Belting, as it is commonly referred to in a modern American sense, can trace its origins back to the minstrel shows and the Vaudeville circuit of the Mid to Late 19th century.
[4] Belting became commonplace in Broadway musicals following Ethel Merman's performance in Girl Crazy (1930), notably in the song "I Got Rhythm".
However, it is important to note that belting research is still evolving and changing as voice scientists learn more about vocal function and perception.
This technique contrasts with traditional western classical schools of thought that do not advocate for the spreading of vowels and raising of the larynx at high registration events.
Indeed, some genres of singing (such as blues rock) rely on belting to allow the vocalist to "cut through" the electric guitar while playing live.
