I want to learn how to play the pinky G chord since it seems very useful to know for certain songs, but my pinky (on both my hands) does this weird thing where it doesn't bend into the place I want it to. Instead it gets to a certain point when I bend it and then snaps into the fully flexed position all of a sudden. I've had this as long as I can remember, but have never thought anything of it until playing guitar. Does anyone have any advice/techniques on how to manage this?
