Her melodramatic soprano repertiore covers a wide area od operatic parts, which are enabled by her voice type "soprano spinto d'agilita": Tosca, Manon Lescaut, Elza (Lohengrin), Salome, Venuss (Tannhauser), Eglantine (Euryanthe), Lucrezia Contarini (Due Foscari), Abigaille (Nabucco), Joan of Arc (Joan of Arc), Judith (Bluebeard’s Castle), Santuzza (Cavelleria Rusticana), Marina (Boris Godunov), Lucrezia Borgia (Lucrezia Borgia), Kostelnicka (Jenufa), Witch and the Foreign Princess (Rusalka), The Fox (The Cunning Little Vixen) and
Wozzeck on the compositional direction of "Wozzeck". In a letter to his wife written in June 1918, he wrote, "There is a little bit of me in his character, since I have been spending these war years just as dependent on people I hate, have been in chains, sick, captive, resigned, in fact, humiliated." His correspondence and notebooks dating from the war years reveal a painful obsession with completing "Wozzeck". Compositional sketches and notes for both Wozzeck and the "" of Three Pieces for Orchestra that Berg made during the war are strewn with disjointed fragments of military ordinances and terminology.
