Rhetoric is much more complicated than just those three devices, though they can be especially persuasive. Rhetorical analyzes are extremely extensive and take many different things into account. It is important to note that Rhetorical Analyses are not summaries of content, but an extremely detailed analyses of the way the writer achieved their point (Short).
The goal of a rhetorical analysis is to articulate HOW the author writes, rather than WHAT they actually wrote- Lindsay Short
In class we were given some ideas on what to write when doing the visual rhetorical analysis these things included: purpose, audience, stance, context, genre, tone, arrangement, location, scale, text, color, and readability. The thing that all of these things have in common is that they could be used to help the author achieve his point.
Once you know the types of things people are looking for when they analyze your work, it makes it infinitely more difficult to build something because you become obsessed with the details. Being able to do a rhetorical analysis and also create something for a purpose takes persistence and creativity. You have to also engage fully with a topic, and have full command of what you are trying to accomplish.
The creativity and persistence comes in when you have to make choices, and try to understand what others are going to get from that choice. The example given in class talks about how something as simple as how fast and often the video is cut away to another scene can change the way the person sees the information, whether they thing it is suspenseful, scary, or boring.
In high school the teachers always tried to get us to engage with the settings of the plot, and there is always something in it that the teachers think means something while we just kind of think the teacher is thinking too hard about it. For example she argues that the blue curtains mean the character is sad and depressed, while we argue that the character just liked the blue curtains because they were pretty. Potato potahto. In the eyes of the rhetorical analysis the curtains and everything else mentioned in that scene is part of the grand scheme of things, and most definitely could mean that the author made those curtains blue to reflect the emotions of the character.
