Let's talk about B7. B7 is a little bit of a tricky chord because you have to use all four of your fingers. What we're going to do is we're going to put our second finger on the fifth string, second fret. Then your first finger is going to go on the fourth string, first fret. Then your third finger's going to go on the third string, second fret. And then my pinky's going to go on the first string, second fret. So look at that, all four fingers on that. Here, I'm trying to be careful, and I'm only trying to strum the last five. And B7, all it wants to do is get to an E. So B7, here's E minor, let's say. And that's it, that's how you make B7.
