A Swiss university now offers a degree in yodeling. The Lucerne University of Applied Sciences and Art is will soon offer bachelors and masters degrees in the art of yodeling. The courses begin in the 2018-2019 academic year. Yodeling was traditionally used by Swiss herdsmen to communicate in the mountains. The form of singing which involves wobbling the voice in an up and down pitch was later adopted by musicians. Yodeling is enjoying a comeback in Switzerland even charting on albums last year.
