Jewel champions hillbilly culture for music career success

Grammy-nominated singer Jewel, who grew up on a farm in Alaska, says that learning to yodel as a child taught her "about vocal control and precision."

"I want my life to be my best work of art. I want to try to live thoughtfully and intentionally and sculpt my humanity into something that will please me at the end of my life."

She added, "At a gala for my Crystal Bridges [Museum] exhibit in the Ozarks [this year], I sang ‘Over the Rainbow’ and ended with a cappella yodeling. It was full circle – I wanted to honor the region and say, ‘Look what we hillbillies can do!’"
