I feel the genres that I know well are research papers/persuasive (non- fiction), tragedy, and romance. I learned them from being assigned the genres in high school to write about. The common rhetorical features of Research papers are that you are ultimately trying to persuade the audience to believe a specific argument or theory. For Tragedy, you want to make the piece emotional and leave the reader heartbroken or shocked in a way. For romance, the piece tends to be an emotional roller coaster, for example switching between happy and sad.
I don’t really like a having a lot of freedom while writing because I feel like a start to get off topic really easily. I find it to help if I have a certain form to follow because it helps me understand the point of why I’m wring and also helps me stay on topic much easier than having a lot of freedom or flexibility.
