"Over the Rainbow" (often referred to as "Somewhere Over the Rainbow") is a classic Academy Award-winning ballad song with music by Harold Arlen and lyrics by E.Y. Harburg. It was written for the 1939 movie, The Wizard of Oz, and was sung by actress Judy Garland in her starring role as Dorothy Gale. Over time, it would become Garland's signature song.
About five minutes into the film, actress Judy Garland, playing the lead character, Dorothy, sings "Over the Rainbow" after unsuccessfully trying to get her aunt and uncle to listen to her relate an unpleasant incident involving her dog, Toto, and the town spinster, Miss Gulch (Margaret Hamilton). Dorothy's Aunt Em tells her to "find yourself a place where you won't get into any trouble", prompting Dorothy to walk off by herself. She muses to Toto "'Someplace where there isn't any trouble.' Do you suppose there is such a place, Toto? There must be. It's not a place you can get to by a boat, or a train. It's far, far away. Behind the moon, beyond the rain.....", and begins singing the song.
