Yodeling is a vocal technique once used by shepherds in the Swiss Alps. To yodel, you first have to find your normal, or "chest," voice, and your high, or "head," voice. Yodeling involves switching between these two ranges of sound, or registers, and finding the break between them. To begin, make an "ah" sound and move your voice from low to high, listening for the break. Try to keep your voice relaxed, but don't allow the notes to flow smoothly. Unlike other styles of singing, yodeling requires you to emphasize the break between notes. Which author's purpose is suggested by the text?
