I'm a big fan of music and use it a lot when working, but I had no idea about how it really affects our brains and bodies. Music is such a big part of our lives, and we react to it in many ways without even realizing.
Of course, music affects many different areas of the brain, as you can see in the image below. We're only scratching the surface with this post, but let's jump in.
Happy/Sad Music Affects How We See Neutral Faces
We can usually pick if a piece of music is particularly happy or sad, but this isn't just a subjective idea that comes from how it makes us feel. In fact, our brains actually respond differently to happy and sad music.
Even short pieces of happy or sad music can affect us.
One study showed that after hearing a short piece of music, participants were more likely to interpret a neutral expression as happy or sad, to match the tone of the music they heard. This also happened with other facial expressions, but was most notable for those that were close to neutral.
Something else that's really interesting about how our emotions are affected by music is that there are two kind of emotions related to music:
perceived emotions and
felt emotions. This means that sometimes we can understand the emotions of a piece of music
without actually feeling them, which explains why some of us find listening to sad music enjoyable, rather than depressing. Unlike in real life situations, we don't feel any real threat or danger when listening to music, so we can
perceive the related emotions without truly feeling them—almost like vicarious emotions.
Ambient Noise Can Improve Creativity
We all like to pump up the tunes when we're powering through our to-do lists, right? But when it comes to creative work, loud music may not be the best option.
It turns out that a
moderate noise level is the sweet spot for
creativity. Even more than low noise levels, ambient noise apparently gets our creative juices flowing, and doesn't put us off the way high levels of noise do. The way this works is that moderate noise levels increase processing difficulty which promotes abstract processing, leading to higher creativity. In other words, when we struggle (just enough) to process things as we normally would, we resort to more creative approaches.
In high noise levels, however, our creative thinking is impaired because we're overwhelmed and struggle to process information efficiently.
Our Music Choices Can Predict Our Personality
In a
study of couples who spent time getting to know each other, looking at each other's top ten favorite songs actually provided fairly reliable predictions as to the listener's personality traits. The study used five personality traits for the test: openness to experience, extraversion, agreeableness, conscientiousness and emotional stability.
Interestingly, some traits were more accurately predicted based on the person's listening habits than others. For instance, openness to experience, extraversion and emotional stability were the easiest to guess correctly. Conscientiousness, on the other hand, wasn't obvious based on musical taste.
Here is the break-down of how the different genres correspond to our personality, according to a study conducted at Heriot-Watt University:
- Blues fans have high self-esteem, are creative, outgoing, gentle, and at ease
- Jazz fans have high self-esteem, are creative, outgoing, and at ease
- Classical music fans have high self-esteem, are creative, introverts, and at ease
- Rap fans have high self-esteem and are outgoing
- Opera fans have high self-esteem, are creative, and gentle
- Country and western fans are hardworking and outgoing
- Reggae fans have high self-esteem, are creative, not hardworking, outgoing, gentle, and at ease
- Dance fans are creative and outgoing but not gentle
- Indie fans have low self-esteem, are creative, not hard working, and not gentle
- Bollywood fans are creative and outgoing
- Rock/heavy metal fans have low self-esteem, are creative, not hard-working, not outgoing, gentle, and at ease
- Chart pop fans have high self-esteem, are hardworking, outgoing, and gentle, but are not creative and not at ease
- Soul fans have high self-esteem, are creative, outgoing, gentle, and at ease
Music Training Can Significantly Improve Motor and Reasoning Skills
We generally assume that learning a musical instrument can be beneficial for kids, but it's actually useful in more ways than we might expect.
One study showed that children who had three years or more musical instrument training performed better than those who didn't learn an instrument in auditory discrimination abilities and fine motor skills.
They also tested better on vocabulary and nonverbal reasoning skills, which involve understanding and analyzing visual information, such as identifying relationships, similarities and differences between shapes and patterns. These two areas in particular are quite removed from musical training as we imagine it, so it's fascinating to see how learning to play an instrument can help kids develop such a wide variety of important skills.
Classical Music Can Improve Visual Attention
It's not just kids that can benefit from musical training or exposure. Stroke patients in one small study showed
improved visual attention while listening to classical music.
The study also tried white noise and silence to compare the results, and found that, like the driving study mentioned earlier, silence resulted in the worst scores. Because this study was so small, the conclusions need to be explored further for validation, but I find it really interesting how
music and noise can affect our other senses and abilities—in this case, vision.
Music Helps Us Exercise
Research on the effects of music during exercise has been done for years. In 1911, an American researcher, Leonard Ayres, found that cyclists pedaled faster while listening to music than they did in silence.
This happens because listening to
music can drown out our brain's cries of fatigue. As our body realizes we're tired and wants to stop exercising, it sends signals to the brain to stop for a break. Listening to music competes for our brain's attention, and can help us to override those signals of fatigue, though this is mostly beneficial for low- and moderate-intensity exercise.
During high-intensity exercise, music isn't as powerful at pulling our brain's attention away from the pain of the workout.
