The biggest issue is the lack of a standardized format for tabbing music for the harmonica. Occasionally, the parentheses and backslashes can be used for indicating bends. Also, they can indicate pushing in the slide on a chromatic harmonica tab. Sometimes the slash is used to break up the music into measures and sometimes parentheses are used to group multiple notes that are played together. It really depends on the person who wrote the tab, and what kind of harp the tab is for (diatonic or chromatic).
If I use something that might be misinterpreted or isn't necessarily clear, I'll usually put a note in the tab explaining what my notation means. I have since pretty much standardized the way I write tabs, but they don't all match up, especially among some of my earlier postings.
