"Auf Und Auf Voll Lebenslust" (Everyone Lives in Passion) by the famous German singer Franzl Lang.

Yodeling, also known as yodeling. It is a singing form that is fast and repeatedly performs large-span scale transitions between chest articulation and head articulation. Can produce a series of high-low-high-low sounds.

Yodeling is a special singing method and song originating from the Swiss Alps. In the mountains, shepherds often use horns and shouts to call their sheep and cattle, and they also use songs to convey various messages to their friends and lovers on the opposite mountain or valley. Over time, they actually developed a very interesting and amazing yodeling method. The characteristic of this singing method is that at the beginning of singing, you sing with your real voice in the middle and lower ranges, and then suddenly use your falsetto to enter the high range, and use these two methods to sing alternately quickly, creating a unique effect.
