Have you heard of this guy yet?
"We are talking about a prodigy of the level of the greatest prodigies in history when it comes to composition," says Sam Zyman, a composer. "I am talking about the likes of Mozart, and Mendelssohn, and Saint-Sans."
Zyman teaches music theory to Jay at the Juilliard School in New York City, where he’s been teaching for 18 years.
"This is an absolute fact. This is objective. This is not a subjective opinion," says Zyman. "Jay could be sitting here, and he could be composing right now. He could finish a piano sonata before our eyes in probably 25 minutes. And it would be a great piece."
