The next chord we're going to learn is the C chord. And the C chord is one of the more commonly used chords and acoustic blues guitar playing, the C looks like this sounds like that. What I'm doing with the left hand, I've got my first finger on the first fret of the second string, got my second finger on the second fret of the fourth string, and I've got my ring finger on the third fret of the fifth string. I've got an open first string and I've got an open third string. So there is a C chord, that's a C major. The alternative base for a C chord can be done a couple different ways.
One way to do it is five, four and this is maybe the same cluster The most common. I'm just going to show you this one now and then a little bit later when we take a look at some of the songs and see we'll see some variations on this. But right now with a C chord, our fifth string and our fourth string. That's our alternating bass, five for alternating bass. The monotonic bass is going to be the fifth string with the third finger fretting it at the third fret. And again, we're muting that with that right hand call.
So the C chord, C major alternating bass, five for monotonic bass, the fifth string, a variation on the C major is the C seven. And just like with e and a, there's a seventh chord version. So what you do to make a C seventh is you just take your C chord and you take your pink Key and put it on the third fret of the third string. So now we've got this that is a C seven. When we play the C seventh chord, just like with the variations and the A variation, we're going to keep the exact same alternative base and the exact same monotonic base. So five for on the alternating base and the fifth string for the monotonic base.
So that is the C chord and the C seventh chord. You're going to need both of those
