I'm pondering what a "Supernatural piano" might be. The kind of pianos they have in heaven? A ghost piano? A piano that plays itself? (No wait, they already have those, and this one may well do it too.)
And that child's hand position really leaves something to be desired (look closely). Who's his teacher? Better to send him to me right away, before it's too late.
