The great irony here is that the one time I truly started to understand Chinese tones was when it was explained in terms of how English speakers already subconsciously use tones. I think I get what you mean. Correct me if I'm wrong.

Like English, Korean uses tones as a channel for metadata, not as a direct part of the encoding set. You can annotate parts of the sentence with tones, such as marking something a question or highlighting certain information as important, but you can't wholesale change whats being said.
