At the age of 17, she began to train her voice with opera singer and music educator Hedevig Quiding (16 September 1867 - 22 October 1936).

Her debut at Nykøbing Falster was a great success, and she signed on to a 10 year contract to perform at the National Scala revues.

In 1930, she performed as a guest at the Royal Danish Theatre as Pernille in a satirical play The Fidget by Ludvig Holberg.

He wrote many of the songs that are today associated with Liva Weel such as "Man binds us by mouth and hand" from the Dyveke revue in Riddersalen theatre.
