Aspiring to be an opera singer, she worked as a shop-girl at a tailor store called the Galeries Lafayette, saving some of her earnings, and portions donated to her by Gauty's parents to receive a classical music education at Nelson Fyscher in Paris.

In 1922, Gauty began her musical career as a cabaret singer at variety shows arranged by operetta composer Georges Van Parys, who accompanied her on piano.

[1] She married her booking agent, Swiss music director Gaston Groeuer, who had taken over ownership of the Theatre des Dix Heures in Brussels, Belgium.

[4] Gauty was awarded a Grande Prix du Disque for her role in the French adaptation of German composer Kurt Weill's The Threepenny Opera.

When a period of rampant antisemitism had spread across France in the mid-1930s, Gauty was one of the few artists to show her support for the Jewish people by singing the composition "Israel, va-t'en".
