钢琴课有助于提高语言表达能力。据说音乐家拥有较好的语言表达能力。而科学研究也证实了这一理论，不过对于音乐为何会激发语言能力，这一点还不清楚。

Musicians are said to have better language skills. And scientific studies have backed that up. But it's not clear why that might be the case.

Now a study of 74 Chinese kindergartners suggests six months of piano lessons can heighten the brain's response to changes in pitch. And kids who got piano lessons were also better at telling apart two similar-sounding Mandarin words, which contained different consonants, than were students who got extra reading training, or who went through regular kindergarten.

The results are in the Proceedings of the National Academy of Sciences.

Now Mandarin is a tonal language - the famous example is the word 'ma' which can mean mother or horse depending on its pitch. So might musical training translate better to Mandarin, than it would to English?

Yeah it's possible that influenced the results. Robert Desimone, a neuroscientist at the McGovern Institute at MIT. But he says other studies do back up the fact that music lessons benefit language learners, even in countries without tonal languages. "And what our study added on top of that was some idea of the neural basis for those benefits."

And if you don't own a piano, don't despair. The reading group actually did just as good on many measures as the piano group. "Reading's pretty good actually. We don't mean to downplay reading instruction."

More important, he says, was to show piano wasn't actually worse than reading for these skills... perhaps encouraging cash-strapped schools to keep their music programs alive.
