Yodeling in the context of "Swiss art"

The Good, the Bad and the Ugly: Original Motion Picture Soundtrack was released in 1966 alongside the Western film The Good, the Bad and the Ugly, directed by Sergio Leone. The score is composed by frequent Leone collaborator Ennio Morricone, whose distinctive original compositions, containing gunfire, whistling, and yodeling permeate the film. The main theme, resembling the howling of a coyote, is a two-note melody that is a frequent motif, and is used for the three main characters, with a different instrument used for each one: flute for Blondie, arghilofono for Angel Eyes, and human voices for Tuco.

Among other elements, the score complements the film's American Civil War scenes, containing the mournful ballad "The Story of a Soldier", which is sung by prisoners as Tuco is being tortured by Angel Eyes. The film's famous climax, a three-way Mexican standoff, begins with the melody of "The Ecstasy of Gold" and is followed by "The Trio".

The New Guinea singing dog or New Guinea Highland dog (Canis lupus hallstromi) is an ancient (basal) lineage of dog found in the New Guinea Highlands, on the island of New Guinea. Once considered to be a separate species in its own right, under the name Canis hallstromi, it is closely related to the Australian dingo. The dog is relatively unusual among canines; it is one of the few to be considered "barkless", and is known for the unusual "yodel"-like style of vocalizing that gives it its name.

In 1989, the Australian mammalogist Tim Flannery took a photo of a black-and-tan dog in Telefomin District. He noted that these dogs lived with local tribal peoples in the mountains, and that feral populations lived in the alpine and sub-alpine grasslands of the Star Mountains and the Wharton Range. The photo was published in his book, Mammals of New Guinea. In 2012, Australian wilderness-adventure guide Tom Hewett took a photo of a tawny, thick-coated dog in the Puncak Mandala region of West Papua, Indonesia. In 2016, a literature review found no definitive evidence that the earliest possible dogs, within captive populations of New Guinea singing dogs, were wild animals; successive generations of puppies were raised as members of village populations, thus being domestic dogs.
