[NoQuestion]

Okay...where do I start? I am teaching myself guitar notation and I am stuck on something. This is the fourth message board I've been to with this problem, so I am REALLY hoping someone here can help me. I take no guitar lessons and I never have. Now, on my guitar dvd that I bought a few months ago there is a song called "Etude." The dvd is now teaching me about moving thirds in that song. The song starts with open G and open B for the first chord. The next chord is A and C. The next chord is G and D. And the guy on the DVD says to play G with a B instead. And that is supposed to be a moving third. But how do I know when to play G with a B on any other song because there is no sign indicating that it is a moving third chord. Does that make sense? And further more, can you actually explain to me exactly WHAT a moving third IS and how I am supposed to play them with other songs? Because the dude on my dvd says absolutely nothing about them except that you change that one note on that one chord. Confused? I sure am! So please reply....and I'll wait.
