Switzerland’s yodeling tradition began in remote Alpine meadows, but now, new generations of students can opt to learn the folk art in a college classroom. The Lucerne University of Applied Sciences and Arts has become the nation’s first university to offer bachelor’s and master’s degrees in yodeling, according to The Local.

Lucerne University has offered folk music degrees since 2012, but it took the department several years to find a qualified yodeling teacher. They finally settled on Nadja Räss, a famous Swiss yodeler who runs her own academy in Zurich. Under her tutelage, three to four incoming students will learn to yodel-ay-ee-oo while also taking classes in musical history, theory, and business.

Yodeling is today performed on stages, but it was once used as a method of communication among Alpine shepherds. By alternating falsetto notes with natural singing tones, they were able to communicate across mountains and round up livestock. These lyric-less cries developed into songs by the 19th century.

Today, the technique is no longer just for shepherds. Yodeling is undergoing a musical revival and occasionally enjoying five minutes of YouTube fame.

In 2014, Swiss officials announced that they intended to submit Alpine yodeling for consideration to UNESCO’s World Heritage list, along with traditions like mechanical watchmaking, typography, and managing the risk of avalanches, according to The Telegraph. Due to current guidelines, countries can only supply one entry each year. At least Switzerland’s yodelers will now have new opportunities to study their craft as they await their chance to shine on the international stage.
