"We're going to talk about A Major 7 as a barre chord. First, what we should do is talk about the shapes that I'm going to use, in order to make A Major 7 as a barre chord. I'm going to use an E Major 7 shape and an A Major 7 shape, in order to make A Major 7 as a barre chord. How do I do that? For E Major 7 shape, I'm going to take my 1st finger and I'm going to put it on the 4th string 1st fret. Then I'm going to take my 2nd finger and I'm going to put it on the 1st fret, but on the 3rd string. And then, my 3rd finger I'm going to put all the way up here on the 5th string 2nd fret. It's a little awkward. But that is the shape. E Major 7, very jazzy sound, right. Now, in order to make a barre chord out of that, I have to adjust my fingers so my 1st finger is free. Right? So, I'm just going to switch around my fingers a little bit, and get my 1st finger free, look how I do that. Now, I'm going to bring that shape all the way up to A, which again here is at the 5th fret. And so, here you go. A Major 7 as a barre chord.
Then you can also use the A form of that to make A Major 7. This is the shape here. And what we're going to do is you're going to but your 1st finger on the 3rd string 1st fret, and then your 2nd finger on the 4th string 2nd fret, and then your ring finger is going to go on the 2nd string 2nd fret. A Major 7, all right. Again, I just going to switch that around so I have my 1st finger free and so look how I did that. First, like that, then I just switch it around so that this finger is free. Now, in this case, we already have A Major 7 but just to prove that it can be a barre chord, we're going to go all the way to the 12th fret. That's where the guitar starts again, make that shape.
