No problem. As a teacher who studies music and then teaches music, I tell you that music is something that needs to be experienced with your heart. It has little to do with the junior high school education you mentioned, but you must study hard. Some music theory knowledge, including the harmonic forms that you will learn later, will require some math calculations, so it is not a problem.

If you really like it, I support you! Even if you are not a major, it is just a simple hobby. If you need anything, you can always come to me, I will be happy to help you! O(∩_∩)O~ Come on!
