After studying with the baritone Arturo Pessina in Turin, Pasero made his debut there, during 1917, as Ramphis in Verdi's Aida—although he always considered his official operatic debut to have taken place in Vicenza, on December 15, 1918, as Rodolfo in Vincenzo Bellini's La sonnambula.
Later he performed in theaters in many Italian cities, like Bologna, Mantua and Venice, and performed important works such as Rigoletto, La sonnambula, L'amico Fritz, Iris, and Manon.
She remained committed to that house through 1920 where her other roles included Adina in L'elisir d'amore, Amina in La sonnambula, Elvira in I puritani, Gilda in Rigoletto, Rosina in Il barbiere di Siviglia, and the title roles in Lakmé and Mireille.
