Music is an art form which deals with the representation of emotion through the medium of sound. It can have a physical effect on us because it is closely linked with emotion, perhaps even more than the abstract nature of words. The number one reason why people listen to music is to adjust their emotional state. 36
Numerous studies leave us in no doubt that music can affect our mood state and stress level. 37 For example, they have found that background music shuts out distractions. It calms them before a large task and then they can stay focused for longer. Also it can help their creativity and make studying more enjoyable.
38 Firstly, it depends on what the task it. The more difficult the challenge is, the more likely background music will interrupt the learning process. For less challenging learning tasks, music can greatly assist in providing a positive learning state. Secondly, it depends on the characteristics of the music we'll come to in a moment. And thirdly, extroverts（性格外向 者）enjoy and often require more external stimulation(刺激）and are likely to handle background noise better than those who are quiet and shy.
Actually, it's not about the genre（类型）of music, but the natural musical characteristics which aid or disrupt study. One of these characteristics is the tempo （拍子). The recommended tempo for background music is in the range 70-110 beats per minute, slightly faster than the heartbeat at rest. 39 And very slow music lowers the heartbeat, creating a state that might be too relaxed for study purposes.
In addition, lyrics（歌词）are the most distracting aspect of background musical listening.
40 More particularly, studies have found that the most distracting background is fast and familiar vocal music, chosen and liked by the listener.
