Despite so many experiences, he never forgot his style of presenting music in direct contact with the audience,
developing a special intuition, to know the right kind of repertoire at each moment.
Matthias Müller has made it his goal to bring back the people in organ and harmonium concerts with his chosen, interesting pieces, who have stayed away from these concerts through programs with difficult-to-hear works or who are trying to gain new lovers for these instruments. Even the smallest organ he can elicit a concert program due to its large repertoire. That's why he likes to play there where there are no concerts or the "Dorforgel" is supposed to be unusable for a concert. The personal presentation of the played works, the spontaneity of the program selection and his closeness to the audience make him a welcome guest everywhere.
