Lane,

Just did a concert with Doc Watson Sat. night. Doc yodels on many songs sometimes just the standard octave jump, which I also do. On the octave jump you just take the vowel sound of the word you are singing and yodel it an octave higher.

The amazing thing about Doc is that his yodeling has improved over the last ten years, he's almost 80 now.

Doc also yodels (or sings falsetto) entire passages of songs. A similar type of falsetto singing has been done by Barry Gibb of the Bee-Gee's.

So, this type of singing is not just limited to standard yodel sounds.
