Rhetorical high style is a form of writing or speaking that is characterized by its elevated, formal, and elaborate language. It often includes complex sentence structures, rich vocabulary, and a focus on aesthetic qualities. This style is
typically used to convey grandeur, seriousness, or importance, and is often
found in speeches, classical literature, and formal essays. High style aims to
persuade or impress the audience through its eloquence and sophistication, often appealing to emotions and intellect simultaneously.

Yes, several famous public speakers are adept at switching between high style
(formal, eloquent language) and low style (informal, conversational language).
One notable example is Barack Obama. As a speaker, he is known for his ability
to adapt his style to suit different audiences, seamlessly transitioning from
formal, high-stakes speeches to more relaxed, conversational settings. Another
example is Oprah Winfrey, who can engage audiences with both her polished,
inspirational speeches and her warm, approachable conversational style. This
versatility helps them connect with diverse audiences and convey their messages effectively.
