This work aims to delve into the inner world of the composer Federico Mompou (1893-1987) with special focus on the artistic and philosophic concepts that make his aesthetic so unique within music history. Thereore, apart from biographical data, the connections between his music and ideas that belong to the existentialist and pantheist movements will be presented.

Nevertheless, the ultimate objective of this project is the configuration of a piano solo recital program which, containing works from different periods and composers shows the essence of Mompou's inner world to the audience. For that, I have focused on the part of that world that is presented in what I have called his "mystic music" (pieces inspired by the imagination of the spiritual, religious or magic universe). The process of selection of the program is fully explained and justified in the thesis.
