Lacrymosa (song)

"Lacrymosa" is a song by American rock band Evanescence from their second studio album, The Open Door (2006). The song was composed by singer and pianist Amy Lee and guitarist Terry Balsamo, with production by Dave Fortman and choral arrangements by Lee. It incorporates the Lacrimosa sequence from Mozart's Requiem (1791), which was originally performed in the key of D minor and transposed into E minor for the song.

Lee, a David Campbell–led orchestra, and a choir recorded "Lacrymosa" at a chapel in Seattle, Washington. The song contains elements of several genres, including classical music, gothic rock, progressive rock, and industrial rock. "Lacrymosa" garnered generally positive reviews from music critics, who praised Lee's vocals and arrangement and deemed it one of the most memorable songs on The Open Door. An alternate version appears on the band's fourth studio album Synthesis (2017).
