Photo courtesy Plateau Community Orchestra The Plateau Community Orchestra will perform its annual spring concert at 7:30 p.m. Tuesday in the Enumclaw High School auditorium. Musical selections will include two compositions written by Beethoven, a compilation of melodies from Mozart operas and an arrangement of familiar Italian melodies. Topping off the evening, concert-goers will be entertained by a rousing rendition of Sousa’s “Stars and Stripes” scored for orchestra. Admission is free, but donations at the door will be accepted. Under the direction of Lynda Alley Greer, the orchestra rehearses on Tuesday evenings in the Enumclaw Middle School band room. It is open to all age groups and skill levels. The only prerequisite is that members enjoy making music and having fun.
