So here is B7. And uh, B7 you can make as an open chord. But uh, but there are plenty of reasons to make it as a barre chord. And here's two ways to do that. So I'm taking E7, right? My finger's free so I can barre and I'm making that at the 7th fret. So my barre is at the 7th, I have E7 down, but now this is B7. And then I can also do that with my A7 chord. I'm taking A and I'm moving to the 2nd fret. So here's the barre at the 2nd, what looks like an A7 chord but now it's B7. That's how you make B7 as a barre chord.
