What The Heck Is The Circle Of Fifths?

What the heck is the circle of fifths? Or is it Circle of 5ths? Hey guys, Brad Litton from SimpleGuitar.com with another beginner guitar lesson for you about one of the music theory things that confused the heck out of me when I was starting out learning guitar.

The Circle of Fifths sounds all complicated & hard to understand guitar theory stuff. But really it's not. So I break down the whole thing about the circle of fifths for this guitar lesson. And I know that I'm playing electric guitar in the video, but naturally this applies to the acoustic guitar as well.
