More than 100 voices in harmony carried a St. Charles barbershop chorus to its 6th championship

Ambassadors of Harmony, a barbershop chorus from St. Charles, won its sixth national championship earlier this month at the International Chorus Contest. Brothers and performers Jonny and Blake Moroni share their reactions to the win and the collaborative effort that created the chorus' winning arrangement of "Muskrat Ramble," which adapted a jazz standard into a massive performance involving more than 100 singers. Jonny Moroni also leads a special demonstration of how a championship-winning chorus “builds” a harmony, voice by voice.
