Not to mention whether the teacher is extinct or not, at the age of fifteen, there will be a desire to learn classics. Such children will soon be extinct. I hope you are not impulsive. Nowadays, fewer and fewer people like classics ask interesting questions about whether they can learn by themselves. First of all, the idea of self-study is very good, but it takes a lot of effort to do it, because learning and practicing the piano itself is a dull one. Things, let alone self-study, first look at how you master music theory knowledge, have a good music theory knowledge base, self-study can be a little easier, now everything on the Internet ah, guitar score, video, want to self-study is absolutely OK, but what can be learned is your own thing, so it is necessary to ask yourself whether you can self-study, and finally sum up, personal. I think you can learn by yourself, but it’s more difficult, because there are too many skills and it’s hard to find. Finding a teacher will make you less detours, and even a bad teacher can lead you to the beginning, right? When all the teachers can’t teach you, you can go to self-study. What do you think?
