If a singer isn’t currently booked into an opera, that doesn’t mean they can afford to take time off. Opera singing is completely entrepreneurial, which means you must constantly be auditioning for new parts. Opera singers without current gigs spend their days taking voice lessons, practicing for recitals, attending performances, and learning musical pieces to use in future shows. Film actors, on the other hand, may work on location or in studios. On location shoots may take place in a variety of settings, from city streets to remote wilderness areas. Actors must be able to adapt to different environments and work in challenging conditions, such as extreme temperatures or long hours.
