Listening to white music is very helpful, while listening to other types of music is not. This is important to help me with my outline because it throughly explains what each type of music does for your brain.

any 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.

Why, though? When you think about it, that doesn't make much sense. Why would having two things to concentrate on make you more focused, not less? Some people even go so far as to say that not having music on is more distracting. So what's going on there?

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.

The middle ground ( funk music like James Brown is what the experimenters reference most) hits the sweet spot between predictable and chaotic, for which the brain has a strong preference. Most modern pop falls somewhere within this range, no doubt.

Paying attention

Why would music help us concentrate, though? One argument is to do with attention.

For all its amazing abilities, the brain hasn't really evolved to take in abstract information or spend prolonged periods thinking about one thing. We seem to have two attention systems: a conscious one that enables us to direct our focus towards things we know we want to concentrate on and an unconscious one that shifts attention towards anything our senses pick up that might be significant. The unconscious one is simpler, more fundamental, and linked to emotional processing rather than higher reasoning. It also operates faster. So when you hear a noise when you're alone at home, you're paying attention to it long before you're able to work out what it might have been. You can't help it.

The trouble is, while our conscious attention is focused on the task in hand, the unconscious attention system doesn't shut down; it's still very much online, scanning for anything important in your peripheral senses. And if what we're doing is unpleasant or dull - so you're already having to force your attention to stay fixed on it - the unconscious attention system is even more potent. This means that a distraction doesn't need to be as stimulating to divert your attention on to something else.

Some ​people argue that one of the best music genres for concentration is the video game soundtrack

Have you ever worked in an open-plan office and been working on a very important task, only to be driven slowly mad by a co-worker constantly sniffing, or sipping their coffee, or clipping their nails? Something quite innocuous suddenly becomes much more infuriating when you're trying to work on something your brain doesn't necessarily enjoy.

Music is a very useful tool in such situations. It provides non-invasive noise and pleasurable feelings, to effectively neutralise the unconscious attention system's ability to distract us. It's much like giving small children a new toy to play with while you're trying to get some work done without them disturbing you.

Type of music

However, it's not just a matter of providing any old background noise to keep distractions at bay. A lot of companies have tried using pink noise (pdf) - a less invasive version of white noise - broadcasting it around the workplace to reduce distractions and boost productivity. But views on the effectiveness of this approach are mixed at best.

It seems clear that the type of noise, or music, is important. This may seem obvious: someone listening to classical music while they work wouldn't seem at all unusual, but if they were listening to thrash metal it would be thought very strange indeed.

While the nature and style of the music can cause specific responses in the brain (funky music compels you to dance, sad music makes you melancholy, motivational music makes you want to keep fit), some studies suggest that it really is down to personal preference. Music you like increases focus, while music you don't impedes it. Given the extreme variation in musical preferences from person to person, exposing your workforce or classroom to a single type of music would obviously end up with mixed results.

Music also has a big impact on mood - truly bleak music could sap your enthusiasm for your task. Something else to look out for is music with catchy lyrics. Musical pieces without wordsmight be better working companions, as human speech and vocalisation is something our brains pay particular attention to.

Video game soundtracks

Some people argue that one of the best music genres for concentration is the video game soundtrack. This makes sense, when you consider the purpose of the video game music: to help create an immersive environment and to facilitate but not distract from a task that requires constant attention and focus.

Limitations in the technology used for early games consoles meant the music also tended to be fairly simplistic in its melodies - think Tetris or Mario. In a somewhat Darwinian way, the music in video games has been refined over decades to be pleasant, entertaining, but not distracting. The composers have (probably unintentionally) been manipulating the attention systems in the brains of players for years now.

There are signs that, as technology progresses, this type of theme music is being abandoned, with games producers opting for anything from big orchestral pieces to hip-hop. The challenge will be to maintain the delicate balance of stimulation without distraction. To achieve this, games composers will need to stay focused. Which is ironic.

Many of us listen to music while we work, thinking that it will help us to concentrate on the task at hand. And in fact, recent research has found that music can have beneficial effects on creativity. When it comes to other areas of performance, however, the impact of background music is more complicated.

The assumption that listening to music when working is beneficial to output likely has its roots in the so-called " Mozart effect", which gained wide media attention in the early 1990s. Put simply, this is the finding that spatial rotation performance (mentally rotating a 3D dimensional shape to determine whether it matches another or not) is increased immediately after listening to the music of Mozart, compared to relaxation instructions or no sound at all. Such was the attention that this finding garnered that the then US governor of Georgia, Zell Miller, proposed giving free cassettes or CDs of Mozart's music to prospective parents.

Subsequent studies have cast doubt on the necessity of the music of Mozart to produce this effect - a " Schubert effect", a " Blur effect", and even a " Stephen King effect" (his audiobook rather than his singing) have all been observed. In addition, musicians could show the effect purely from imagining the music rather than actually listening to it.

So researchers then suggested that the "Mozart effect" was not due to his music as such, but rather to people's optimum levels of mood and arousal. And so it became the " mood and arousal effect ".

