Yodel-Ay-Ee-Oooo by Bart Plantenga (2003, Hardcover)

Yodel-Ay-Ee-Oooo is the first book to address the question: How did a centuries-old, Swiss mountain tradition make its way into American country music? Along the way, the reader discovers that yodeling is not just a Swiss thing--everyone from Central African pygmies, Nashville hunks-in-hats, avant-garde tonsil-twisters like Meredith Monk, hiphop stars De La Soul, and pop stars like Jewel have been known to kick back and release a yodeling refrain. Along the way, we encounter a gallery of unique characters, ranging from the legendary, such as country singer Jimmie Rodgers, to the definitely different, including Mary Schneider ("the Australian Queen of Yodeling") who specializes in yodeling Mozart, Beethoven, and Brahms, and the Topp Twins, a yodeling lesbian duo who employ the sound in their songs aimed at battling homophobia. The book is both a serious study of the history of yodeling around the world and a fun look at how this unique sound has worked its way into popular culture. Yodel-Ay-Ee-Oooo promises to be a classic for fans of music and popular culture.
