Watch the Day 15 online guitar lesson by Ravi from Learn Guitar in 21 Days
Until now, all the chords we have learned have been "Major" (people often think of major chords as sounding "happy"). Today we'll learn our first minor chord (minor chords often suggest "dark" or "sad"), the A minor. You'll notice that it looks a lot like the E major chord, except that everything is one string lower. So, your fingers will already have the muscle memory and it will feel familiar, but make sure you drop everything down by one string.
