Because all aspects of guqin are self-contained, such as notation, fingering, ups and downs of playing, different playing methods of playing factions and so on. If beginners just grope for themselves, it is difficult to accurately understand and master without the guidance of teachers, they will take many detours, fail to find their own problems in time, and easily ignore problems such as intonation.
What's more, some mistakes, such as basic fingering, are hard to change once they become habits. Therefore, it is best for beginners to learn guqin with the guidance of teachers. This is especially important in the initial stage.
Precautions:
1, to choose good teaching materials, there are some discs or something, and you can even watch video teaching online, but it should be noted here that it is guaranteed to try to find some audio-visual products of teachers with strong strength. When you first start learning, ask a teacher to learn. Learning more is not good. It's not too late to learn from other teachers when you have a certain level.
2, before learning the piano, whether there is enough interest. There are some objective things ahead, which are necessary, but not the most important. Before self-study, you must know whether you like guqin, whether it is just a whim, or whether you have a strong interest. If you just want to show off or put on a show, you don't have to learn.
