Science Discovers the Secret of Caruso’s Marvelous Voice – Strength Magazine – December, 1922

Every normal human being has a Hyo-Glossus muscle in his or her throat. A few very fortunate persons -like the ]ate Caruso -are born with the ability to sing well. But even they must develop
their natural gifts. Caruso had to work many years developing that muscle before his voice was perfect. Whether your voice is strong or weak, pleasant or unpleasant, melodious or harsh, depends upon the development of your Hyo-Glossus muscle.
