The accordion is a box-shaped musical instrument of the bellows-driven free-reed aerophone family, sometimes colloquially referred to as a squeezebox. A person who plays the accordion is called an accordionist.

The instrument is played by compressing or expanding the bellows whilst pressing buttons or keys, causing valves, called pallets, to open, which allow air to flow across strips of brass or steel, called reeds, that vibrate to produce sound inside the body.

This instrument is sometimes considered a one-man-band, as it needs no accompanying instrument. The performer normally plays the melody on buttons or keys on the right-hand manual, and the accompaniment, consisting of bass and pre-set chord buttons, on the left-hand manual.

The accordion is often used in folk music in Europe, North America and South America and in some countries, such as in Brazil, it is also commonly used in mainstream pop music. In Europe and North-America, it is often associated with busking. Some popular music acts also make use of the instrument. Additionally, the accordion is sometimes used in both solo and orchestra performances of classical music.

George Gershwin (September 26, 1898 – July 11, 1937) was an American composer and pianist. Gershwin's compositions spanned both popular and classical genres, and his most popular melodies are widely known. Among his best known works are the orchestral compositions Rhapsody in Blue and An American in Paris, as well as the opera Porgy and Bess.

Born in Brooklyn to a Ukrainian father of Jewish descent and a Russian mother, Gershwin studied piano under Charles Hambitzer and composition with Rubin Goldmark and Henry Cowell. He began his career as a song plugger, but soon thereafter started composing Broadway theatre works with his brother Ira Gershwin and Buddy DeSylva. He moved to Paris in an attempt to study with Nadia Boulanger, where he began to compose An American in Paris. After returning to New York City, he wrote Porgy and Bess with Ira and author DuBose Heyward. Initially a commercial failure, Porgy and Bess is now considered one of the most important American operas of the Twentieth Century. Gershwin moved to Hollywood and composed numerous film scores until his death in 1937 from a brain tumor.
