The Ambassadors of Harmony (AOH) is a 120+ member men's barbershop chorus, based in St. Charles, Missouri. The chorus won International Championship gold medals in 2004, 2009, and 2012 – each time singing two arrangements by David Wright, under the direction of Dr. Jim Henry – and then again in 2016, under the co-direction of Jonny Moroni and Dr. Henry. Their 2009 victory broke a nearly three-decade winning streak by the Vocal Majority.
