Watch the The E chord online guitar lesson by David Hamburger from Blues Guitar For Beginners
You can make a whole lot of music with just a handful of chords. In fact, John Lee Hooker proved that you could play the blues with just one chord and make it work. It may take a little time to get these first few chords under your fingers, but once you've learned them, they're yours forever, and as long as you play the guitar you'll definitely be using A, D and E - they never go out of style.
