In 1936, when Russian composer Sergei Prokofiev wrote Peter and the Wolf—a symphonic tale about a boy who defeats a nefarious four-legged—his aim was to introduce orchestral instruments and music to children. The narrated piece tells the story in both word and music, with a particular instrument and theme representing each character. For instance, strings represent Peter and French horns, the wolf. With the help of Roustabout Theater’s actors, the Santa Rosa Symphony will perform this 60-minute children’s symphony on January 26 at 3 p.m. at the Green Music Center in Rohnert Park. (At 2 p.m., there will be a free instrument petting zoo.) Tickets are $20 for adults, $10 for children ages 12 and younger, and may be purchased at srsymphony.org.
