I've been playing fingerstyle guitar for years and I'd been following the recommendation of many guitarists to anchor the picking hand by resting my pinky on the guitar top. However, this doesn't seem to be the preferred technique for flatpicking: I notice most flatpicking guitarists let their picking hand float over the strings without keeping any fingers anchored to the guitar top. My difficulty: in attempting to mimic this technique my picking hand feels a bit too "free", and I have trouble with accuracy as I speed up. Is this just a question of needing to practice more until I get more used to it? Or is there some way I should be resting my arm or wrist on the guitar that would make my picking hand feel more secure?
