Well, now, in our "gma" studios, we have somebody who is ready to give you a special perform manse right here on this piano. The one that pea jana's making me hide behind. They call him minimozart. And baby beethoven. You're going to see him play in a minute. But quick, we're going to take a first look at how he stunned his parents with his talent. His feet don't reach the pedals. His fingers are barely able to stretch across the keys. But that does not stop 5-year-old jacob velazquez from playing a mean piano. This minimozart started playing the piano a year ago. And learned beethoven's sonata in just three weeks. Even jacob's mom was surprised by her son's ivory-tickling talent. The first time she heard him play, she thought it was her husband in the other room. Is that jacob? Oh, my gosh. Reporter: Turns out, jacob has a photographic memory. His music teacher says he is able to master songs in just one class that most children take a month to learn. Handel. Reporter: He recently auditioned for the national musicians guild. A performance his dad says he nailed, right away. He had to learn ten classical pieces, by memory. And he did. He did great. Exceeded the expectations. Reporter: Move over beethoven. This pint-sized pianist, is here to play. I said, who is that handsome guy? He said, me. He has a good sense. We're happy to have jacob here in the studio. Along with parents, tina and willie. We were talking before the show. You were saying not long ago, your son was diagnosed with high-functioning autism. And that playing the piano has helped. Definitely. He definitely expresses himself. He is an outlet for him. Sometimes I notice he'll play really fast if he's anxious. He'll start playing really fast. If he's angry. He plays low-key. He plays very hard. He's demonstrating. It's an outlet for him. Jacob, while dan was talking you're so anxious, you're ready to start playing. So, take it away. Go. ♪ ♪
