"Over the Rainbow" (often referred to as "Somewhere Over the Rainbow") is a classic ballad song with music by Harold Arlen and lyrics by E.Y. Harburg. It was written for the movie The Wizard of Oz, and was sung by Judy Garland in that movie. Over time it would become Garland's signature song.In the film, part of the song is played by the MGM orchestra over the opening credits. About 20 minutes later, Garland, in the role of Dorothy, sings Over the Rainbow after unsuccessfully trying to get her aunt and uncle to listen to her regarding an unpleasant incident involving Dorothy's dog Toto and the nasty spinster Miss Gulch, whom Toto bit after she struck him with a rake. Dorothy's Aunt Em tells her to "find a place where you won't get yourself into any trouble", prompting the girl to walk off by herself and sing the song.
