Wolfgang Amadeus Mozart's Ave verum corpus in D major (K. 618) was written for Anton Stoll (a friend of his and Joseph Haydn's) who was musical co-ordinator in the parish of Baden bei Wien, near Vienna. This setting of the Ave verum corpus text was composed to celebrate the feast of Corpus Christi and the autograph is dated 17 June 1791. It is only forty-six bars long and is scored for SATB choir, stringed instruments, and organ. Mozart's manuscript itself contains minimal directions, with only a single sotto voce at the beginning.
Mozart composed this motet while in the middle of writing his opera Die Zauberflöte, and while visiting his wife Constanze, who was pregnant with their sixth child and staying in a spa near Baden. It was less than six months before Mozart's death. The motet foreshadows "aspects of the Requiem such as declamatory gesture, textures, and integration of forward- and backward-looking stylistic elements."
Franz Liszt quotes Mozart's motet in the piano piece Evocation à la Chapelle Sixtine.Pyotr Ilyich Tchaikovsky incorporates an orchestration of Liszt's transcription in his fourth orchestral suite, Mozartiana.
