Ms. McCormick is teaching the Em chord, which involves fretting 4th and 5th string on the second fret. However, to get a "richer sound", she instructs to hit just the bass note (6th string) and then skip over the next two strings. 1:05-:1:30 in video.
I'm wondering why even bother fretting 4th/5th strings on the second fret if it's advisable to just hit strings 6, and then 3, 2, and 1. Shouldn't this song just be played with all open chords? What is gained by fretting strings you are instructed to avoid?
Any clarification appreciated!
