The weekend before each Thanksgiving, the symphony performs a children’s concert (“Tubby the Tuba” this year at The Schwartz Center), which is narrated to keep young minds focused, says player and business manager Cynthia Witt. The show also offers an instrument petting zoo so kids can familiarize themselves with the instruments. Proficient students can audition to play with the symphony, which gives valuable experience in learning group dynamics. Dover, 270-1903, doversymphony.org
