I recently heard that the nerves controlling the pinkie and ring finger are intertwined to the degree that it’s almost impossible for most people to move the pinkie and ring fingers without the other. Does it count as “independent” if one twitches while the other does the real moving? I think I may finally be special!
To learn to play guitar I had to get my fingers to move more independently. Difficult at first but you can do it. I assume it is similar for other stringed instruments.
