I really do believe that playing a string instrument raises ones IQ. In fact, a 3-year study in Switzerland looked at 1,200 children, and found they actually learn faster, when they had more music classes. The kids who were given the extra music classes, were actually better at language, and as good at maths, as the other kids - even though they had had fewer language and maths classes. The music class kids were also better in retelling stories that had been read to them - whether they wrote it in words, or drew it in pictures. And the kids that had the extra music classes also were quicker at learning how to read.
Yet another study showed that playing the violin, can make your brain grow bigger. When you're playing the violin, your bow arm (the right arm) provides intricate balance and precision, as it moves the bow back and forth over the strings. But the fingers of your violin hand (the right hand) have a very hard task. They have to press exactly on the right spot on the right strings, for exactly the right amount of time, and do this all, very accurately, and often, very rapidly.
This study found that the part of the brain that controls the fingers of the left hand, (which is usually the weaker hand) is actually bigger in violin students, as compared to everybody else.
