A trombonist who couldn't hold back a sneeze during a church orchestra performance just let it fly directly into his instrument, producing one of the strangest sounds ever heard in classical music.

"If the band had been playing something loud and boisterous, it would have gone unnoticed," said London Central Band conductor Julian Bright, who was leading the orchestra during the incident.

Instead, the sneeze erupted during a quiet part of the piece, shocking the crowd. Bright thought "something in the PA system had blown up," he told the BBC.

Bright rates the aggressive-sounding trombone as the most unfortunate brass instrument to sneeze into.

"When you add a sneeze to the natural tendencies of the instrument, it's a lethal combination," he said.
