franz schubert's symphony no. 8 in b minor, d 759 (sometimes renumbered as symphony no. 7, in accordance with the revised deutsch catalogue and the neue schubert-ausgabe), commonly known as the unfinished symphony (), is a musical composition that schubert started in 1822 but left with only two movements—though he lived for another six years. a scherzo, nearly completed in piano score but with only two pages orchestrated, also survives.
