How is the tone poem different from a program symphony?

Answer 1

One movement orchestral work. Different instruments represented the characters. The structural elements in a symphony were largely free of classic predictability.

Answer 2

A tone poem is a single-movement orchestral work that expresses a specific idea or story through music, typically symphonic in form but with more flexibility in structure and content than a traditional symphony. A program symphony, on the other hand, is a multi-movement orchestral work where each movement represents a different aspect of a program or story, typically unified by a common theme or narrative thread running through the entire piece.
