„To what stances can human voice take us when its accents raise? Where?
Do the heavens vibrate from hearing it? Do they?

Or could it be carried away forever by a wind that nothing would hold?“
(Rainer Maria Rilke, Chant éloigné).

Everything sings to me when words are no longer enough!

As a child, I used to sing my way to bed, to digest, to bear my motion sickness, face up with school, survive holidays, seduce my first love, make people laugh, spread nostalgia and my joy at the seashore of my native Brittany. Singing as always been my gear, helping me to grow up, to gain self-confidence. As far as I can remember, my heart was always drown to things and people first through their sounds and voices.

As a teenager, I coud have simply forgotten to breath as I used to listen the sulfurous and low voice of Greta Garbo as Marguerite Gauthier. Thanks to her, I discovered Verdi’s Traviata and the immense range of sentiments on a live stage. I then realised how I wanted, just like her, to sing stories, communicate dispair and joy.

I now every day fill up my soul and my heart with this unchanged enthousiasm. Singing is an act of peace bringing together all nationalities and make me keep faith in the future of our world.
My love for theater, languages, humanity, discipline, for life through music, permanently seeking the most honest serving of a text,… Who knows? I might as well manage to make you forget to breath for a second? Here is my singing.

Let´s find your voice together, give it life, define it or polish it: an adventure with open heart! My drive: enthousiasm through singing, my pleasure to transmit my art, the passionate search for one´s intimate instrument. through the multiple ways music can offer. Together unfolding our voice, and giving it stamina in a peaceful and healthy manner. Pointing out tensions, taming the fears thanks to precise physiological explanations, a musical line and an honest serving of the text.

I will prepare you for auditions, competitions, getting a first foot in the Conservatoire, recitals and recordings. We will define together your goals and establish a concrete, daily programme in full respect with your unique instrument.

As a French mezzo-soprano, I established myself in Vienna 12 years ago. I started my musical education by studying Cello during thirteen years. I then graduated in singing from the French National Conservatoire in Lyon and the Schola Cantorum in Paris. I sang in the finals of the international world singing competitions „Operalia“ and „Les Voix Nouvelles“. Thanks to my experience, I then entered the prestigious ensemble from the Vienna Opera House where I performed numerous roles over ten years.

I have performed on stage aside international leading singers like Anna Netrebko, Jonas Kaufmann, Nina Stemme, Ludovic Tézier, Bryn Terfel, Véronique Gens and Roberto Alagna, as I have been able to broaden my repertoire at the highest level on international stages like the Wiener Volksoperm the Theater an der Wien and also festivals of contemporry music, the Théâtre de Champs-Elysées in Paris, the Concertgebow of Amsterdam, The Bavarian Radio, The Palazetto Bru-Zane of Venice. I also sing sacred music on a regular basis in churches like Saint Augustinus and the Stephans Dom in Vienna.

Since I started my career, I have already sung over 45 roles and collaborated with worlwide renowned conductors, such as Christian Thielemann, Marco Armiliato, Peter Schneider, Fabio Luisi, Bertrand de Billy, Leo Hussain, Simon Rattle… But also directors like Peter Konvitschny, Christophe Loy, Robert Carsen and Marco Arturo Marelli… These artistic collaborations feed my work and help me find a permanent regenerated inspiration for my vocal work. The freshness of the voice and delivering true feelings are my main objective.

In parrallel to my singing career, I give regular workshops and coachings on French pronunciation for solo and choir singers in various Opera houses:I teach french Fonetik and pronunciation in the Musik und Kunst Privat Universität of Vienna (muk.at), I give singing Lessons in the franco-german Conservatoire (Conservatoire.at) and i have experience in early musical education too.

Just like any other singer, I have already experienced vocal fatigue and doubt. Singing is life. Singing is passion and a source of permanent self achievement. Healthy singing will help you get back on your feet.

Your first singing lesson shall be free of charge.
Fee: 70€ per hour.
Student fee: if 10 lessons booked, 60€ per lesson.
French pronunciation coaching: 45€ per hour.
