This is what some laymen say. . . . . . Playing the saxophone doesn't actually make your face look bigger. Look at the Japanese saxophone idol Kobayashi Kaori, isn’t she still young and beautiful? When a girl plays the saxophone, she is quite charming and cute. For the basic structure of the saxophone and how to play it, just go to your teacher! Teachers will tell you that if you want to find a teacher, it is best to find someone from a singing and dancing troupe. Most of the teachers in piano shops are also monks who have become monks. At best, we can only briefly teach you how to maintain your instrument. The saxophone is expensive, and it is also very fragile. It may break if dropped. So you should always take care of it, just like you would treat your dear ones. After blowing every day, clean the saliva in the tube and put it in the box to avoid oxidation. If you want to learn the saxophone, you can learn it as long as you want, it doesn't matter. But I personally think that playing in elementary school or junior high school is the most suitable period, because in high school, studies are too intense. Not to mention learning saxophone, there is not even much time to practice. . . . . . It’s a grade exam! Basically, your saxophone teacher will tell you that there will be a test every year, but the time is different. In the grade examination, they will test scales, an etude and a piece of music. Basically, it is over before you finish playing and the judge and teacher think it is OK. But I personally feel that the grade exam is meaningless. If you pass the grade exam, you will get a certificate at best and nothing else. To put it bluntly, this is just a stage exam. Finished answering. . . . . .
