Yodel is a traditional folk singing technique, generally believed to have originated from the Central Alps, and have developed from the shouting voice that used by Swiss and Austrian herders in calling their stocks, and communicating with other herders for a long-distance. It is a high-difficulty skill that requires the singer to constantly and rapidly switch between the chest voice (low pitch) and the falsetto (high pitch).
