Does music really help you concentrate?
Many people listen to music while they’re carrying out a task, whether they’re studying for an exam, driving a vehicle or even reading a book. Many of these people argue that background music helps them focus.
It’s not clear why the brain likes music so much in the first place, although it clearly does. Interestingly, there’s a specific spectrum of musical properties that the brain prefers. Experiments by Maria Witek and colleagues reveal that there needs to be a medium level of syncopation in music to elicit a pleasure response and associated body movement in individuals. What this means in plain English is: music needs to be funky, but not too funky, for people to like it enough to make them want to dance.
Your own experience will probably back this up. Simple, monotonous beats, like listening to a metronome, aren’t really entertaining. They have low levels of syncopation and certainly don’t make you want to dance. In contrast, chaotic and unpredictable music, like free jazz, has high levels of syncopation, can be extremely off-putting and rarely, if ever, entices people to dance.
