year of music training can have a positive impact (影响) on your brain that will last the rest of your life.

     In an experiment, researchers compared children who had taken music lessons to those who hadn't.

Laurel Trainor, who studies music and the mind, discovered that the musically-trained children had better

brain responses in certain sound recognition exams. Trainor's findings show the possibility that musical

education can actually improve the brain's hearing cortex(大脑皮层). "The study's results show that

music training affects attention and memory, and helps children develop learning skills. In this way music

training might lead to better learning across a number of fields," Trainor said in a statement. The effects

of music education are even more obvious on children with difficulty in reading and writing and other

language-related disabilities.

      So, whether you can play a good piece of music or not, it's likely that your years of music lessons

have prepared your brain for all the speeches, emails, and adult conversations that are part of your life

today. We should help make sure that children today have the same opportunities for music, and help

out by volunteering with or donating instruments to your school's music education department.
