What's the difference between classical music and rock music?

Don't you know the types of classical music? Classical music is usually played by western traditional instruments, such as violin and cello, or China uses some dulcimer or pipa.

Generally, they are soft and have no electronic components. It is purely instrumental.

Rock electronic elements are relatively strong, generally using electric guitar or electronic organ, which is more diverse. There are many elements mixed together, but they are noisy. More intense. Personally, I don't like either, but I hate rock and roll even more, because it's so noisy that I can hardly recognize the tone. Although it is called music, it has no musical elements at all.

I think things like jazz and blues. Pop and j-pop are better. In addition, the style of blues is very popular. It is a kind of jazz. Hip-hop is also a favorite of many people, which is rap.
