Yodeling is so much more than just a way of singing. I heard once that it first evolved from a way of communicating between mountaintops. Aside from music, you can use it to stop traffic, as a repellent for most kinds of large mammals or - possibly with enough skill, you could use it to strip old paint off buildings.
Yodeling is typically thought of as folk music from the alps, but several cultures have yodeling or something that resembles yodeling in their music. It's also become popular in some cultures it is not endemic too such as american country and bluegrass.
So do you have a favourite yodeler?
I do, the amazing Franzl Lang from Bavaria
Here he is performing the classic appenzeller yodel (mein Vater ist ein Appenzeller = my father is an apple-salesman).
Listen to this and be honest. Does it not make you want to strap on some lederhosen, drink massive amounts of beer from mugs with lids on them and gorge on bratwurst?
