Many people didn't work hard to persevere. After learning for a while, they felt that they lost the freshness, and they were not as beautiful as they imagined or seen on TV, so they gave up!
If you can learn how to play the guzheng in three days, the streets will be full of performers, and you can ask yourself again? How much thought and time do you spend on the guzheng every day? Three minutes on stage, ten years off stage. If not, then you do not need to force you to learn the guzheng for a year and a half to the level you see on TV. This is a process from quantitative change to qualitative change.
From the perspective of learning the guzheng itself, you are learning how to control your brain and fingers. In a big way, you are not only learning the guzheng. You're still learning how to get your brain moving and how to control your behavior! You have achieved both of these aspects, and it can be said that you are no longer an ordinary person. In the future, when you are doing anything, you will first use your brain to think about how to succeed or achieve your own expectations. How to control your behavior when you are angry or tempted, this is what a good guzheng teacher can give you!
Regarding self-learning guzheng, the editor thinks that not only guzheng, but any musical instrument, if you are a self-study persevering person, you must get something, but the effect must be very small. A good teacher is like a guide in the labyrinth, which can help you avoid detours. But if you have a good teacher and you are lazy and don't think about it or practice, it won't work!
