Scientists have discovered the first evidence that playing an instrument can increase the brain and sharpen the hearing for all kinds of sounds, including speech. "Music seems to help a lot more in life, transferring activity to reading or catching nuances in voices or hearing certain things in a gallant class," says Nina Kraus, a neuroscientist at Northwestern University. The researcher is of the opinion that these conclusions shed another light on the importance of school music hours. The researchers' experiment was initially performed on 20 volunteers. Half of the participants had at least 6 years of musical experience with a certain instrument, classes starting at the age of 12 years.
The other participants had no more than 3 years of musical experience. While watching a movie of their choice, the volunteers also heard some words in Mandarin. Those with greater musical experience distinguished all 3 different tones from the words in mandarin. The researchers say, however, that these effects have been encountered in other people, not being a top musician to observe the different tones. Scientists have also found that these changes occur in one part of the brain, responsible for automatic control, which "deals" with heartbeat and breathing.
