José Ansaldi is a Chilean-Italian tenor specializing in Wagnerian repertoire. Based between Vienna and Alicante, he began his musical training at the Conservatorio de Música Isidor Handler in Viña del Mar, Chile, and later continued his studies in Barcelona at the Cor Jove del Palau de la Música Catalana.

Performing early in his career as Leon De La Guardia, he appeared as a lyric tenor in roles such as Don José (Carmen), Rodolfo (La Bohème), Pinkerton (Madama Butterfly), Luigi (Il Tabarro), Ismaele (Nabucco), Arvino (I Lombardi), Alfredo (La Traviata), and Macduff (Macbeth). Engagements followed at the Rudolfinum in Prague, Vienna Konzerthaus, Teatro Arriaga in Bilbao, Arena di Verona, Teatro Petruzzelli in Bari, and in North America with Sun Valley Opera and Opera Kelowna.

He developed his technique through scholarships supporting masterclasses with artists including Jaume Aragall, Carlos Álvarez, Isabel Rey, Juan Oncina, Gianni Maffeo, Angelo Loforese, Nicola Martinucci, Gianfranco Cécchele, and Salvatore Fisichella. His ongoing teachers include Michael Rhodes, Antonio Carangelo, and Laura Briolli.

After transitioning to the Wagnerian repertoire, he resumed performing under his birth name. He studied with Jendrik Springer, assistant to Christian Thielemann at the Bayreuth Festival and to Philippe Jordan at the Vienna State Opera. He received the Ramón Vinay Scholarship from the Wagner Foundation in Chile and the FIA Scholarship from the Ibáñez Atkinson Foundation in 2021 and 2022. His Wagner roles include Siegmund (Die Walküre), Loge (Das Rheingold), Parsifal (Parsifal), Siegfried (Siegfried), and Erik (Der fliegende Holländer).

In 2022 he appeared in the University of Karlsruhe’s production Wider das Verlöschen, earning recognition from Prof. Dr. Stephan Mösch for his performance. His German debut as Siegmund in Die Walküre under Marcus Bosch made him only the second Chilean tenor to sing this role in Germany. In 2024 he sang Der Kaiser in Richard Strauss’s Die Frau ohne Schatten at the Neuköllner Oper in Berlin.

In 2025 he made his house and role debut as Herodes in Strauss’ Salome at Teatro Colón in Buenos Aires under Philippe Auguin and closes the year with his debut as Erik in Der fliegende Holländer with Opera Catalunya.
