Charles Wuorinen composed his virtuosic "Viola Variations" in 2008 for Lois Martin. Elliott Carter also wrote several works for viola including his "Elegy" (1943) for viola and piano; it was subsequently transcribed for clarinet. Ernest Bloch, a Swiss-born American composer best known for his compositions inspired by Jewish music, wrote two famous works for viola, the "Suite 1919" and the "Suite Hébraïque" for solo viola and orchestra. Rebecca Clarke was a 20th-century composer and violist who also wrote extensively for the viola. Lionel Tertis records that Edward Elgar (whose cello concerto Tertis transcribed for viola, with the slow movement in scordatura), Alexander Glazunov (who wrote an "Elegy", Op. 44, for viola and piano), and Maurice Ravel all promised concertos for viola, yet all three died before doing any substantial work on them.
