Felix Mahr specialized in teaching the classes of the Preparatory Program at the Barenboim-Said Akademie. Ideally, music theory helps the students to understand their repertoire better, to practice more effectively, to interpret more independently and to communicate their musical perspective more concisely. Therefore, it is his main didactic principle to support students individually without ignoring necessary basic competencies.
