When I started playing guitar to accompany songs I was lazy and didnt learn Barre Chords - Then I had a Motorbike accident and broke my left wrist . This involved re-learning the guitar , and at this point I included Barre Chords . Best thing I could have done ! It means that
I can play a lot more stuff , and dont have to keep worrying about capos and the inevitable tuning tweaks . A good idea is to practice the basic Chord run in as many keys as you can think of -C,Am,F,G,G7 then G,Em,C,D,D7 etc . If you can play these runs in A ,C ,D ,E ,F , and G you will be able to play the chords in Most songs without any trouble . As Amos said , you might as well join the Cat and see how long it takes for us to drag you down to our level . Best Of Luck .
