In 1966, members of the chorus of the Boulder Civic Opera decided to become a separate entity, available to the Opera for performances, but also rehearsing and performing independently. The group consisted of five sopranos, five altos, and three men. And that was the start. Now in our 51st year, the Boulder Chorale is inter-generational. Over 200 singers aged 5 to 88 perform in six ensembles at free concerts, high-profile community events, and traditional concert venues.
