Yodeling (also
yodelling or
jodeling) is a form of singing which involves repeated and rapid changes of pitch between the low-pitch
chest register (or "chest voice") and the high-pitch
head register or
falsetto. The English word
yodel is derived from the
German (and originally
Austro-Bavarian) word
jodeln, meaning "to utter the syllable
jo" (pronounced "yo" in English). This vocal technique is used in many cultures worldwide.
