Aaron Copland wrote the Symphony for Organ and Orchestra in 1924.[1] It represents a major work in the composer's oeuvre, as it was his first fully realized orchestral work, his first work for organ, and the first piece whose orchestration he heard. It was premiered on January 11, 1925, in New York. In 1928, Copland re-orchestrated the work without organ as his Symphony No. 1, rewriting the organ part in the brass and adding saxophone.[2]
