Rhapsody in Blue is a musical composition by George Gershwin for solo piano and jazz band written in 1924, which combines elements of classical music with jazz-influenced effects. The composition was orchestrated by Ferde Grofé three times, in 1924, in 1926, and finally in 1942. The piece received its premiere in a concert entitled An Experiment in Modern Music, which was held on February 12, 1924 , in Aeolian Hall, New York, by Paul Whiteman and his band with Gershwin playing the piano. The editors of the Cambridge Music Handbooks opined that "The Rhapsody in Blue (1924) established Gershwin's reputation as a serious composer and has since become one of the most popular of all American concert works."
Whether or not Rhapsody in Blue is "jazz" remains a much-debated topic. It should be noted that Whiteman styled himself "The King of Jazz". This appellation, applied to Whiteman's band of all-white musicians playing from written arrangements, would be questioned today, but in the 1920s, the word jazz was used loosely to cover a broad range of contemporary popular music.
