- I Got Rhythm is a 1930 song composed by George Gershwin with lyrics by Ira Gershwin, published in 1930.
- It originally appeared in the musical Girl Crazy, after an earlier slower version was written for Treasure Girl (1928).
- The piece was first sung on Broadway by Ethel Merman in the original production.
- The tune was written in D-flat major and uses four notes of the pentatonic scale, with syncopation that sits behind the main pulse.
- Its rhythm changes, a famous 32-bar progression, became the foundation for many jazz tunes, and the chorus is in a 34-bar AABA form.
- I Got Rhythm quickly became a jazz standard and a symbol of the Gershwins and the 1920s swing era; it inspired the 1934 piano and orchestra piece Variations on I Got Rhythm.
- The song has appeared in films such as An American in Paris (1951) with Gene Kelly, and has been widely recorded by artists including The Happenings, Judy Garland, and Ella Fitzgerald.
