Maurice Duruflé (1902-1986) was an introspective and highly self-critical musician. As a result, he only published fourteen works in his lifetime. Ubi caritas, composed in 1960, is based on the Gregorian chant of the same name. The meditative text is set so that the freely flowing motion of the chant, first heard in the altos, is always at the forefront. It is primarily homophonic, with each voice moving together in hymn-like fashion.
