Dance Panels is a ballet composed by Aaron Copland in 1959 for a planned collaboration with choreographer Jerome Robbins.
 After Copland had written the score, Robbins reneged on his commitment and the performance did not take place.
 Three years later, Copland revised the score for a ballet by the Bavarian State Opera in Munich, Germany, where it premiered on 3 December 1963.
 The ballet was performed by the New York City Ballet in 1965 and the concert version received its first performance at the Ojai Music Festival the following year.
 According to Copland biographer Howard Pollack, "Dance Panels" has proven from a musical standpoint one of the composer's more accessible late scores.
 While some of its more dissonant moments sound similar to Copland's 12-tone compositions, other parts recall his earlier stage and screen music.
 It is also the only one of Copland's six ballets not written to a specific program.
Cesare Pugni (Russian: Цезарь Пуни ) (] ; 31 May 1802–26 January [O.S. 14 January] 1870 ) born in Genoa, was an Italian composer of ballet music, a pianist and a violinist.

 Pugni is most noted for the ballets he composed for Her Majesty's Theatre in London (1843–1850), and for the Imperial Theatres in St. Petersburg, Russia (1850–1870).
 The majority of his ballet music was composed for the works of the ballet master Jules Perrot, who mounted nearly every one of his ballets to scores by Pugni.
 In 1850 Perrot departed London for Russia, having accepted the position of "Premier maître de ballet" of the St. Petersburg Imperial Theatres at the behest of Carlotta Grisi, who was engaged as "Prima ballerina".
 Cesare Pugni followed Perrot and Grisi to Russia, and remained in the imperial capital even after Grisi's departure in 1853 and Perrot's departure in 1858.
 Pugni went on the compose for Perrot's successors Arthur Saint-Léon and Marius Petipa, serving as the Imperial Theatre's official composer of ballet music until his death in 1870.

Erik William Chisholm (4 January 1904 – 8 June 1965) was a Scottish composer, pianist, organist and conductor sometimes known as "Scotland's forgotten composer".
 According to his biographer, Chisholm "was the first composer to absorb Celtic idioms into his music in form as well as content, his achievement paralleling that of Bartók in its depth of understanding and its daring", which led some to give him the nickname "MacBartók".
