A duo concertante for violin, viola and piano This work was written around 1940, placing it near the beginning of a series of Clarke's late compositions. It both looks forward to her lean, linear, avowedly modern conceptions and backwards to works which are explicit homages to ancient styles, forms, and composers. A strain from the gypsy-rondo of Brahms's Piano Quartet Op. 25 echoes throughout the opening pages and is heard again in the piece's remarkable conclusion.
