I'm sure you already know that each of these keys plays a different note, and that the smaller keys up top represent the sharp and flat variations on those same seven notes, so I'm sure I don't need to start at the very basics. [because that's common sense and everyone should know that]

Starting with how to properly hold your hands while playing should suffice, I'd say. You can't simply lay your hands on the keys and expect it to sound nice while played. You have to position them like so in order to be able to reach certain notes and create certain chords to play properly. [resting his hands on the keys in the PROPER way okay. It's just natural for him at this point. Now it's your turn, Hungary]
