The music to Somewhere over the Rainbow was written by Harold Arlen; the lyrics were written by Edgar Yipsel (Yip) Harburg. But Julie Garden sang it. Arlen and Harburg collaborated on all the songs featured in the movie, The Wizard of Oz. Over the Rainbow won Academy awards for them both.

We are gradually brought towards the moment when âeverything was rainbow, rainbow, rainbowâ and the beautiful simplicity of the ending when she decides to let the fish go.
