the Chopin pieces for major ballet companies, including Maurice Ravel, Benjamin Britten, Alexander Gretchaninov, Roy Douglas, and Gordon Jacob. The Ravel orchestration has been lost. The Britten orchestration was considered lost but a score thought to be his was found in 2013 in the archives of the American Ballet Theatre. Roy Douglas's version has been recorded a number of times, and has largely supplanted the earlier versions. It was written in 1936, to replace what Douglas called "very bad orchestrations of Chopin's music".
