The term ALPINE WARBLE is a combination of two words, YODEL and ALPINE. YODEL is a form of singing that involves rapidly changing between the normal voice and falsetto, and is often associated with ALPINE culture. ALPINE refers to the mountainous region of Europe, which is home to many traditional yodeling songs. Together, the two words form the term ALPINE WARBLE, which can be used to describe the traditional style of singing found in the Alps.
