Question for the musically inclined

How normal is it for a 7 year old girl to pick up a set of cheap plastic pan pipes she got with an Easter egg and, within an hour, with no tuition, music, or help, be playing a recognisable version of Ode To Joy amongst other tunes?

Seriously, we've never taught her to play anything and she's taught herself Beethoven on something she only got given this afternoon.

This isn't normal, right?
