To answer the first question, I know a girl who is engaged in tuning. When chatting, she would say that tuning is not suitable for girls because she is too tired. For example, if you undertake a performance, it must be hard in the wind and rain, and some lines on the scene must be installed and debugged by yourself. I think she is right.

I don't think there is much difference between girls doing this major (music art major) and boys doing this major (music art major). As long as their own things and works are good, they will definitely be sought after, and then they will be actively operated.

according to your situation, you haven't received formal music training, have you? I think what to start with is the simplest singing, vocal training and learning basic music theory knowledge. In your spare time, you can learn instruments such as guzheng piano, erhu guitar, bass drum set and so on to enrich your performance ability.
