Defining Gershwin rhapsody was conceived on a train trip
Disney's Rhapsody In Blue
Rhapsody in Blue is one of the most performed of all American concert pieces, and its opening clarinet glissando is the most recognized jazz passage.
George Gershwin first found out he was meant to be writing his most innovative work from a newspaper point. Legend has it that Gershwin absolutely forgot that Whiteman (orchestral director) had commissioned a piece from him for the upcoming concert in New York. Gershwin had only five weeks left before the premiere.
He began composing the new concerto immediately. Because he needed to travel to Boston, the main part was written on the train. The composer later claimed:
"It was on the train, with its steely rhythms, its rattle-ty bang that is often so stimulating to a composer (I frequently hear music in the very heart of noise) that I suddenly heard—and even saw on paper—the complete construction of the Rhapsody from beginning to end".
What Gershwin produced was not a “jazz concerto” but a rhapsodic work for “piano and jazz band” including details of European symphonic music and American jazz with its supreme melodic movement and keyboard facility.
The Rhapsody, with its composer as soloist, was premiered in front of a packed house that included such personalities as Rachmaninov, the violinist Fritz Kreisler and the conductor Leopold Stokowski.
