One thing you've got to know is that yodeling is different for men and for women. Men have "two voices," their deep, adult voice, where the sides of the vocal folds come together, and their falsetto voice, where the edges of the vocal folds come together. (This is how woman and children talk. Men can keep this in practice and so sing falsetto if they wish.)
Male yodelers show off by hopping from normal to falsetto. Women don't.
Could trying this the wrong way damage your nice voice? I don't know.
BTW, switching from deep to falsetto seems to be a tradition in Delta Blues, too.
