Final answer:
The symphonic poem typically has a narrative structure and is often inspired by literature, but does not typically have vocal elements and is composed as a single movement.
Step-by-step explanation:
The symphonic poem, a form of orchestral composition popularized by Franz Liszt, is characterized by several key features. It typically has a narrative structure, meaning it tells a story or depicts a specific event or idea. It is often inspired by literature, drawing on literary works or themes for inspiration. However, it typically does not have vocal elements. Instead, it is composed for instruments only, allowing the music to convey the emotions and images represented in the piece. Finally, the symphonic poem is composed as a single movement, rather than being divided into multiple movements like a symphony.
