Yodeling is a form of singing which involves repeated and rapid changes of pitch between the low-pitch chest register and the high-pitch head register or falsetto. The English word yodel is derived from the German word jodeln, meaning "to utter the syllable jo". This vocal technique is used in many cultures worldwide. Recent scientific research concerning yodeling and non-Western cultures has shown that music and speech evolved from a common prosodic precursor.

James Charles Rodgers was an American singer-songwriter and musician who rose to popularity in the late 1920s. Widely regarded as the "Father of Country Music", he is best known for his distinctive yodeling. Rodgers was known as "The Singing Brakeman" and "America's Blue Yodeler". He has been cited as an inspiration by many artists, and he has been inducted into multiple halls of fame.
