Let me show you how to play the D and F sharp. You are going to take your 2nd finger and put it on the 6th string 2nd fret. You are going to take your 3rd finger and then you are going to be putting it on the 3rd string 2nd fret.
Finally, to finish the chord, you are going to take your 4th finger and you are going to put it on the 2nd string 3rd fret. So, by self, it sound like (Guitar playing) it is kind of like a D chord but with a deeper bass into it (Guitar playing). So, that is a D and F sharp chord.
