The Piano Variations of American composer Aaron Copland were written for piano solo from January to October 1930. They were dedicated to American writer and literary critic Gerald Sykes (c. 1904–1984),[1] and were originally published in 1932 by Cos Cob Press, which merged with Arrow Music Press in 1938 and was taken over by Boosey & Hawkes in 1956. The approximate performance time is 11 minutes.
