All fingers are doing as requested, but that index finger is just laying down laterally to the far left. In other words, the tip of that finger is not on the string. Even if I physically lift it up to stay up straight, it just drops back down onto its side :(
If anyone else here has had this problem and overcame it, please let me know how.
I thought the F chord was going to be a difficult one, and yet I can get it working 60% of the time, which is good because I can keep practising and it will improve, but that B major!
All I can think of doing for now is to try to stretch the index finger side ways so that it has more flexibility to stay up straight.
