After studying law and political science, Jacques Gay entered the Conservatoire National Supérieur de Musique de Paris where he was awarded the first prize for lyrical art.

During that time, he attended the theatre classes of Jean Laurent Cochet at the Théâtre Hébertot in Paris. He then tackled the greatest roles in the opera repertoire: Figaro (The Marriage of Figaro), Marcello (La Bohème), Valentin (Faust), Escamillo (Carmen), Germont (La Traviata), Bartholo (The Barber of Seville) and the operetta The ViceKing of La Périchole The Baron from La Vie Parisienne, and  the General Boum from The Grand Duchess of Gerolstein.

The Theater has the fabulous virtue of being able to bring you to life a thousand characters, to get out of your daily life and to allow you to express and let go of things that you would not dare to say outside of this context.
