Very interesting. I have been impressed on several occasions when I have heard my son tapping out a rhythm in time to some music playing in the room. I first noticed this when he was around two. Likewise I have been impressed with my daughters pitch when singing along to music in the car, quietly. In both cases, they were unaware that anyone was paying attention.
On the other side of it and to support Bob's statement, when called upon to do the same while being directly observed, the results were quite different.
