The Princeton Symphony Orchestra’s BRAVO! education program presented “The Sky is the Limit!” to more than, students from about two dozen area schools on May 10. Paul Chapin, interim president of Riverside Elementary School, surprised his students when he took to the stage to narrate Daniel Dorff’s work “Blast Off,” complete with countdown. “Performing Daniel Dorff’s piece in front students I teach, sitting on the front of the stage with the orchestra behind and seeing the students’ faces light up as they recognize pieces they’ve studied—how exciting and wonderful!,” Chapin said.
