I am left handed and trying to learn how to play the guitar. I have two questions: 1. Should I buy a left handed guitar? The one I have now is a right handed one that I flipped the strings on. 2. Will this program help me learn? I've read things on the internet where it says that the chords are different and TAB is written different but I am not sure if that is true.

Any thoughts and advice will be appreciated. Thanks!!
