Tulsa Youth Symphony, one of the city's oldest arts organizations, presents two performances of a 45-minute concert for children. The concert is designed for young people from pre-school through the elementary grades, although the music will appeal to all ages. A booklet with musical activities, as well as information about the music and the orchestra, will be given to each young person attending. The program will consist of demonstrations of individual instruments and sections of the orchestra as well as compositions that stimulate the imagination. Selections include "Star Wars," "Night on Bald Mountain," "The Wasps" and "Scheherazade." Pencil batons and a quick conducting lesson will be provided, and a "guest conductor" will be chosen from the audience.
