Requiem

Requiem in D minor, K.626, is a requiem mass by Austrian composer Wolfgang Amadeus Mozart, composed in 1791. The choral-orchestral work combines Classical-period harmonic language with dramatic, operatic vocal writing and sombre orchestration, and it was left unfinished at Mozart's death and subsequently completed by others, placing it as his final major composition and a key work in the late-18th-century sacred repertoire.
