Singers sing in recording studios or for live audiences in a variety of settings. Many professional singers have the ability to perform in a variety of styles like rock, classical, jazz, country, opera, or hip-hop. Though you can hear professional singers on the radio, you can also be a professional singer in a Broadway play, sing for commercial jingles, or even entertain on cruise ships. There is no one path to becoming a singer. However, performers of classical music and opera have at least a bachelor’s degree in music theory or a performance-based degree.
