I don't know of any research; I base this statement purely on the intuition that piano shouldn't feel this natural to me. Typing itself could account for it, but I think Emacs has more piano-like dexterity requirements than typing in general. Another variable is that while I had't played the piano in a long time, I have done other musical things, and so just being a better, more experienced musician could also have an influence.
