Watch the B Minor Chords online guitar lesson by Rich Maloof from Acoustic Guitar For Beginners
The B minor (Bm) is unlike any chord we've seen since it's not played within the first three frets. But there's nothing magical about playing up the neck a little bit.
Again we're going to learn something new by working with something old. So start with the A minor (Am) shape you already know. Just make sure to play it with your middle, ring and pinky fingers. Move that Am up two frets, plant the bass note with your index finger, and you'll have Bm.
You can let that high 1st string ring out, mute it, or try barring across the second fret for a totally legit Bm chord. Don't let it trip you up - there are a number of workarounds.
