Rebecca Clarke wrote her monumental viola sonata in 1918/19, and it has since become a mainstay of the viola repertoire. The sonata is full of chromatic invention and utilises many viola effects such as pizzicatos and harmonics. While showing influences of Vaughan-Williams and Debussy, the piece is highly original and expertly written.
