Shows this better. It's in the beginner section go to the home page and look over at the right hand side --.Good luck :)
PS. If you're using an acoustic you may find it difficult to hold the strings down as they are quite thick and stiff and you may want to borrow an electric to get the "hang" of bar chords. Cheers.
