Earlier this week, a live performance of the music of Mozart left an audience in a concert hall completely speechless. Right in the middle of the performance, a moment went viral in which an awestruck child could not help but exclaim “wow” as the beautiful music played.

The Handel and Haydn Society was performing their live orchestra season finale so that it could be recorded and aired on WCRB radio in the fall. Just when they were finishing the last notes of Mozart’s Masonic Funeral Music, a young child could be heard saying “Wow!” After hearing this exclamation, the audience could not help but applaud in agreement!

Once the concert was over, Handel and Haydn Society President David Snead wrote an open letter to the audience asking them to help identify who the youngster was.

“At the end of Sunday’s performance … something happened that I had never before experienced in my 40+ years of concert-going,” wrote Snead. “While Harry Christophers was holding the audience rapt in pin-drop silence following the music’s end, what sounded like a child of about six years of age couldn’t hold back and gave out a ‘Wow!’ heard round the hall.”

“We would like to give our newest H+H fan and his family a copy of the recording and invite them to meet Harry Christophers when he returns to Boston this fall,” he continued. “H+H has great respect for our audience’s privacy and all information will be kept confidential in accordance with the family’s wishes. Regardless, it was one of the most wonderful moments I’ve experienced in the concert hall, and I’m glad you were all there to experience it as well.”
