French tenor Jean Miannay studied singing in Lausanne with Brigitte Balleys, and in Berlin with Scot Weir. He distinguished himself in 2018 at the 4th Raymond Duffaut Competition, where he won the Grand Prize. He went on to win prizes at the Clermont-Ferrand Competition, the Kattenburg Competition and the 2nd Vienna International Music Competition.

His young and lyrical voice has taken him to roles such as Tamino (Die Zauberflöte), Ferrando (Cosi fan tutte), Beppe (Pagliacci), Nemorino (L'elisir d'amore), Alfredo (La traviata), Vincent (Mireille), and Des Grieux (Manon).

In 2018, he made his stage debut at the Opéra de Lausanne, where he has since performed regularly. He has appeared there as Nemorino (L'Elisir d'amore), Ferrando (Cosi fan tutte) and Monsieur Triquet (Eugen Oneguin).

He made his French debut as Beppe (Pagliacci) at the Massy, Avignon and Clermont-Ferrand operas.

In 2020, he appeared for the first time at the Chorégies d'Orange during the "Nuit Magique". He returned the following three years, for the Emerging Stage recital, the role of Isepo (La Gioconda) and that of Remendado (Carmen).

In 2022, he made his German debut as Orpheus (Orpheus in der Unterwelt) at the Theater Magdeburg.

For the 2023/2024 season, he joined the Opéra National du Rhin studio.
