A band I really enjoy put out a tab book so I purchased the e-book version. I am having trouble deciphering some of the symbols used above and below the staff. I think they might be actual sheet music notation. I'm wondering if ultimate guitar has a guide to these notations? I tried searching but couldn't find anything that helps. Maybe somebody has an outside source that could help me?

If you guys have no clue what i'm talking about I can add pictures.

Tab book was put out by Sheet Happens.

Thanks in advance!