Unfortunately, the situations in which most mood and arousal effects are observed are slightly unrealistic. Do we really sit and listen to music, switch it off, and then engage in our work in silence? More likely is that we work with our favourite tunes playing in the background.

How sound affects performance has been the topic of laboratory research for over 40 years, and is observed through a phenomenon called the irrelevant sound effect. Basically, this effect means that performance is poorer when a task is undertaken in the presence of background sound (irrelevant sound that you are ignoring), in comparison to quiet.

To study irrelevant sound effect, participants are asked to complete a simple task which requires them to recall a series of numbers or letters in the exact order in which they saw them - similar to trying to memorise a telephone number when you have no means to write it down. In general, people achieve this by rehearsing the items either aloud or under their breath. The tricky thing is being able to do this while ignoring any background noise.

Two key characteristics of the irrelevant sound effect are required for its observation. First, the task must require the person to use their rehearsal abilities, and second, the sound must contain acoustical variation - for example, sounds such as "n, r, p" as opposed to "c, c, c". Where the sound does not vary much acoustically, then performance of the task is much closer to that observed in quiet conditions. Interestingly, it does not matter whether the person likes the sound or not. Performance is equally as poor whether the background sound is music the person likes or dislikes.

The irrelevant sound effect itself comes from attempting to process two sources of ordered information at the same time - one from the task and one from the sound. Unfortunately, only the former is required to successfully perform the serial recall task, and the effort expended in ensuring that irrelevant order information from the sound is not processed actually impedes this ability.

A similar conflict is also seen when reading while in the presence of lyrical music. In this situation, the two sources of words - from the task and the sound - are in conflict. The subsequent cost is poorer performance of the task in the presence of music with lyrics.

What this all means is that whether having music playing in the background helps or hinders performance depends on the task and on the type of music, and only understanding this relationship will help people maximise their productivity levels. If the task requires creativity or some element of mental rotation then listening to music one likes can increase performance. In contrast, if the task requires one to rehearse information in order then quiet is best, or, in the case of reading comprehension, quiet or instrumental music.

One promising area of the impact of music on cognitive abilities stems from actually learning to play a musical instrument. Studies show that children who are being musically trained show an improvement in intellectual abilities. However, the reasons behind this are, at present, unknown and likely to be complex. It may not be the music per se that produces this effect but more the activities associated with studying music, such as concentration, repeated practice, lessons and homework.

music does not help you study or focus. This is important because it explains that music really doesn't do anything for students or people studying. Researchers say they don't know why students still listen to music while doing assignments or studying.

There is a wealth of psychology research that can help teachers to improve how they work with students, but academic studies of this kind aren't always easy to access or translate into the realities of classroom practice. This series seeks to redress that by taking a selection of studies and making sense of the important information for teachers, as we all seek to answer the question: how can we help our students do better at school? This time, we consider growth mindset.
Many students do their homework and revision while listening to music. Many of them will swear that listening to their favourite songs makes them study better. But does music help or hinder learning? And does it matter what type of music you listen to while revising?

Researchers from the applied psychology department of Cardiff Metropolitan University led a study to answer this question. The authors, Nick Perham and Harriet Currie, assigned students into one of four groups: the first revised in silence, the second revised while listening to music with lyrics they liked (which included songs from One Direction and Katy Perry), the third group revised to music with lyrics they did not like (which comprised of very heavy metal bands), and the fourth group revised listening to music without lyrics.

The participants then took a test on the passages they had been revising, rating how distracting their environment had been, as well as writing down their predictions for how well they thought they had done.

What are the main findings?

1. Students who revised in quiet environments performed more than 60% better in an exam than their peers who revised while listening to music that had lyrics.

2. Students who revised while listening to music without lyrics did better than those who had revised to music with lyrics.

3. It made no difference if students revised listening to songs they liked or disliked. Both led to a reduction in their test performance.

4. Students who revised in silence rated their environment as less distracting and accurately predicted that this would lead to better performances in subsequent tests.

Related research

There are some benefits to listening to music while performing certain tasks. It can be quite motivating and it can improve mood (listening to your favourite song tends to make people smile, for example). But it does not help people learn new or complex material.

The misconception that music does help us learn stems from a series of studies linked to the " Mozart effect ", which found that people performed better on a series of cognitive tasks after listening to 10 minutes of Mozart. Participants in these studies appeared to be getting smarter and performing better in tests.

However, further research has since revealed this is not the case. While listening to music before a task can make someone feel better, listening to it while trying to learn something new tends not to help. This is because music - especially tunes with lyrics - can take up processing space. This conflicts with the material you are trying to learn, effectively creating a bottleneck in your memory, as there is less space to process what you are revising.

What does this mean for the classroom?

It is important that students are made aware of the pitfalls of listening to music when revising. Perham and Currie's study found that students rated the quiet environment as less distracting and better for them, yet many students continue to listen to music during their homework. Why? Perhaps they're doing so out of habit, or they confuse what improves their mood with what leads to good revision, or it alleviates boredom. Perhaps it's simply because everyone else is doing it.

Students need to know how to revise well. There may well be a time and place to listen to music during the course of their revision, but not when they are learning new and complex material. After all, silence is golden.
