Watch the A Minor For All online guitar lesson by Brad Carlton from Chord Studies: CAGED Chords Vol. 1

In this example we'll use the A minor form out of the EDCAG system for both the A minor and B minor chords. Each chord is played for four beats. Finger the A minor chord with your second, third, and fourth fingers and keep your wrist under the neck, keeping your index finger in a barred position to the left of the nut. This way, your hand, wrist and forearm will all be in the right position as you shift from one chord to the next. Be careful to avoid sounding the sixth string with this form and use the tip of your index finger to mute it when possible.
