Have you ever thought about why malls, restaurants, and even theaters have music? Well, to understand this, you simply just look back at how you felt when you heard music in these places. Music is known to improve the mood of people. Often music helps us pay attention to what we are doing. Music helps patients feel good and helps them recover faster and better.

Depression（沮丧) is a state of mind that most of us experience at some point of time. There are some periods in our life when everything seems difficult. It seems that everything is getting worse and we have no control over our life. Studies have shown that music can be an important mood lifter in such situations. Music also plays a great role in making us feel less nervous or worried. Anxiety(焦虑) can often cause loss of sleep and other illnesses.

Music is often known as an international language. We may not know the language another person is speaking, but most of us respond to music in the same way. Music can often be the best way to connect with someone.

Music is one of the best ways to improve your moods, but this can depend largely on the kind of music you listen to. While happy music can certainly make you feel better, sad music can further lower your spirits. Listening to classical music can often make you feel a lot more powerful, while soft music can be the perfect way to relax at the end of a long way. If you want to use music to change the way how you are feeling, you need to understand the role of it, learn to recognize the kind of music that lifts your mood and helps you feel better. Once you realize the kind of music you can use, you can use it to change the way you feel. The right kind of music can be the perfect way to help us feel happier.
