While she enjoyed singing at school and in church, Etting never took voice lessons. She said that she had patterned her song styling after Marion Harris, but created her own unique style by alternating tempos and by varying some notes and phrases. Describing herself as a "high, squeaky soprano" during her days in David City, Etting developed a lower range singing voice after her arrival in Chicago which led to her success. Her big moment came when a featured vocalist suddenly became ill and was unable to perform. With no other replacement available, Etting was asked to fill in. She quickly changed into the costume and scanned the music arrangements; the performer was male, so Etting tried to adjust by singing in a lower register. She became a featured vocalist at the nightclub.
