　　Scientists long have wondered whether we are born with our musical tastes. A team of researchers wanted to find out the answer. Team leader Josh McDermott is a scientist at the Massachusetts Institute of Technology in Cambridge.

McDermott's team worked with five groups of adults. Two of the groups live in the United States. They listen to Western music. People in one of the two groups had each played a musical instrument for an average of 7.7 years. Those in the other group had played music for less than a year. This allowed the researchers to study whether playing an instrument changed the kinds of sounds people like to hear.
