How to Fingerpick A Major Chords

"So, we just did the E chord. The chord, at least in blues scales, that goes with E is A, is the other kind of chord that kind of goes along well with it. So, from an A chord, there's a couple of ways to play an A. I usually cheat when I play an A, by just kind of putting my finger across all three of these. And if I do that, the note I mainly like to add to it is this note here, which is basically the note, if I was playing a D chord, but, so, kind of adding that note to an A can kind of have a neat sound. Kind of like. But, of course, the problem with playing an A like this is now I can't really play the high E note, because my kind of finger's over it. So, what I can do is now play this kind of more in this shape and now I can add that seventh. So for an A chord, this note here on the third fret makes it a seventh. So I can go. Okay, so those are ones I like to do in A."
