The "Lacrymosa" is one of the most poignant movements of Mozart's unfinished Requiem in D minor (K. 626), composed in 1791 — the year of his death — and completed posthumously by Franz Xaver Süssmayr. The 8-bar fragment Mozart left behind, with its lamenting 12/8 rhythm and rich choral writing, remains one of the most emotionally powerful pieces in the Western choral canon.
