Eight New Things We’ve Learned About Music

From The Smithsonian:

Why is it that music can affect us in such profound ways? “Because it does” seems like a pretty good answer to me, but scientists aren’t that easy. They’ve been wrestling with this for a long time, yet it was not that long ago that two researchers at McGill University in Montreal, Anne Blood and Robert Zatorre, came up with an explanation, at least a physiological one.

The truth is we’re learning new things about music all the time. Here are eight studies published in just the past few months.

1) But can you dance to it?: Toronto researcher Valorie Salimpoor wanted to know if our strong emotional response to a song we like is due to the music itself or some personal attachment we have to it. So she had a group of people listen to 30-second samples of songs they’d never heard before, then asked them how much they’d be willing to pay for each track. And she did MRI scans of their brains while they listened. The result? When the nucleus accumbens region became active–it’s a part of the brain associated with pleasant surprises or what neuroscientists call “positive prediction errors”–they were more willing to spend money. In other words, if a song turned out better than they had expected, based on pattern recognition, they wanted more of it.

2) Drum solos not included: Two McGill University psychologists in Montreal say that soothing music can actually be more effective than Valium when it comes to relaxing people before surgery.

3) Unless their favorite song is by Metallica: And it helps even the tiniest of babies. A study at Beth Israel Medical Center in New York found that when parents turned their favorite songs into lullabies and sang or played them on an instrument, it reduced stress levels in the infants and stabilized their vital signs.
