Poèmes symphoniques is a set of symphonic poems by Hungarian composer Franz Liszt, composed in the mid-19th century, primarily during the 1850s. They are single-movement orchestral works that employ programme-driven structures and expanded harmonic and orchestral techniques, reflecting Liszt's move from virtuosic piano writing to large-scale orchestral experimentation and helping to establish the symphonic poem as a distinct genre in 19th-century music.
