Marion Leleu
The French violist Marion Leleu studied viola and choral conducting at the CNSM in Lyon, graduating with honors. First she worked for many years as an orchestral musician, among others at the Hamburg State Opera and the Kammerakademie Potsdam, but also in many other ensembles in which she was a guest. These include the Chamber Orchestra of Europe, the Orchestre de Radio-France, the Ensemble Modern, the Bavarian State Opera, the Dresden State Opera and the Akademie für Alte Musik Berlin.

She has been passing on the stage experience she gained there at the UdK Berlin since 2008. She is passionate about pedagogy and psychological support for other musicians to help them perform at their best. Her coaching method is based on the technique of tapping acupressure and positive visualization. She has given several advanced trainings and workshops for instrumentalists in this field at the Rostock State Academy and in Brandenburg.

As a musician still passionately on the road, she has shifted her concert activities to demanding chamber music, for example with the sonata duo "ALTOPIANO" and the historical string quartet "Quatuor Voltaire", which she co-founded.
