Playing an E minor chord
Easiest chord first... playing an Eminor chord only involves using two fingers in your fretting hand. 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. Strum all six strings, and, there you have it, an Eminor 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.
