Darmstädter Ferienkurse
Darmstadt School refers to a group of composers who were associated with the Darmstadt International Summer Courses for New Music (Darmstädter Ferienkurse) from the early 1950s to the early 1960s in Darmstadt, Germany, and who shared some aesthetic attitudes. Initially, this included only Pierre Boulez, Bruno Maderna, Luigi Nono, and Karlheinz Stockhausen, but others came to be added, in various ways. The term does not refer to an educational institution.
