Playing an E major chord
Playing an Emajor chord is actually very similar to playing an Aminor chord; you just need to switch the strings you are playing the chord on. Start by placing your second finger on the second fret of the fifth string. Now, place your third finger on the second fret of the fourth string. Lastly, place your first finger on the first fret of the third string. Strum all six strings and you're playing an Emajor chord.
Now, like last lesson, test yourself to make sure you're playing the chord properly. Starting on the sixth string, strike each string one at a time, making sure each note in the chord is ringing clearly. If not, study your fingers, and identify what the problem is. Then, try to adjust your fingering so the problem goes away.
