Italo Tajo was an Italian operatic bass, particularly associated with Mozart and Rossini roles.
Tajo was born in Pinerolo, Piedmont, and studied violin and voice at the Music Conservatory of Turin with Nilde Stichi-Bertozzi. He made his stage debut in 1935, as Fafner, under Fritz Busch. At Busch's invitation, he followed him to Glyndebourne, where he became a member of the chorus, also appearing in comprimario roles.
In 1939, he was back in Italy, where he became a member of the Rome Opera, in 1942 taking part in the Italian premiere of Berg's Wozzeck. In 1940, he joined the Teatro alla Scala in Milan, where he sang regularly until 1956. He appeared with the Maggio Musicale Fiorentino in 1942, as Leporello in Don Giovanni, a role he would sing numerous times during his career. In 1961, the bass was in the world premiere of Luigi Nono's Intolleranza 1960, in Venice.
The war over, his career quickly took an international turn, with debuts in Paris, London, Edinburgh and Buenos Aires.
