She has appeared with numerous international orchestras and has plays regularly in the Bayreuth Festival Orchestra.
Claudia Stein is a teacher and mentor in the academy of the Berlin State Orchestra and as of 2015 she teaches in the Barenboim Said Academy Berlin. Her pupils have gone on to win positions in prestigious orchestras in Marseille, Düsseldorf, Kassel and Berlin. Claudia is also active in the music kindergarten Berlin, a unique project initiated by Barenboim. She worked on some of the pedagogical ideas leading to its foundation.
