Local members of Harmony on the Sound Chorus — a chapter of Sweet Adelines International — came to Town Hall June 21 to sing to the First Selectman and a small audience of town employees. Under the direction of Master Director Karen Sweeters, the group sings a cappella four-part barbershop style harmony. They gave the audience a lesson on four-part harmony and sang songs like “Under the Boardwalk” and “Heartache Tonight.” Members who performed hail from Trumbull and other towns in Fairfield County.
