Orchestras take on Broadway music scores that are composed for symphonies. Popular ones include "The Lion King," "Beauty and the Beast," "West Side Story" and "Fiddler on the Roof."
Film music is played by orchestras as well. The music of "Star Wars," Disney movie medleys, and "Titanic" have all been performed by orchestras.
