A symphonic poem is a piece of orchestral music that tells a story or conveys a specific idea, emotion, or scene. Unlike traditional symphonies, which follow a structured format, symphonic poems are often free in form and can vary in length. They aim to evoke imagery and feelings through musical themes and motifs. The concept of the symphonic poem was popularized in the 19th century by composers like Franz Liszt. These works often draw inspiration from literature, art, or nature, allowing listeners to experience a narrative or concept purely through sound. Symphonic poems remain a significant part of the orchestral repertoire today.
