Last week, we reported that the concert world was on the hunt for a child who exclaimed “Wow!” during an orchestral performance of a Mozart piece. Now, that child has finally been identified as a 9 year-old boy with autism.

Little Ronan Mattin had attended the Handel and Haydn Society’s performance of Mozart’s Masonic Funeral Song in Boston with his grandfather Stephen Mattin when his charming reaction to the music went viral. Afterwards, Handel and Haydn Society President David Snead penned an open letter in which he called the child’s reaction “one of the most wonderful moments he had experienced in the concert hall.”

When Stephen saw how much joy his grandson’s reaction was giving people, he was absolutely delighted. He explained that since Ronan has autism, he is not often vocal about his feelings, which makes this whole thing all the more special to his family.

“I can count on one hand the number of times that [he’s] spontaneously ever come out with some expression of how he’s feeling,” Stephen said. “You know, everybody’s different. Everybody has different ways of expressing themselves. I think people in general, society’s becoming more tolerant or understanding of the differences between people.”

The Mattin family is now working with staffers with the Handel and Haydn Society to set up a meet-and-greet between Ronan and the conductor in the fall. We’re so glad that this little boy has been identified, and we hope that this is just the beginning of many more magical musical moments for him!
