General Sessions: Each day begins with Optimistic Voices, led by faculty as we learn a new song together. We'll enjoy instruction from faculty and quartet performances—including 2026 Queens of Harmony, Dynasty. Attendees will also gain insight during a panel discussion featuring Patty Cobb Baker, Peggy Gram, Mary Rhea, and Dynasty, moderated by QC Chair Karen Breidert. 

Strut Your Stuff Celebration: A Coronet Club tradition! We’ll close the event with emcee Karen Breidert leading this celebration of singing. Quartets are invited to sign up to perform. Karen will “draw names out of the crown,” giving quartets the chance to strut their stuff on stage!
