Blue yodeling[1] ( meaning 'melancholy yodeling') is a musical style that essentially consists of a combination of elements of blues and old-time music, enriched with characteristic yodelings. Initially sometimes referred to as yodeling blues, it reached its greatest popularity during the 1920s and 1930s in the United States, Canada and Australia.
The name goes back to the song title Blue Yodel, under which the American singer Jimmie Rodgers published a total of twelve numbered songs that were groundbreaking for the development of early country music. In addition to Rodgers, the later "Singing Cowboy" Gene Autry and the Honky Tonk Musicians Ernest Tubb and Hank Snow were outstanding representatives of the genre.
