"Now for our next seven chord, we're going to create the A seven. We'll create that first by creating the A major and comparing them, contrasting them. So, remember, for A major, you want to put your second finger on the second fret of the D, third finger, second fret of the G, and pinky underneath. Okay? Now the difference here is instead of having the A octave, you want to have an open G. Now, it's not as simple as just picking up your third finger because then you have this awkward shape where you're using your second and your fourth finger, for an A seven. What you can do is you can replace that fourth finger with your third finger. So now, A major, to an A seven, just replace the pinky with your third finger and keep that G open in between. You could also, if you wanted, use your first and second, first and third, anything like that. I recommend the A seven being played like this, so you can see how it relates to the regular A major. Now the A seven is a dominant chord, as a five-seven, it wants to lead to the chord D. Notice how this is the same theory as when we used the fourth. From one. And this always being the four, well, if this is five, then this is always one on the low strings, on your low E, A, and D strings. So try moving from the A seven to the D major. See how your second finger has to do some swinging there. That will give you the real impact of the A seven chord."
