This is Scientific American's 60-Second Science, I am Steve Mirsky,Got a minute?

A team of Finnish and American geneticists has found that that, for some people at least, music is in their genes1. In what the researchers called the first study of its kind, they found specific regions of chromosomes2 that were connected to musical ability. The report appeared in the Journal of Medical Genetics. The subjects were 234 members of several generations of 15 families in Finland. The team used a number of tests to gauge3 musical skill: one measured pitch, another tested the ability to keep a beat. The chromosomal4 regions that were found to be connected to music are known to be involved in the migration5 of neurons during development. And the study also found that the musical DNA6 overlapped7 with a region associated with dyslexia. That finding suggests that language and music have a common evolutionary8 background. Of course you’re going to need more than the right genes to make you a good musician. Because while the N and R trains will take you there, the best way to get to Carnegie Hall remains9 practice.

 hanks for the minute for Scientific American's 60-Second Science, and I'm Steve Mirsky.
