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.

"Lovesick Blues" is a Tin Pan Alley song, composed by Cliff Friend, with lyrics by Irving Mills. It first appeared in the 1922 musical "Oh, Ernest", and was recorded that year by Elsie Clark and Jack Shea. Emmett Miller recorded it in 1925 and 1928, followed by country music singer Rex Griffin in 1939. The recordings by Griffin and Miller inspired Hank Williams to perform the song during his first appearances on the Louisiana Hayride radio show in 1948. Receiving an enthusiastic reception from the audience, Williams decided to record his own version despite initial push back from his producer Fred Rose and his band.
