Alleluia is a piece for unaccompanied SATB chorus by Randall Thompson. Composed over the first five days of July in 1940, it was given its world premiere on July 8 of that year at the Berkshire Music Center at Tanglewood under the direction of G. Wallace Woodworth. The text of the work consists of the word "Alleluia" repeated over and over again. The only other word in the text is "Amen", which is used once at the end. The end also divides the choir into seven parts. The piece has become Thompson's most popular work, and is frequently performed today.
