George Gershwin was one of the most successful composers of the time with an unusual background. Born into a family of migrants without a musical tradition, he made his first steps as a song-plugger and piano-roll pianist for the publishing house Remick's. Gershwin's style stands out from the traditional frames of classical music composers, and his compositions like The American in Paris, Rhapsody in Blue, the opera Porgy and Bess and various songs from his musicals, such as Summertime, I Got Rhythm, The Man I Love, 's Wonderful today are performed as a complete piece or the musicians use just the themes as a foundation and inspiration for a jazz improvisation.

Smotuljak papira kretao bi se pomoću vakuuma uz pritisak pedala ili uz korištenje električne energije prilikom čega bi pijanist svojom izvedbom stvarao perforacije u papiru označavajući detalje o noti: njezino trajanje i tonsku visinu. Prilikom pokretanja reprodukcijskog klavira, smotuljak papira se kreće preko metalnog sistema za čitanje te perforacije postaju okidač za izvođenje zapisa. 3 U nastavku će se ponegdje javiti skraćeni oblik naziva djela kao Rapsodija. 2 important Gershwin's composition, and the context of the creation and orchestration of Rhapsody, as well as a deeper look into its musical structure are the main part of this work.
