Curlew River – A Parable for Church Performance (Op. 71) is an English music drama, with music by Benjamin Britten to a libretto by William Plomer. The first of Britten's three 'Parables for Church Performance', the work is based on the Japanese noh play Sumidagawa (Sumida River) of Juro Motomasa] (1395–1431), which Britten saw during a visit to Japan and the Far East in early 1956. Beyond the noh source dramatic material, Britten incorporated elements of noh treatment of theatrical time into this composition. Curlew River marked a departure in style for the remainder of the composer's creative life, paving the way for such works as Owen Wingrave, Death in Venice and the Third String Quartet.
