What is the name of the European ballad with the many lines "Oh Lilly Oh Lilly Oh Lilly Oh Lilly Oh Lilly Oh Lilly Oh"?

Yodeling, also known as yodeling. Yodeling is a form of singing that involves large scale transitions between chest and head articulation at a high tempo and over and over again. It produces a series of high-low-high-low sounds.

Yodeling is a special style of singing and song originating in the Swiss Alps. Shepherds in the mountains often use horns and shouts to call Yoder to call their flocks, herds, but also with the song to the opposite side of the mountain or valley of friends, lovers to convey a variety of information. Over time, they have developed a very interesting and amazing Yoder singing.

Yoder songs are sung by soloists, as well as multiple voices, or by a soloist, many people respond to the same. The forms are varied but the singing style is uniform. Traditional Yoder is generally sung without instrumental accompaniment or accompanied only by cowbells. Due to regional differences, the traditional Yoder singing style is not the same. There are differences in each region and even in the interlocking valleys (the most important of which are in tempo and rhythm), creating what is known as the Yoder dialect.

Jodl singing and its songs first arose in the German-speaking part of Switzerland at the northern foot of the Alps, and later spread to all of Switzerland and to Austria and southern Germany. It is one of the wonders of European folk music and an important cultural tradition in this region. 1912 Switzerland officially established the Yoder Society. By 1975 there were more than six hundred chapters with over 15,000 members. Swiss descendants in New Zealand have also preserved the Yoder tradition. It was brought to the United States with immigrants and became one of the main means of expression of American country and bluegrass music.

In recent years, the influence of yodeling and song has grown, with the song "The Lonely Shepherd" from the movie "The Sound of Music" being derived from the yodeling style. There is also a lot of pop music with Yoder's elements, such as the widely circulated "Cattle at Dusk" and "Ballad of Fire" sung by Lin Yilun.
