Well, 3 or 4 years ago I decided to go ahead and "fake" a Jimmie Rodgers type yodel in songs that called for it and even to add a semi-yodel to songs like "Lovesick Blues."   To my surprise, I got better and better with practice - even though I don't know what I'm doing. (I.e., I'm still just sort of imitating a yodeler.)    Now I even sometimes get kudos for it.
At least people don't laugh at me any more when I try to yodel. (Usually) ; )
