First of all, learning guitar must be formal, not ready-made When you first started studying, you didn't have enough ability to judge whether what you saw on the Internet was really professional or not. A good teacher who has patience, methods and skills in the early stage can help you lay a good foundation, and it will become easier to play any music after you have a solid foundation. Don't teach yourself in the early stage, because there are so many important details that you can't tell right or wrong independently. Once the wrong playing habits are formed, it takes a long time to relearn and correct them. Try to have certain technical ability and knowledge of music theory before considering self-study. There is not much time left to practice the piano in work, study and life. Try not to take too many detours. I wish you success! . .
