The term "choral symphony" refers to a work for orchestra and choir that typically involves large-scale musical forms and powerful vocal harmonies. However, there are several synonyms that can be used to describe this type of music. For instance, a "choral symphonic poem" is a similar work that is often characterized by a strong narrative or programmatic element. Another term that can be used to describe choral symphonies is a "cantata" or "oratorio," which are works for soloists, chorus, and orchestra that often have religious or operatic themes. Meanwhile, a "choral fantasia" is a work for choir and orchestra that is generally less formal than a choral symphony, but still has a strong vocal component.
