An American in Paris is a jazz-influenced symphonic poem by the American composer George Gershwin, written in 1928. Inspired by the time Gershwin had spent in Paris, it evokes the sights and energy of the French capital in the 1920s and is one of his best-known compositions.
Gershwin composed An American in Paris on commission from the conductor Walter Damrosch. He scored the piece for the standard instruments of the symphony orchestra plus celesta, saxophones, and automobile horns. He brought back some Parisian taxi horns for the New York premiere of the composition, which took place on December 13, 1928 in Carnegie Hall, with Damrosch conducting the New York Philharmonic. Gershwin completed the orchestration on November 18, less than four weeks before the work's premiere.
Gershwin collaborated on the original program notes with the critic and composer Deems Taylor, noting that: "My purpose here is to portray the impression of an American visitor in Paris as he strolls about the city and listens to various street noises and absorbs the French atmosphere." When the tone poem moves into the blues, "our American friend ... has succumbed to a spasm of homesickness." But, "nostalgia is not a fatal disease." The American visitor "once again is an alert spectator of Parisian life" and "the street noises and French atmosphere are triumphant."
Maurice Ravel met Gershwin in New York during Ravel's tour of the United States. In that meeting, Gershwin asked Ravel to be his teacher, to which Ravel responded that it was better to be a first-rate Gershwin than a second-rate Ravel. Instead, Ravel recommended that Gershwin see Nadia Boulanger in Paris. Ravel's high praise of Gershwin in an introductory letter to Boulanger caused Gershwin to seriously consider taking time to study abroad in Paris.
Gershwin arrived in Paris in March 1928. Paris at this time hosted many expatriate writers: among them Ezra Pound, W. B. Yeats, Ernest Hemingway; and artist Pablo Picasso. Gershwin met with Boulanger and at her request he played ten minutes of his music. Boulanger replied that she had nothing to teach him. This did not set Gershwin back, as his real intent abroad was to complete a new work based on Paris and perhaps a second rhapsody for piano and orchestra to follow his Rhapsody in Blue.
Gershwin based An American in Paris on a melodic fragment called "Very Parisienne", written in 1926 on his first visit to Paris as a gift to his hosts, Robert and Mabel Schirmer. He described the piece as a "rhapsodic ballet" because it was written freely and is more modern than his previous works. Gershwin explained in Musical America, "My purpose here is to portray the impressions of an American visitor in Paris as he strolls about the city, listens to the various street noises, and absorbs the French atmosphere."
The piece is structured into five sections, which culminate in a loose ABA format. Gershwin's first A episode introduces the two main "walking" themes in the "Allegretto grazioso" and develops a third theme in the "Subito con brio". The style of this A section is written in the typical French style of composers Claude Debussy and Les Six. This A section featured duple meter, singsong rhythms, and diatonic melodies with the sounds of oboe, English horn, and taxi horns. The B section's "Andante ma con ritmo deciso" introduces the American Bluesand spasms of homesickness. The "Allegro" that follows continues to express homesickness in a faster twelve-bar blues. In the B section, Gershwin uses common time, syncopated rhythms, and bluesy melodies with the sounds of trumpet, saxophone, and snare drum. "Moderato con grazia" is the last A section that returns to the themes set in A. After recapitulating the "walking" themes, Gershwin overlays the slow blues theme from section B in the final “Grandioso.”
An American in Paris is scored for 3 flutes (3rd doubling on piccolo), 2 oboes, English horn, 2 clarinets in B flat, bass clarinet in B flat, 2 bassoons, 4 horns in F, 3 trumpets in B flat, 3trombones, tuba, timpani, snare drum, bass drum, triangle, wood block, cymbals, low and high tom-toms, xylophone, glockenspiel, celesta, 4 taxi horns labeled as A, B, C and D, alto saxophone/soprano saxophone, tenor saxophone/soprano saxophone/alto saxophone, baritone saxophone/soprano saxophone/alto saxophone, and strings.
The revised edition by F. Campbell-Watson calls for three saxophones, alto, tenor and baritone. In this arrangement the soprano and alto doublings have been rewritten to avoid changing instruments.
William Daly arranged the score for piano solo which was published by New World Music in 1929.
Gershwin did not particularly like Walter Damrosch's interpretation at the world premiere of An American in Paris. He stated that Damrosch's sluggish, dragging tempo caused him to walk out of the hall during a matinee performance of this work. The audience, according to Edward Cushing, responded with "a demonstration of enthusiasm impressively genuine in contrast to the conventional applause which new music, good and bad, ordinarily arouses." Critics believed that An American in Paris was better crafted than his lukewarm Concerto in F. Some did not think it belonged in a program with classical composers César Franck, Richard Wagner, or Guillaume Lekeu on its premiere. Gershwin responded to the critics, "It's not a Beethoven Symphony, you know... It's a humorous piece, nothing solemn about it. It's not intended to draw tears. If it pleases symphony audiences as a light, jolly piece, a series of impressions musically expressed, it succeeds."
On September 22, 2013, it was announced that a musicological critical edition of the full orchestral score will be eventually released. The Gershwin family, working in conjunction with theLibrary of Congress and the University of Michigan, are working to make scores available to the public that represent Gershwin's true intent. It is unknown if the critical score will include the four minutes of material Gershwin later deleted from the work (such as the restatement of the blues theme after the faster 12 bar blues section), or if the score will document changes in the orchestration during Gershwin's composition process. 
The score to An American in Paris is currently scheduled to be issued first in a series of scores to be released. The project may take 30 to 40 years to complete. The first edition will probably be published by 2023.  
An American in Paris has been frequently recorded. The first recording was made for RCA Victor in 1929 with Nathaniel Shilkretconducting the Victor Symphony Orchestra, drawn from members of the Philadelphia Orchestra. Gershwin was on hand to "supervise" the recording; however, Shilkret was reported to be in charge and eventually asked the composer to leave the recording studio. Then, a little later, Shilkret discovered there was no one to play the brief celesta solo during the slow section, so he hastily asked Gershwin if he might play the solo; Gershwin said he could and so he briefly participated in the actual recording. The radio broadcast of the September 8, 1937 Hollywood Bowl George Gershwin Memorial Concert, in which An American in Paris, also conducted by Shilkret, was second on the program, was recorded and was released in 1998 in a two-CD set. Arthur Fiedler and theBoston Pops Orchestra recorded the work for RCA Victor, including one of the first stereo recordings of the music. In 1945, Arturo Toscanini and the NBC Symphony Orchestra recorded the music in Carnegie Hall, one of the few commercial recordings Toscanini made of music by an American composer. The Seattle Symphony also recorded a version in 1990 of Gershwin's original score, before he made numerous edits resulting in the score as we hear it today. 
In 1951, MGM released the musical An American in Paris, featuring Gene Kelly and Leslie Caron. Winning the 1951 Best Picture Oscar and numerous other awards, the film was directed by Vincente Minnelli, featured many tunes of Gershwin, and concluded with an extensive, elaborate dance sequence built around the An American in Paris symphonic poem (arranged for the film by Johnny Green), costing $500,000.
A part of the symphonic composition is also featured in As Good as It Gets, released in 1997
