When I was learning to play guitar, I didn't think I would ever master transitioning from one chord to another. I always had to stop and move my fingers, then start playing again. How can you even do that? How can you reposition your fingers in zero time? 

But I kept practicing and then one day I had the idea of moving my fingers just before the transition....that's the thing - you have to do something different from what the music seems to require. Drumming is like that, as is singing and playing guitar at the same time. 

That was pretty much it...once I started moving my fingers slightly before the transition, I had it.
