The Symphony No. 8 "Lieder der Vergänglichkeit" (Songs of Transience) by Krzysztof Penderecki is a choral symphony in twelve relatively short movements set to 19th and early 20th-century German poems. The work was completed and premiered in 2005. The symphony has an approximate duration of 35 minutes. Penderecki revised the symphony in 2007 by adding a few more poem settings and the piece has expanded to around 50 minutes. Although given the designation Symphony No. 8, it was not actually the final symphony Penderecki completed before his death in March 2020; the Sixth Symphony (subtitled "Chinese Songs"), begun in 2008, was not completed until 2017.
