When I was younger I learned somewhere over the rainbow on the ukulele in music class and we watched the Israel Kaʻanoʻi Kamakawiwoʻole, music video. Somewhere over the Rainbow to me is a very relaxing and calming song that is typically played in warmer more tropical areas and not in Wisconsin. Israel’s Somewhere over the Rainbow music video was set in Hawaii and it was very relaxing with the ukulele playing and then watching the pictures made me wish I was somewhere warm. However, I found a cover of Somewhere of the Rainbow being played on steel drums, which just made it more relaxing and gave me a more tropical feeling.
