I once took an art class, music app

I once took an art class, music appreciation class, which impressed me deeply. In this course, I learned that music can affect people's emotions. Positive music rhythm can make people feel excited. The soft music rhythm can make people relax. This is a very magical thing. This class told me that I can use music to regulate my emotions in daily life. When I am exhausted, I can listen to some pure music to relax myself. When I feel sad, I can also listen to some lively music to adjust my mood. I can also use this method in my own film and TV works to let the audience know more about the emotions I want them to feel.
