So we've been talking about moving from one chord to the other using base notes, right? We've been using our four chords G, Em, C and D. But now let's talk about once you get there what you can do to the chord. So, when I was a kid I can do somebody fooling around with D, right? All I heard them do is put down their pinky here. You know, maybe I saw that on TV or I heard that on recording you know. I saw then put down their pinky there in the middle of the strum. So I said, 'wow' that's beautiful. I have to be able to use that, you know. So I practice like crazy on just that one chord. Right. Then I saw somebody else do something with D were they lifted up their middle finger so you can do that too, right? So or maybe a combination of both. Right? So, now let me try to put that into our little pattern, right? G, Em, C, and D, right? And when I get to D I'm just gonna sort of fool around with it. Anything that comes to mind, right? Do I go G, E Minor, and C and then D. I'd say how much more interesting now our song has become. Now, of course D is not the only one I could do that to. You could do that to C, right? For C to fool around with we can put our pinky right here on the fourth string, third Fret. So, right. Interesting sound and then I let go. Back to normal, right? So how about if I do all the strum. Down. Right. Down, down, down, up, up, down, right? So, let's put that in our pattern, right? When I get to C. When I fool around. When I get to D, I'm gonna fool around right? So I have G, E Minor, C this time I'm gonna fool around with it and then D. How about if I put some of the bass notes. Right? Playing with C. Right. See how much interesting that could be. So that's a nice way of playing around with the chords.
