Each year, the San Francisco Opera Guild travels to 120 middle schools across the Bay Area working with students to put on a 45-minute adaptation of a traditional opera or operetta. This year’s production of “The Barber of Seville” features professional singers in ornate costumes, a pianist, and a docent – who weave a classic operatic story that includes students in the speaking roles. The artists coach students and rehearse with them, preparing them to perform the opera for the entire school. Pictured last month at Prestwood Elementary School were fifth-graders Soni Sherpa, Ruby Eilert, Ruby Sue Badgley and Dax Adams with performers from the Opera Guild.
