Ok..

A lot of times when people put tab, they get comments like "can you show how to strum this?" or "umm how do u strum becuz I cant tell on tab?" 

The tab is not there to tell you how to strum.  Neither are the chords over the words there to tell you the strums pattern.

When you get the tab, listen to the song and match the strum with your ear as best you can.  It is okay if your strum doesnt match it 100%!  

Some easy strum patterns are: (^: strum up, |:strum down)

1. |^|^|^|^|^
2.|^^|^^|^^|

4.|^|^|^||^|^||
 Just mix it around and relax the strumming will come natural after a while!! The strum is the hardest part of playing.. once u get it down, you will be set!
