Whoa! Wait a minute! If this kid is "taking dictation" from what he hears in his head, he's exactly like Mozart, who did the same thing. Mozart's original scores show very few, if any, corrections. He wrote the music down completely, as he heard it in his head, and then he was done with it. There were never any rough drafts or final copies. The talents of this kid are very believable - we just haven't seen it in over 200 years. And if people don't "get" his music at this point in time, that's okay; they didn't "get" Mozart's when it was new, either: "too many notes!", was the line I remember from Amadeus.
Brian Wilson has the same gift. 200 years my butt.
Philippa Schuyler?
