Alpine Tunes is a term used to describe traditional folk music from the Alpine region of Europe. Yodels, which are six letters long, are a type of vocal technique used in Alpine music. Yodeling is characterized by rapidly changing between the chest and head voice, creating a melodic sound. It is often used to imitate the sound of nature, such as birds or waterfalls. Yodeling has been a part of Alpine culture for centuries and is still popular today.
