Alleluia is a choral arrangement of a famous melody from the third movement of one of Mozart's best-known works, the motet Exsultate, jubilate (K. 165). The third movement was originally scored in F Major for soprano and an orchestra comprised of two oboes, two horns, strings, continuo and organ. The editor has reduced this orchestration for keyboard and has added modern clefs as well as tempo and dynamic indications where appropriate. The source for this edition is W. A. Mozarts Samtliche Werke, Series 3/2, publlished by Breitkopf and Hartel (1876-1905)
