How to emphasize body text?

I’m not sure if this is the right place to post this…

I’ve been having trouble with emphasizing body text, for example one of the assignments I have is to create 3 different layouts for a greek letter. One for emphasis on the title, one for the symbol and one for the body text. The title and symbol are relatively easy but how can it be done for the body text? Also, you are only allowed to use a single font family.

I can’t seem to find any good examples of this done since usually the body text is not emphasized over the title/image :s

Here’s what I came up with so far :/
