The estates of the Luxembourgish composers Lou Koster and Helen Buchholtz are available to the young researchers in order to explore questions relating to the handling of composers' estates using concrete material and, above all, to delve deeper into questions of gender and analysis, marginalisation and composing in a "marginal" music-historical location. The research workshop comprised a preparatory phase, two seminars (including a student symposium, guest lectures from Luxembourg and an excursion to Luxembourg). Two master's theses (Oliver Retz and Kerstin Schäffer) emerged from the seminar topics, in close co-operation with the archive of the Cid femme; the conception and realisation of a symposium in Luxembourg (2012) is currently in preparation. This project took part in the presentation "Forschendes Lernen", Nov. 2010 at the Universities of Oldenburg and Bremen(poster).
