Do you play a musical instrument? If so, you may be getting smarter. A recent study shows that taking music lessons can raise a person’s IQ.

Scientists studied 132 children in Canadian schools. At the beginning of the school year, these children took an IQ test. Then they were divided into four groups. One group took singing lessons. Another group took weekly piano lessons. The third group took classes in drams(戏剧). And the last group did no special activities at all.

At the end of the school year, the 132 children took an IQ test again. In all four groups, the average score went up. However, the piano players’IQs went up 7.0 points on average. The average increase for the other three groups was only 4.3 points.

The researchers say that the difference is small and it may not result in better grades for the piano players. However, they still consider the results important. Learning an instrument helps kids becomes better at concentrating and at memorizing things. Therefore, the researchers say, it may be good for brain development in young people.

If you have a chance to learn to play a musical instrument, never miss it. Remember it can make you smarter.
