Piano practice at 6am?

Being woken up at six to the kids arguing, watching the TV too loud, or simply having a kid tap you on the shoulder because they want something is painful. However when you get woken up at 6am to the piano being played it's absolutely delightful. It means whoever is playing is playing for themselves and not begrudgingly because you nagged them for an hour. Music played at dawn is even more sweet when it wafts up to your sleeping ears.
