First time I have used the Forum so I don't even know what to put in the "Title" Anyway, I am learning to play guitar because I am old. I think you need to keep putting new patterns into your brain, least you lose the ability to do so. I am 68 and yes it takes time but that is the beauty of it for me. I just love doing it. I have gotten over thinking that everyone else just pucks the thing up and plays. I have been working for five days on the first bar of Oh Dannyboy, go figure. That F Barr chord is a wonderful thing as it is the E Form that opens up so many other chored for you. F at the first and G at the third and A at the 5th and so on. House of the Rising Sun is a good Song for the F barr chord.
