Aaron Copland wrote his rarely-heard ballet Hear Ye! Hear Ye! for Ruth Page, the dancer and choreographer who was to become the Grande Dame of American ballet. Its scenario is a murder in a nightclub and the ensuing trial in a Chicago courtroom. Copland infused the score with the spirit of his jazz-influenced pieces, controversially distorting part of the National Anthem, and infiltrating music from some of his earlier works. In complete contrast, Appalachian Spring is his most famous work, a true American masterpiece founded on transfigured dance tunes and song melodies.
