I've been playing cello for 10 years. I'm going to watch this video. According to the video, when a person plays music, the human brain does a lot of exercise as if it were setting off fireworks. When listening to music, the brain does interesting exercises, but when it comes to music, the brain does more exercise than the brain just listening to music. In particular, there is excellent development and action in memory functions. The brain of a person who has been playing music for a long time shows that it has developed in many areas of the brain. After watching this video for a long time, I thought I was really a musician because I'm not very good at anything. However, I couldn't understand when others said I was smart, but after seeing this video, I began to wonder if I was really smart. I have to study and play instruments harder to master my brain!
