About erhu, pipa, guzheng, piano and bamboo flute, please master it and ask Teacher Cai to have a look.

I'm glad to tell you that I know a lot about the instruments you mentioned!

Of course 1 can learn together. I like to play pop music with erhu, and they are all three instruments. If you have a foundation, it will be easy to learn.

You can learn the piano, but you are 15, right? I suggest you not to spend too much time on musical instruments. The class in senior one is very long, so you should study hard.

In fact, these four instruments are almost the same, but I suggest you learn erhu, because you can get extra points in the college entrance examination, with the greatest probability.

Don't be too old, hehe, erhu usually takes two weeks to practice posture and then you can play it. I don't know what level you are talking about. If you are level one, it only takes a month, and the guzheng only takes a few weeks. This is the fastest way to get started. I haven't learned the pipa, but it's similar. The flute is very simple. Generally speaking, these four musical instruments can be played alone for four or five years, with high talent. You can play the hymn (level 6), but you did have some injuries at first, such as your hand was cut when you put down the erhu and your hand was sore when you lifted the flute, but it was definitely not as scary as what you said upstairs.

Of course, the ranking is erhu, guzheng, pipa and bamboo flute, but those who have studied violin are not afraid, and erhu and violin are the most difficult to tie!

Also, because I am your senior, hehe, you can also send a text message asking me if I can't!
