ok my first post...im not a complete newbie ive got most the basic concepts down of guitar. But this one thing i cant seem to figure out. How in teh world do u knw in which way you are suppose to play a cord. For instance, i see a song tab that says to play a G, but then there is so many ways to play it, I dont know which way to do it. So maybe someone can point me in the right direction.
