Do you ever notice how one song can make your day? That's because music doesn't just enter your ears, it also works on your brain. It can actually
impact both your feelings and your memory. Like a special gift may make you feel warm and always remember the day you got it.
Music can lift your spirits in a great way. This is because music turns on a part of the brain called the amygdala, and it sends out special chemicals known as hormones（荷尔蒙）. One powerful hormone is dopamine（多巴胺）, which helps people feel happy. Music also encourages the brain to produce another kind of hormone called oxytocin（催产素）, which helps people feel close to each other.
Music also works on memory because when you listen to music, a memory area called the hippocampus becomes active. It helps store and recall information. Songs with fixed beats or repeated melodies（旋律）make the hippocampus more active. As a result, the brain can group, repeat and remember information better. Some language courses use this idea. They teach words and sentences with catchy songs.
What music does to our brain makes it very useful. Many people play soft background music while working, because it helps them relax and keep their mind on work. Students can also use music to review（复习）words: say them to the beat, or make a new song with the word list. In hospitals, music is sometimes used to help patients with memory problems. Songs from childhood can bring back old memories and help them feel safe.
Next time when you feel stressed out or forget what you have just learned, turn to music. Pick a song that matches your purpose, and let your brain reset.
