Music on the Brain
Monday, February 14th, 2011Have you ever wondered how some musicians are able to craft emotionally rich lyrics and pair them with emotionally moving music so perfectly? (Music is the language of pure emotion, after all.) Yes, it is an art that takes some time to perfect; but there’s also a physiological explanation, or at least a partial explanation. Musicians are more in-tune with human emotions than non-musicians. Studying music (crafting music, not just listening) gives people an advantage over non-musicians in detecting emotional changes through faint changes in tone and pitch that are missed by non-musicians. Musical training involves listening for patterns and nuances in music and knowing how adding something will alter the musical (and emotional) integrity of the whole, and musicians’ nervous systems are better able to identify and utilize relevant patterns in music and speech alike.
Not only that, but musicians are more easily able to filter out background noise to focus on a human voice, meaning that they’re doubly better at detecting emotion in, say, a crowded bar or restaurant. Musical training also involves picking your notes out from all of the others that are played, and identifying which notes are most relevant to yours.
Why is this? Studying music actually re-wires the brain to be this way. It makes us not only more adept at detecting emotions, but also at expressing and thinking about them. Going back to my point of music being a language of pure emotion, just like speech makers have studied rhetoric and know how to quickly and succinctly make their point with their words and their tone, musicians study the emotion that music conveys, and they eventually get much better at detecting subtle variations and manipulations in this emotion. It’s not a stretch to carry this over from music to human interaction.
The effect isn’t like an on/off switch—it’s a part of the brain that’s like a muscle in that it gets stronger or weaker depending on how much and how often you use it. People who play music regularly for years have much more highly developed subcortical sensory circuitry than people who don’t. So picking up the guitar tomorrow probably won’t have an immediate effect, although playing several times a week for a few years will have a significant effect.
