Hey, I'm trying to learn some new songs by looking off tabs on the Web, and I keep running into tabs that have weird things on them, for instance, and this is just an example, some might say
----5p2 or ----3h4 or 3x3x3x3x3x or ---7b-6-
What do the p, h, x, and b mean?! It's been driving me crazy. Also, how would you go about doing those things?
