Watch the E major in 2nds online guitar lesson by Brad Carlton from Guitar Lab: Chord Scales Vol. 1
This lesson will take the same information that you learned in the previous lesson and apply it to the 3rd and 2nd strings. The 3rd and 2nd strings are the only pair of adjacent strings that are tuned a major 3rd apart. All of your other adjacent string groups are tuned a perfect 4th apart.
