MATRIX is a documentation and education centre for new music. Its library (which is embedded in the Leuven University Library) comprises a large collection of books, scores and recordings of post-war music, and information files on Flemish composers. All items are catalogued in an online database and can be consulted in the reading room.
Moreover, MATRIX organises exhibitions, conducts projects regarding contemporary heritage and produces publications on relevant themes and significant composers. These publications can have the form of booklets, e-publications, websites and collections of scores. The educational staff organises workshops, classes, amateur productions, and summer schools (for example the Nadar Summer Academy), in close collaboration with (music) schools, festivals, ensembles, etc.
MATRIX also acts as the Flemish section of the International Society for Contemporary Music (ISCM).
