Can anyone please tell me how some folks can jam to songs they dont even know??? I can chop or play single notes here and there if I know what key they are in.(they will usually say) Like: Key of A. I know it will most likely be A…D….E. But some people just move quickly up and down the strings. I try to follow but by time I get to where they are at they are long gone onto the next part of the song. Grrrrrr I tell myself not to get discouraged and I admire folks who play off the cuff. But when I ask how they know where to go they usually just say “I dont know, I just play” Really???? What kind of answer is that?
