I would say B any chord, but, my teacher is pushing them and I am getting a tad better. However, I'm with Zurf on F#m, it is hard and I can do without it. THough one of my favorite Jim Croce songs has it. Oy I muddle thru. My biggest challenge is a rapid transition from G to F and back to G on the traditional folk tune "Ground Hog." Then my fret hand develops major spasms and it's all I can do to keep up with the rest of the String Band class. OY
Now if there was only something I could do about the "Brain Worms" that I get whenever we play this and certain other folk tunes for long durations.
Brain Worms......the song that gets stuck in your head and you can't get it out!!
Use the barre G. It's the same shape as F but up two frets. Then all you have to do is relax your hand, slide up two frets, and retension your fingers.
G to F to G becomes much easier with the barre, even though barres aren't fun they're funner than G to F to G without them. Is funner a word?
Maybe there's a deworming pill like dogs get for heartworms to help with your other problem.
